Nano-manufacturer (aka. Technology Co. Ltd. summarized specific applications of Nanosilica after years exploring Nano-powders.
Plastic
Nano-silica Light-transmissive with a smaller particle size. This can make plastics dense. When silica is added to polystyrene, it improves the film’s transparency, strength and toughness, as well as its waterproofing and anti-aging capabilities.

Rubber
Rubber is an excellent elastomer that has good stretchability. However, its overall performance isn’t satisfactory. Carbon black is added to rubber to improve its strength, wear resistance and aging resistance. Carbon black is added to rubber, but this results in a black product. The grade of the product is low. The introduction of nano-SiO2 to China has provided a solid material base for the production of new rubber products that have novel colors and high performance.
When rubber is treated with nano-SiO2, its abrasion and tensile resistance, flexibility and resistance to aging are all significantly enhanced. In addition, the color and color retention effects of the rubber is excellent.
Dye
Organic dyes may have vibrant colors and a high tinting power but they are not as resistant to light, heat, solvents, or migration than inorganics. Addition of nano-SiO2 to organic dyes improves their anti-aging and brightness properties.

Ceramics
Using nano-SiO2 Instead of adding traditional Nano-additives to ceramics, the particles can be added in two phases. This not only increases the toughness and strength of the ceramic but also its hardness and modulus. The performance is better and the effect is more optimal than traditional Nano
additives.
By using nano-SiO2 in the composite of ceramic substrates, not only is the density, toughness, smoothness and smoothness improved, but the sintering temp greatly reduced. The application of nano-SiO2 to ceramic products, such as ceramic filter and corundum ball is also very important.

Sealant Adhesive
Sealants, adhesives, and other important products are widely used and have many applications. This requires the right conditions in terms of product viscosity (liquidity), curing speed, and cure time. Nano-materials have been used as modifiers in many foreign products. Nano-SiO2 has become the most popular. It is mostly coated with a thin layer of organic material to make nano-SiO2 more hydrophobic, and then added to the sealant. It is formed quickly. Nano-SiOX particles are arranged in a network to prevent colloids from flowing, speed up the curing, and improve bonding. A small nano-SiO2 size increases both the sealing and the impermeability.

Glass Product
The FRP materials are light, have high strength and corrosion resistance but have poor wear resistance. Scientists use ultrasonic dispersion to add nano-SiO2 into the gel coat resin. They then compare the performance of the gel without the nano-SiO2. nano-SiO2 Wear resistance has increased 1 to 2 fold. Nanoparticles are grafted and bonded to organic polymers, increasing the toughness and impact resistance of the material. Heat resistance is greatly improved as well, as mentioned above.

Fumed silica can be described as a fine white powder that is made by hydrolysis of silicon hailide at high temperature under an oxyhydrogen flame. It is a form of amorphous silicone dioxide product. The primary particle sizes are between 740nm to 200-500nm. Aggregate particle sizes range from 200-500nm to about 200-500nm. Specific surface area is 100400m2/g. High purity SiO2 content is not below 99.8%. There are a number of silica-hydroxyl groups in vapor phase silicaaggregates with untreated surfaces. One is an isolated, unperturbed free hydroxyl molecule; the other is bonded silyl group that is linked and forms hydrogen bonds to one another. The vapor-phase silica aggregates have the untreated surfaces. They contain multiple -Oh compound, which can easily form an uniform three-dimensional network structure in the liquid system (hydrogen bond). This three-dimensional network structure, called the hydrogen bond, is formed by external force (shear, electric, etc.). The medium will crumble, the medium will thin out, and the viscosity will drop. When the external force is gone, the three-dimensional structure of the hydrogen bond (hydrogen link) will revert to its original state.



Fumed silica, one of the new most important inorganic material, is one. It has a small particle diameter, high specific surface area, strong surface adhesion, large surface energy and chemical purity. Its high stability, reinforcing effects, thickening and thixotropy make it an irreplaceable choice in many unique fields.
It is widely used as an additive, catalyst carrier, decolorizing agent or matting agent in various industries.

Fumed silica is mainly composed of two types of “sex”, hydrophilic or waterphobic. You can use physical, chemical and mechanical methods to alter the fumedsilica interface or surface. This includes surface energy, surface wetability, reaction characteristics, surface structure, functional groups and surface structure. This allows it to be used in modern new material and new technology as well as the requirements of developing new technology.



Hydrophobic fumed Silica Applications
Thickening of certain polar liquids like epoxy resins. Silicone elastomer reinforcement. High addition. Good hydrophobicity. Improved anticorrosion. Powder flow AIDS.

What is Nano Silica? Silicon Dioxide Nanoparticles also known by silica nanoparticles and nano-silica appear in the form white powder.
According to the structure of nanometer silica particles, they can be divided into P and S types. P-type silica particles are distinguished by their large number of nanopores. Their porosity is 0.61 mL/g and have higher UV reflectivity than S type particles. They also have a very small surface area.
Nano silica features a light volume, fluffy bulk density, less than 0.15-0.2g/cm3, an area specific of more than 500m2/g, high chemical activity, and a large surface area.
The surface of nano silica contains an OH bond. This makes it a silicate acid group type. It has hydrophilic water absorption rates that exceed 5 times their own.
Silica nanoparticles have many uses. They are used as additives in rubber and plastic production, reinforced fillers for concrete, and as a platform for biomedical applications like drug delivery and therapeutic diagnosis.

What is Silica?
One of the elements found in the earth’s crust is silicon, also known as silicon. Its oxide forms include silicate (SiO4), and silicon dioxide [silica, SiO2].
It is common to use silicon in industry. The oxide form of silicon is often used in biomedical and industrial applications. SiNPs are rare because of their unique properties. These include ease of synthesis and surface modification, strong mechanical property, and relatively inert chemical structure. SiNPs have been used in biological materials for many decades.
Silica can be found in two forms, crystalline or amorphous. Although they share the same molecular structure, these two basic forms of silica have very different structural arrangements. Amorphous silica exhibits a more irregular lattice arrangement while crystalline silica displays a regular one. Crystalline silica can be found in many forms. Alpha-quartz is the most well-known, and can be transformed by heating to b –quartz, squamous, or quartzite. Porosils are porous crystalline silicon, which is also known as porous silica. All porosils come from synthetic materials.
Because of their rare properties (high surface area, high pore volume and adjustable pore size), silica and Mesoporous Silicon are excellent candidates for controlled drug delivery. Amorphous silicon can be classified into three groups: natural forms and byproducts of power stations or metallurgical processes. Amorphous silica has been considered a promising candidate to carry genes and perform molecular imaging. This is due to its highly adjustable biocompatibility as well as stability. It is used in dental fillers, dental implants, dietary supplements and catheters.

What uses is nanosilica?
The use of nano silica can modify the dispersion or plasticity in cement concrete to increase its impermeability, enhance impermeability, resist frost, reduce hydration heat, and prolong its service life.
It can be used as a vitrification agent, strengthening agent, adhesive, and glue of ceramics, enamels and glazes. It is also used as a high thermal binder in engineering-grade and refractories.
Use nanocomposite materials modifier as an inorganic adhesive at high temperature. Also used as an additive to inorganic composite materials for strengthening, molding and filling rubber/polymer material. Additionally, it can be used in a variety of resin engineering material; High-quality FRP packing that is corrosion-resistant.
It is used to cement seal oil wells and as reinforcement material under-ground engineering.
Use for special purposes, including lamp paint, lubricating oil, thickener or steel dehydrogenate and inner wall paint sensitive material. For solar cells and power cell energy storage.

Is nano-silica toxic?
Exposed to silica, particularly crystalline, has been extensively researched.
Studies have shown that workers are exposed to crystalline silicona at work, which can lead to silicosis. This is a fibrotic lung condition that can also be caused by other diseases such as lung cancer, emphysema, or tuberculosis.
Amorphous silica used to be considered less toxic than crystalline. Recent research has shown that SNPs that are amorphous have toxicity levels similar to crystalline particles. SiNPs’ physicochemical and crystallinity also produce different levels of toxicity in vitro as well as in vivo. Consider safety and possible adverse effects, especially those that may affect the immune system.

Features and Main Applications of Silica Aerogel

Posted on by adminLeave a comment

The main features of silica Aerogel

Silica aerogel’s unique structure gives it the properties of high heat insulation and low sound transmission. Water glass is a rational choice when making silica jelly. Water glass is an alkali silicate made from silicon dioxide, alkali oxides and water. It is also known by the name sulphuricine. Water glass can be classified into two types according to the alkali, which are potassium water glass or soda water glasses. This stage is the most important for silica aerogel production.

Silica aerogel’s main purpose

1. Thermal insulation

The most common application for silica gel in thermal insulation is Silica aerogel is thermally conductive at a level below 0.02W/(m*k) and lower than that of air. Silica aerosol has the highest thermal insulation properties in the current process. It can be used for national defense, industry, scientific, research, etc., in particular in the fields navigation and aerospace. It can also serve as a pipeline insulation. , Insulation glass for refrigeration, heat insulation glass for clothing, heat insulation glass for heat.

2. Catalyst and catalyst

Silica gel’s strength and heat transfer can be continually improved through research and development. This can allow silica aerogel to be used in catalyst carriers and catalysts. Organic fusion of SiO2 & TO2 or cohydrolysis Si with T metal alkoxide can produce TO2-SiO2 Aerogel. It can increase the specific surface area and adsorption efficiency of silica aerogel.


3. Acoustic delay

Silica gel is able to transmit sound through its pores due to its unique porous nanostructure. There will be significant energy loss at this point, which reduces sound wave amplitude and slows down sound speed. Aerogels can also transmit very little in solid materials. This silica aerogel, which is based on silica, has a high speed and a large acoustic interference propagation range. It also has the benefits of high temperature resistance, aging resistance, as well as corrosion resistance. Silica aerogel can now be used in ultrasonic instruments, acoustic instruments, soundproof windows.

What is monocrystalline silicon?

Posted on by adminLeave a comment
What is Monocrystalline Silicon? According to the directions of crystals, monocrystalline and polycrystalline silica are divided.
Monocrystalline Silicon refers to any substance made from some arrangement of silicon elements. Once the molten, elemental silicon has solidified, silicon atoms can be arranged in many crystal nuclei to form a diamond lattice. These nuclei can grow into grains of the same plan direction and form monocrystalline silicon.

Monocrystalline silicon properties
Monocrystalline silicon exhibits quasi-metallic properties and low conductivity. Additionally, its conductivity rises with temperature and it has considerable semi-conductivity. Intinctual semiconductors are ultra-pure monocrystalline silicone. To ultra-pure monocrystalline silica, trace III An elements like boron can be added to increase conductivity. Likewise, adding trace V An elements (such as phosphorus and arsenic) can enhance the conductivity to form N-type Silicon semiconductors.

How does monocrystalline and multicrystalline silicon differ?
Once the molten elemental silica solidifies, silicon atoms form into many nuclei. Monocrystalline silicon forms if the nuclei are formed into grains that have the same plane. Polysilicon, however, is formed if the nuclei become grains with different plane directions. There is little difference in the physical properties of polysilicon and monocrystalline silica.
The raw material to make monocrystalline silicon is polysilicon. Polysilicon also serves as the basis for photovoltaic energy generation and solar cells. Monocrystalline silicon may be considered to the most pure substance on the planet. For general semiconductor devices, silicon purity must exceed 6N. For large-scale integrated systems, the requirements are more stringent and silicon purity must be at least 9N. Monocrystalline silicon is currently available with purity levels of 12N.

Why is monocrystalline silica used in
It is used mainly in solar cells. It is the first application of silicon solar cells. This technology has high conversion rates and mature technology. Silicon solar cells is most commonly used in light-intensive areas like aerospace. Numerous scientific research institutes and manufacturers of monocrystalline silicon batteries have created high-efficiency monocrystalline silicon batteries by using different battery processing technologies and wafer treatment.

How can you create monocrystalline silicon.
Preparation of monocrystalline silicon requires the realization of the transition from polycrystals to single crystals. That is, the atoms of liquid phase are transformed directly from random to orderly arrangement to symmetrical structures. This is not a complete transformation, but it is achieved gradually through movement at the solid-liquid interface. To realize this transformation, polysilicon needs to undergo transformation from solid to molten and finally to solid crystal silica. It is possible to make monocrystalline silicon out of molten silica. The crucible Czochralski technique and the noncrucible suspension area melting method are the most popular. They are called CZ and FZ respectively.
