What is Nano Silica?

Posted on by adminLeave a comment
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.
