Posted on by adminLeave a comment
Aluminum oxide Aluminum oxide Al2O3 is a chemical compound that has an inorganic formula. This is a hard compound that has a melting and boiling point of 2960degC. It is an ionic crystalline material that can ionize at high temperatures.
Aluminum oxide, also known as aluminum oxide, is a white solid, which is not soluble in any liquid, has no taste or odor, and it’s extremely hard. It absorbs water easily, but it doesn’t deliquescence. Aluminum oxide is amphoteric oxide, soluble and resistant to corrosion in both acidic and alkaline solutions.
Application of nano Aluminum oxide
Lithium separator coating material
The high-purity Nano-Aluminum dioxide is applied as a ceramic layer to the positive/negative electrode separators. This coating can be used to improve heat resistance, resistance to high-temperatures, and insulation. This will prevent the battery from overheating due to temperature. The battery is melted and short-circuited.
Lithium cathode materials additives
High-purity Nano-Aluminum doped by lithium manganate or cobalt oxide. Improve thermal stability, cycle performance and resistance to overcharge, inhibit oxygen formation and LiPF6 breakdown, and avoid contact between LiCo02 with electrolyte. Reduce the electrochemical loss of specific capacity, increasing the specific capacity LiCoO2.
Catalyst Carrier:
High-purity g-type Nano- Aluminum oxide This porous material has a surface area per gram of hundreds of square metres, is highly active, and has a strong adsorption ability. It is widely used in adsorbents, catalysts, and catalyst carriers in the petroleum and petrochemical industries. It also serves as a deacidification for transformer and turbine oils in industry. It has a drying capacity that is equal to phosphorus pentoxide. It can be used again after heating to 175degC at least 6-8 hours.

Anti-caking powder coating
Powder coatings are made with nano aluminum oxide, which has an anti-caking and bulking effect. Nano-Aluminum can be used to prevent powder from agglomerating during summer. It also has excellent storage properties, especially for powders in environments with high temperature and humidity.
Wear-resistant Hardener for Coatings, Rubber, and Plastics
The wear resistance can be improved by up to five times with the addition of Nano-Aluminum. Nano-Aluminum dioxide can be added to paints in order to form a uniform, very hard, fine network structure on the surface. This will protect the polymer paint below the layer from damage. Nano paint offers better scratch resistance than original paint. It has been enhanced by 3 times, and is widely used for automobile paints. Nano aluminum oxide increases the hardness of coatings. By adding 20%, the coating can reach 6-7H. The coating’s transparency is not affected.
Thermoconductivity of adhesives, coatings, and rubbers.
Aluminum oxide nano-scale has high thermal conduction and large spheres of filling. Surface treatment agents like coupling agents can be used to improve the compatibility between the resin and filler as well as the thermal properties of the matrix without reducing their mechanical properties.
Ceramics:
Nano Aluminum oxide is high in purity, has uniform particle sizes, and is easily dispersed. Addition of VKL30 at a rate of 10% to sintered ceramics increases the molding pressure. It also reduces the number of pores. This results in a higher density ceramic green body.
Powder metals:
Nano Aluminum for metallurgy. Small particle size, large surface, high activity. Adding 1-3% Nano Aluminum to the matrix will prevent densification, enlargement of crystal grain, increased hardness and conductivity. Mechanical properties and melting point are also improved.
Polishing:
Aluminum oxide particles are uniform and have a high-spherical profile. It is also a great material for metallographic polishing. It is suitable for a variety of applications including stainless steel mirror, titanium polishing and cast iron polishing.

Introduction toSpherical Al Oxide Powder
Aluminum oxide Oder bauxite Al2O3 is a white powder that is insoluble and refractory. The melting point is 2015 and the boiling point 2980. The relative density is 4.0. Mohs hardness of 8.8. There are two main types of crystals: a and, g. Aluminum oxide is made by heating aluminum hydroxide and dehydrating it. Aluminum oxide is found in nature. This aluminum oxide, also known as corundum has a hardness second only to diamond. However, a few impurities can create corundum with different colors. For example, ruby (containing a small amount Cr3+) or sapphire (containing Fe2+, Ti3+), both of which are now made using molten aluminum dioxide artificial crystallization methods. Artificial gems can be used in industrial technology and are comparable to natural gems in terms their properties. Bearings are used for fast moving parts, like diamonds on clocks and watches. Abrasives and refractories such as corundumcrucible can also be used. They can withstand temperatures as high as 1800 F. Aluminum oxide is one main component of the earth’s crust. Aluminum oxide is the main raw material needed to make aluminum. Aluminum oxide is easily oxidized by oxygen to produce aluminum oxide. Aluminum products placed into the air can form a thin protective layer of dense aluminum oxide protecting the aluminum interior from oxidation. Aluminum oxide is an amphoteric ore, and can dissolve in both acidic and base. Aluminum products aren’t resistant to acid and alkali. Contact with acid or alkali will cause the outer oxide layer to be destroyed. Activated aluminiu oxide is porous and can adsorb many substances. This makes it a popular choice for catalysts, desiccants, and adsorbents.

Physical Properties of Spherical Al Oxide Powder
The particle size aluminum oxide Powder is uniformly distributed. It has high purity and excellent dispersion. It is a powder with a large specific area. It also has high-temperature resistance and inertia. It is Porous. It has high hardness and good dimensional stability. It is often used in the production of catalysts, catalyst carriers, and other green chemical substances. It is used extensively to strengthen and toughen many types of plastics. Excellent dispersion, insolvent waters; Solvent alcohol, propylalcool, propylenegl, isopropylalcool, ethylene glycol monobutylether, acetone and benzene.
The particle size of aluminum oxide powder can be changed to the nanometer level This material can not only retain the exceptional characteristics of regular aluminum oxide powder but also exhibits the electrical, magnetic, thermal and mechanical properties that traditional materials don’t have. Nano aluminum oxide is a novel functional material and is widely used in many fields, such as optics and special ceramics.

Spherical Aluminum Oxide Powder Applications
1. Aluminum oxide is the main ingredient in making aluminum. Aluminum oxide is used primarily to make aluminum.
2. Aluminum oxide is the primary raw material for the electrolytic method to metal aluminum. The purer aluminum smelting process, the better. Aluminum oxide is easier to purify than aluminum dioxide. Aluminum oxide is one main component of the earth’s crust. This includes aluminum clay H2Al(SiO4)*H2O, and alingite (AlO2SO4*9H2O). Natural bauxite, which can be found in the range of 40% to 60%, is the best raw material used for the production of aluminum oxide. The rest are mainly silicon dioxide and iron oxide as well as scattered elements and other impurities. You can separate aluminum oxide from the other impurities by using their chemical properties. The main purification methods are the acid method and the alkali method. Activated aluminiu oxide g aluminum dioxide, a porous metal, can have a surface area of hundreds of meters. It has high activity and can adsorb water, vapor, and many other molecules. This material is often used as an agent, catalyst carrier and desiccant.
3. Artificial aluminum dioxide fiber is an aluminum oxide main component. It contains approximately 5% silicon dioxide to stabilize the crystal phases of aluminum oxide. It is widely used in iron and steel industries in heat treatment furnace and nuclear reactor insulation linings, light alloy reinforcement material, and space shuttle insulation materials. Aluminum oxide fiber is a polycrystalline aluminum dioxide fiber. This fiber is made using the colloid or impregnation methods of organic fiber (precursor mode of organic fiber). Its structure is in microcrystalline form which eliminates any possibility of recrystallization for melt-blown fiber. This fiber exhibits great strength at both high and low temperatures, as well as high resistance to high-temperature and low temperature.
