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.
