Aluminum oxide Oder bauxite Al2O3 is a white powder that is insoluble and refractory. It has a melting point of 2015, a boiling point of 2980, a relative density of 4.0, and possesses 8.5 Mohs hardness. It comes in a variety of crystal types, with the most common being g and a. Aluminum oxide is made by heating aluminum hydroxide and dehydrating it. Aluminum oxide is found in nature. This aluminum oxide is known as corundum. A small number of impurities can create corundum with a variety color. 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 watches and clocks. 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. Pure aluminum oxide is used as the raw material 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 aluminum oxide that protects the aluminum inside. Aluminum oxide, an amphoteric ore, is soluble in both acids and bases. 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 absorb many substances. This makes it a popular choice for catalysts, desiccants, and adsorbents.
Physical Properties of Spherical Al Oxide Powder

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 is made up mainly from silicon dioxide, ironoxide, and scattered elements. 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, has an internal surface area of hundreds of meters. It has high activity and can adsorb water vapour and many other gases. This material is often used as an absorbent, 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. This fiber is widely used in iron and steel industries in heat treatment furnace and nuclear reactor insulation linings, space shuttle insulation materials and light alloy reinforcement materials. Aluminum oxide fiber is a polycrystalline aluminum dioxide fiber. This fiber is made using the impregnation (colloid) method or precursor method for organic fiber. It has a microcrystalline structure which eliminates recrystallization problems in fiber made with the melt-blown process. This fiber exhibits great strength at both high and low temperatures, as well as high resistance to high-temperature and high-temperature, low bulk density, good chemical stabilities, strong insulation, dielectric, sound absorption, and excellent room temperature tolerance.
