aluminum oxide cas is a white powder that is used in glass, ceramics, refractories, and as an abrasive. It is one of the hardest and most chemically inert oxides. It is also very resistant to air vapor, water vapor, and sulfurous atmospheres.

It is a white, crystalline substance with a melting point of 2050degC. It can be a pure crystalline form or mixed with other materials such as chromium, silica, iron, and magnesium.

Alumina is a naturally occurring mineral. It is found in bauxites and laterites as well as in other minerals. Alumina crystals can be synthesized, or derived from bauxite in a number of ways. The primary methods are to leach bauxite with caustic soda and to hydrolyze and seed the solution.

The hydrolysis of bauxite in base solution produces a hydrated alumina oxide. The hydrated alumina is then filtered and calcined to remove water.

This alumina is then sold to abrasives manufacturers who are looking for a very hard, abrasion-resistant material. The abrasives made from it are used for grinding and sanding.

They are used on tools, metal castings, machining components, and a variety of other applications. They are also used in the production of dental implants, bionic eye substitutes, hip replacement prostheses, and tissue reinforcement materials.

Chronic inhalation of aluminum oxide dusts has been associated with silicosis in workers. Inhalation of aluminum oxide particles that are fluoride-adhered, as opposed to the finely divided particles that are free of fluorides, results in a more irritating agent for the respiratory tract.
