Product Description

Alumina, also known as aluminum oxide, chemical formula Al2O3, molecular weight 101.96. Non-toxic, Odorless, density 3.9-4.0g/cm3, bulk density 1g/cm3, melting point 2050ºC, boiling point 2980ºC, Insoluble in water, amphoteric oxide, soluble in inorganic Acid and alkaline solutions.

According to different uses, alumina is divided into two categories: one is the alumina used as the raw material for electrolytic aluminum. It is called  metallurgical grade alumina, most of the alumina produced in the world is used for electrolytic Aluminum; the other is used for ceramics, The non-metallurgical alumina used in the chemical, pharmaceutical and other fields,it is called special alumina or chemical alumina. Alumina is mainly produced with bauxite as raw material, and is obtained by Bayer process, sintering process and other processes Aluminum hydroxide, the dehydrated product decomposed by heating, is a white powder or sand.

Application:
It can be used in refractory material industry, abrasives industry, glass and ceramic industry,polishing materials, , sandblasting for construction industry, etc.
