Alumina Powder

 

Native alumina is found as the mineral corundum. Most bauxite is refined by the Bayer process to remove impurities and produce a nominal 99.5% Al2O3 product. Four types of alumina are generally utilized: calcined, tabular, hydrated, and synthetic boehmite. Aluminas are a family of aluminum oxides (Al2O3) that can take many forms. As a general term, “alumina” refers to the lower temperature transition alumina forms.

Purities available from 98% (industrial grade) to 99.999% (high purity grade)
