Calcined Alumina Powder

1.Commercial Aluminum Hydroxide：

The bauxite was diluted with sodium hydroxide solution to obtain sodium aluminate solution and then add the seed. After stirring, aluminum hydroxide will be come out.

High Purity, low heavy metal content, moderate activity, easily soluble in acid and alkali.

All kinds of aluminum compounds; Flame retardant additives for flammable materials (such as plastic, rubber, paper, pigment and coating); Water purifying agent, desiccant, glass and building materials, and fillers, etc.

2.Calcined Alumina：

Through Bayer process, the alumina in bauxite is decomposed into alumina in sodium aluminate solution, and then calcined into alumina under 1200-1300 temperature. It can be used for refractory, structural ceramics, abrasive and electronic ceramics.
