High Alumina Calcined Bauxite Powder
Calcined bauxite powder is a high alumina powder obtained by high-temperature calcination, impurity removal, and grinding of natural bauxite, with the core component being Al2O3. It has the characteristics of high temperature resistance, high strength, and chemical stability, and is a key raw material in refractory, abrasive, ceramic, and other fields.
