High Temperature Calcined Alumina Powder

Introduction of High temperature Calcined alumina powder：
High temperature Calcined alumina powder - micro powder (low sodium, medium sodium, ordinary sodium), its size is uniform particle , it is easy to disperse and strong fluidity, it has good sintering performance. It is the basic raw material for the production of heat resistance and corrosion resistance products, Such as high aluminum refractories, refractory bricks, advanced ceramic products, electric porcelain devices, iron and steel charging materials, high temperature friction materials and raw materials in polishing and grinding products.
