Ceramic calcined aluminapowder
Ceramiccalcined alumina powder with the formulaAl2O3. This is a white color crystallinesolid, sand-like shape. Calcinedalumina is white crystalline powder, and we get is by calciningaluminum hydroxide. There are different categories of calcinedalumina. The most stable and useful one is α-alumina and it isthermally stable with a high melting-point, and its hardness issimilar to diamond. Besides it has high electric resistance and isstable against acids and alkalis. It can be used as raw materialsfor aluminous refractory, ceramic products, sparking plugs andgrinding material. Customers choose the products according chemicalcomposition and physical properties.
