- ● CALCINED ALUMINA (CA)Alumina, white crystallized powder, is made by calcining Aluminum Hydroxide and the chemical formula is Al2O3. It is a typical α-Alumina (Corundum) widely used. It is widely used for flame retarders, insulating materials, spark plug, IC board, abrasive, brightener and etc by high melting temperature, high mohs hardness, high electricity resistaibility, stable reactivity to acid and alkali.As CA-83F, CA-50F are calcined Alumina of hexagonal structure, they are used widely for refractory, ceramic, abrasive and etc.The Fine Article content is lower than others and the unit of crystal size is 3-5um. SA-50D is used for manufacturing sintered alumina or spinel.CA-5M is the normal fine product made by milling calcined alumina. It is widely used for refractory, abrasive, fine ceramics. Its unit of crystal size is 3-5um.
