As CA-83F, CA-50F are calcined Alumina of hexagonal structure, they are used widely for refractory, ceramic, abrasive and etc. The content of fine particle is lower than others and unit crystal size is 3~5㎛, SA-50D is used for manufacturing sintered alumina. It is widely used for refractory, abrasive, fine ceramics. It's unit crystal size 3~5㎛.
