Calcined Alumina KC Part

Calcined Alumina KC Part 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 3~5µm. SA-50D is used for manufacturing sintered alumina or spinel The unit crystal size is 0.5~1.0µm. CA-5M is the normal fine product made by milling calcined alumina. It is widely used for refractory, abrasive, fine ceramics. It's unit crystal size is 3~5µm Specifications Product name CA-83F CA-50F SA-50D CA-5M ChemicalProperties Moisture(%) Max 0.10 Max 0.10 Max 0.10 Max 0.2 Al2O3(%) Min 99.6 Min 99.6 Min 99.6 Min 99.6 Na2O(%) Max 0.30 Max 0.35 Max 0.30 Max 0.35 Fe2O3(%) Max 0.02 Max 0.02 Max 0.02 Max 0.02 SiO2(%) Max 0.02 Max 0.02 Max 0.02 Max 0.02 Loss on Ignition(%) Max 0.10 Max 0.10 Max 0.10 Max 0.10 PhysicalProperties Dp50(µm) 60±10 50±10 55±10 4±1 +45µm(%) Min 60 Min 40 Min 50 Max 0.5 Alpha phase(%) Min 95 Min 95 Min 95 Min 95 Specific surface area(m2/g) 0.3~0.7 0.3~0.7 3~7 - Angle of Repose(°) 48~53 50~55 38~43 - Uses Fused alumina, Mullite, Spinel Refractory brick, Castable Sintered alumina, Ceramic fiber High alumina ceramics, Whiteware Abrasive Packaging Bulk Flexible Container Bag(1,000kg) Paper Bag(25kg, CA-50F and CA-5M only)
