To get this kind of product, we treat the regular grains at a medium high temperature to give a light blue colour, the purpose is to renovate the crack on the surface and interior of crystal and then
to improve the toughness and durability of the grains. Typical Chemical Analysis Al2O3 Fe2O3 TiO2 SiO2 CaO 95.84% 0.06% 2.40% 0.93% 0.22% Physical Properties Color Light blue Shape Blocky, tough and
sharp Crystal Form Alpha-alumina trigonal system True Specific Gravity 3.96 g/cm3 Hardness 2090 Knoop scale; 9.0 Mohs scale Melting Temperature About 2050
