Fused corundum with high-quality bauxite as the main raw material, through the use of electric arc furnace at high temperature above 2200 purified, purify, crystallization, sorting, crushing, magnetic separation, screening and other means of processing a variety of particle size is made products. Has a high hardness, self-willed big, shock, high temperature resistance, anti-oxidation, corrosion resistance, low creep and so on. Its main components are AL2O3, TiO2, SiO2, and Fe2O3 and so on.
Made with corundum abrasive grinding sharp, heating rate is low, grinding than high, and the buildup of little use; made of sintered abrasive has a dark blue color after firing, can not afford to mesh cracks, no pitting of the characteristics, applicable to the manufacture of ceramics, resin, as well as the high-Bonded Abrasives grinding, polishing and so on.
