Applications
1 Pigment grade:widely used as ceramic pigment,enamel pigment,paint colors,glass coating,rubber pigment,plastic pigment special ink,camouflage piant,spray paint etc.
2 Refractory grade:widely used as raw material for refrctory bricks or refrctory castables in garbage incinerator,coal gasifier,glass kiln,petrochemical industry,construction materials etc.
3 Abrasive grade:widey used as polishing compound to polish stainless steel,metal,gemstones,diamond,jade,high precision instruments etc.
4 Fused grade: It widely used as raw refractory material in garbage incinerator,gasifier,glass kiln,petrochemical industry,nuclear industry and other industries.It can also be used as melt spray coating using plasma spray directly to the surface of metal,ceramic,given the high wear resistance,corrosion resistance and high temperature resistance.
5 Electronic grade:used in producing precision electronic material,superfine alloy material,intermediates manufacturing and other special industries.
6 Chromium corundum grade:used in non-fferrous metallurgy industry,petrochemical industry,glass industry etc.
