Alumina (Aluminium Oxide) is the most widely used oxide ceramic material. Its applications are widespread, and include spark plugs, tap washers, abrasion resistant tiles, and cutting tools. Very large tonnages are also used in the manufacture of monolithic and brick refractories.
Pink Fused Alumina, also called Pink Fused Aluminium Oxide, Chromium Aluminum Oxide, abbreviated as "PA", belongs to the group of artificial corundum. It's made from fusion of high purity alumina powder and chromium oxide in electric arc furnace. Because of its chrome content, it's a pink color material. Its main content is Aluminium Oxide(Al2O3), with little content(about 0.7% Chromium Oxide and about 0.3% Sodium Oxide(Na2O). Pink Fused Aluminium Oxide is a hard, tough, self-sharpening, low magnetic, coarse grits, pure and clean abrasive material. Compared to White Fused Aluminium Oxide, it has similar hardness, while better strength and cutting side. It's widely used in production of vitrified grinding wheel, resinoid grinding wheel, cutting discs, grinding head and other abrasive tools, also for sandblasting abrasvies, polishing, free grinding, cutting etc.
Tabular Alumina Al2O3 99.2% min Tabular Alumina: The plate-like crystal structure has small pores and many closed pores, and the porosity is roughly the same as that of fused corundum. It has high purity, good volume stability and minimal reheating shrinkage. The refractory or castable used for production has good thermal shock stability and bending strength after high-temperature treatment, but the price is higher than that of other alumina. High fire resistance; High corrosion resistance; High erosion resistance; High thermal shock stability; High strength and good toughness; Stable chemical properties. Tabular corundum is a kind of pure sintered corundum with complete shrinkage without adding any additives such as It has the characteristics of coarse crystal and good development crystal structure. The plate-like crystal structure has small pores and many closed pores, and the porosity is roughly the same as that of fused corundum. It has high purity, good volume stability and minimal reheating shrinkage.
