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.
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.
High purity aluminum oxide is the raw material for sapphire crystal. This type of pressed pellets are made from ultra high purity alumina. It is designed to provide high filling in crucibles used to make sapphire single crystals. The alumina materials RBST supplied are produced with latest eco-friendly and high technology. As a supplier for advanced materials, we continuously improving the service by cooperate with the manufacturers with high efficiency large volume production.
