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.

Introduction of 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 MgO and B2O3. It has the characteristics of coarse crystal and good development �±- Al2O3 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. The refractory or castable used for production has good thermal shock stability and bending strength after high-temperature treatment
Application scope of Tabular Alumina:
Tabular corundum can be used as the main component in aluminum carbon, aluminum magnesium carbon, magnesium aluminum carbon, magnesium spinel and aluminum chromium refractory bricks, and can also be introduced into high aluminum amorphous refractories as enriched alumina. It can be widely used in iron and steel, casting, ceramics and other industries. Its application in iron and steel industry almost covers the whole process of ironmaking and steelmaking.

Tabular Alumina, with the purity, do not add any additives, and firing contraction completely finished sintered alumina, alumina powder as raw material, after fine grinding, molding, drying, for ultra high temperature furnace with the temperature below the melting point of corundum, quick heat cooling fast under the condition of burning, to form a number of closely with columnar crystal, with high purity,high melting point, grains high hardness, heat load of high strength, low shrinkage, high density and low permeability, good wear resistance, good thermal shock stability etc. Tabular Alumina Usage Specification Chemical composition Bulk Density gcm3 Apparent Porosity Al2O3 Na2O Fe2O3 SiO2 Refractory Size 0 1mm 1-3mm 3-5mm 5-8mm 99.0 0.35 0.2 0.2 3.5 5.0 Fine 200 0 325 0 98.5
