Tabular Alumina
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.
