Detailed Description
Tabular corundum is a kind of pure of firing shrinkage thorough sintering corundum, with crystal bulky, well-developed alpha Al2O3 crystal structure and don't add such as MGO, B2O3 and any additives. Plate crystal plate structure, hole small and closed stomatal more, high purity, volume stability, tiny dead-burned contraction, resistance to the production of material or castable after high temperature treatment has good thermal shock resistance and bending strength.
Performance: Tabular corundum has good heating volume temperature resistance and good thermal shock resistance capacity.
Application: Tabular corundum is a kind of ideal refractory material, which can be used as aggregate function in all kinds of aluminum refractory materials, can also add to other aluminum amorphous refractory materials. Those who fused corundum or white corundum application site can use tabular corundum alternative, and fireproof material performance improved. Mainly used in metallurgy, chemical industry, electronics, ceramics, high temperature furnace, abrasives, etc.
Tabular corundum is pure alumina raw material, the mill, molding, drying, of 1970 degrees Celsius for ultra high temperature vertical furnace rapid heating, cooling and the formation of the density of the crystal, its microscopic phase is flake, called tabular corundum.
Tabular corundum of Morse's hardness is 9, melting point is 1970 Celsius.
