Tabular Alumina uses industrial alumina as the raw material, and is sintered in high-temperature vertical kiln with a temperature greater than 1900℃.The product is made of granular corundum crystals closely arranged, evenly
distributed to each other, to achieve the best density and inter-granular strength. With high purity, low alkali, high strength, high thermal shock resistance, corrosion resistance properties, it mainly used as alumina base and
alumina containing refractory bone material and substrate.
It is widely used in metallurgical refractory materials (slide, nozzle, porous plug brick, etc.),ceramic, chemical, glass, abrasives and other industries with refractory materials figured.
