The Description of Tabular Alumina:
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.
The Application of Tabular Alumina:
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.
