Calcined Alumina, Purity : 99.6

We offer calcined alumina.
�main uses
�refractory materials.about 80% of calcined alumina is used as refractory components.calcined alumina is used to product refractory brick,the whole piece of refractory material and cast refractory materials,high alumina content of calcium aluminate cement.it has the characteristics of heat resistence,heat shock resistence and dimensional stability.
�ceramic.in the production of high strength of alumina ceramics,transparent ceramics and special ceramics,the clay joined calcined can improve the strength of the ceramic and mechanical stability.to improve the durability,it is used in the production of wall and floor tiles,porcelain tableware.this kind of ceramic can be made of cutting,calendering products,wire guide,ball valve,sealing ring,radar window,etc.and also can be used as bioceramic instead of part of the bone,insulation materials in the high tension line,spark plugs,etc.it is widly used in coating,rubber,plastic reinforced material,the precision is wearable materials,etc.
