This low sodium Calcined alumina presents in a white powder or granulated sugar shape,the crystal structure is stable. It is featured with low sodium oxide content, high chemistry purity. It can not dissolve in the water and difficult to dissolve in the acid and alkali solution. This product has good stable performance, easy to be grinded and sintered.
This low sodium Calcined alumina is the ideal raw material of the high temperature fire-proof material, the pouring casting, the electric porcelaneous component, the spark plug, the high alumina ceramic, the wear resistant ceramic and electronic substrate product. Besides, it is widely used in the grinding and the polishing profession.
