Description

white fused alumina is made from excellent industrial alumina and melted in arc furnaces

 

at high temperature of 2050°C. It is featured by high purity, good self-sharpening, low

 

grinding heat output, acid-alkali and corrosion resistance, good stability at high temperature,

 

and low porosity, etc.
