1.Brief Introduction
White Fused Alumina is made from the high quality alumina by melting above ***0 in the electric arc furnace and cool down. It is white with the main crystal phase alpha-Al2O3.It has the advantage of high bulk density and low porosity and the volume stability and thermal shock resistance.
 
Product Classification        Model NO.
