white fused alumina sand 3-5mm for refractory material

Product Introduction

White fused alumina was made from the high quality alumina by melting above value="2000" tcsc="0" unitname="ﾰC" w:st="on">2000°C in the electric arc furnace and cooling. It is white with the main crystal phase alphaAl2O3.

White fused alumina produced intitling electric arc furnace has the adwantage of high bulk density and low porosity and the volume stability and thermal shock resistance  can be improved.
