White Aluminum oxide 1) High AL2O3 content: 99.5%min 2) manufacturer over 10 years 3) ISO9001 4) JIS,FEPA,ANSI standards
Manufacturer Fused White Aluminum oxide for refractory grade
White fused corundum, a kind of high-grade refractories , was made from the high quality alumina
by melting above 2000 in the electric arc furnace and cooling.It is white with the main crystal phase
alphaAl2O3.The white alumina produced in titling electric arc furnace has the advantage of high bulk
density and low porosity and the volume stability and thermal shock resistance can be improved.
