White fused alumina
White fused alumina
White Fused Alumina is made from the high quality alumina by melting above 2000 ℃ in the electric arc furnace and cooled into ingots, crushed and then classified, it is white with the main crystal phase α- Al2O3, white fused alumina has advantage of high bulk density and low porosity, then the volume stability and thermal shock resistance can be improved.
