Product Description:
White fused alumina,a kind of high-grade refractories,is made from the imported high quality alumina by melting above 2000ºC in the electric arc furnace and then cooling.It's white color with the main crystal phase alpha -Al2O3.The WFA produced in the titling electric arc furnace has the advantage of high bulk density and low porosity,thus the volume stability and the thermal shock resistance can be improved.
