Product Introduction-WFA factory fused alumina china manufacturer
refractory white corundum was made from the high quality alumina powder by melting above 2000°C in the electric arc furnace and cooling.
WA refractory white corunduma is white with the main crystal phase alphaAl2O3.
WA refractory white corundum 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.
Model&Application-WFA factory fused alumina china manufacturer
