1.Brief Introduction White Fused Alumina is made from the high quality alumina bymelting above 2000 in the electric arc furnace and cool down. It is white withthe main crystal phase alpha-Al2O3.It has the advantageof high bulk density and low porosity and the volume stability and thermalshock resistance.
