99.5% White Fused Alumina F20-F180
PRODUCT: White Fused Alumina
NAME: White Fused Alumina
Al2O3 CONTENT: 99.5% MIN.
DESCRIPTION:
White Fused Alumina 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 alpha-Al2O3.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.
