White Fused Aluminum Oxide Fine Powde #320F/200F
Fused Aluminium Oxide is a very refractory, hard and chemically resistant material widely
used in the refractory, abrasive and foundry industries.In the investment casting industry,
White Fused Alumina(White Corundum) is recommended as a refractory flour and stucco
for the first coats (equiax process). In single crystal and directional solidification,
Fused Alumina is a standard refractory material for both prime coat and back-ups.
