WFA White Fused Alumina Grains 8-5/5-3/3-1/1-0mm

WFA White Fused Alumina Grains 8-5/5-3/3-1/1-0mm White fused alumina refractory grain is made from high purity Bayer process alumina. Raw materials and furnacing practices are carefully controlled to ensure the highest purity and optimum crystal structure. It is crushed in such a manner to produce blocky grain distributions with a higher bulk density.
