Barmac Crushed White Fused Alumina WFA high purity For Monolithic
Tilting Furnace Barmac Crushed White Fused Aluminum Oxide WFA for Monolithic Refractories
1. White Fused Alumina Descriptions
White Fused Alumina is a high purity, synthetic mineral, manufactured by the fusion of controlled quality pure grade Bayer Alumina in an electric arc furnace at temperatures greater than 2000oC followed by a slow solidification process. Strict control over quality of raw materials and fusion parameters ensure products of high purity and high whiteness.
