Low Sodium White Fused Alumina Blocks 99.55% High thermal stability
Tilting Furnace Barmac Crushed White Fused Alumina WFA for Mouldable and Ramming Refractory Products
1. White Fused Alumina Descriptions
White Fused Alumina is produced by fusion of high purity Bayer processed alumina in electric arc furnaces at a temperature of about 2,050 degree Celsius. JCT’s white fused alumina has the features of well-distributed particle size composition, low magnetic substance content, high bulk density and toughness, good toughness, and high cleanliness, etc. The bonded abrasives made by white fused alumina are recommended for the grinding of high carbon steel, high speed steel and chilled steel. It can also be used as blasting, lapping and polishing media and laminating flooring materials.
2. White Fused Alumina Characteristics
1. High hardness and High purity;
2. High thermal stability and Stable chemicals;
