| White Fused Alumina for Refractory |
White fused alumina (WFA) is a raw material for production of refractories material. It also called white corundum or white aluminum oxide. Comparing with the Brown fused alumina, it is more homogenous in terms of chemical composition, structure and properties. The result is a product with high hardness, high friability, high purity, high melting point, and large crystal size. It widely used in refractory industry, also can be used in ceramics shapes, grinding wheels, sandpaper, blasting media, metal preparation, laminates, coatings, lapping, polishing, grinding and hundreds of other applications.
| Features |
● White fused alumina (WFA) is made from high quality aluminium oxide powder / alumina powder which melted point above 2200℃
● It has high hardness, high friability, high purity
● With the fine thermal stability of White fused alumina, it can be used for hook refractory material, refractory castables and other refractory materials.
