White Fused Alumina (WFA) 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 2000°C followed by a slow solidification process.
Strict control over quality of raw materials and fusion parameters ensure products of high purity and high whiteness, high hardness, excellent self-sharpening, and acid/alkali resistance with good thermal stability.
