Introduction
White Fused Alumina (WFA) is obtained from the fusion of high purity calcined alumina in electric arc furnaces. WFA is raw material characterized with white color, high hardness, high density, low porosity, highly resistant to heat and abrasion, chemical stability, a high melting point, and large crystal size.
