White Fused Alumina
Al₂O₃
High-purity white fused alumina supplied for precision abrasives, advanced refractories, and electronics-grade ceramic applications.
Overview
White fused alumina (WFA) is produced by fusing high-purity calcined alumina in an electric arc furnace, yielding >99% Al₂O₃ purity with exceptional hardness, friability, and chemical purity. Compared to BFA, WFA has higher purity and is preferred in precision grinding, advanced refractories, electronics ceramics, and pharmaceutical polishing.
