white fused alumina (WFA) micro powder is available in spherical forms, which are categorized into two main types based on production processes and roundness, each suitable for different applications and cost considerations. Spherical Types and Production Processes Near-spherical/quasi-spherical WFA micro powder: Produced via autogenous grinding shaping or jet milling. It has a moderate roundness (0.7–0.8)

White fused alumina micro powder is not available in a flat form as a standard product. Its production process—melting high-purity alumina in an electric arc furnace, followed by cooling, crushing, shaping, and classification—results in angular, blocky, or near-spherical particles rather than flat, plate-like crystals. For flat/plate-like alumina micro powder, you should opt for tabular alumina fine
