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 powder, which is produced via low-temperature sintering and recrystallization to form interlocking plate-shaped crystals with high density and low thermal expansion. It can be ground to micro-powder sizes (e.g., 325 mesh) and is primarily used in refractory applications, unlike white fused alumina, which is better suited for grinding, polishing, and abrasive tools.
If you need flat alumina micro powder for specific uses like grinding/polishing or refractory materials, specify the particle size and application, and I can recommend the right product and supplier options.
