White aluminum oxide (white fused alumina, Al₂O₃) is widely used as a wear-resistant ceramic layer due to its exceptional hardness (Mohs 9), high melting point (~2050°C), and excellent chemical stability.

white aluminum oxide is a versatile performance-enhancing material in the ceramic industry. Its role extends from being a fundamental building block of kilns (refractories) to a defining component of the final product’s strength and surface (body/glaze additive), making it essential for both traditional and advanced ceramic manufacturing.

white fused alumina powder is a versatile, high-performance synthetic material prized for its hardness, purity, and sharpness. Its primary role is as a premium abrasive, but its unique properties make it indispensable in high-temperature industries, precision manufacturing, and advanced composite materials.

White fused alumina (WFA, abbreviated as WA) powder for crucible is produced by melting high-purity industrial alumina powder at 2050–2200 °C in an electric arc furnace. After crystallization, crushing, iron removal by magnetic separation and particle classification, α-Al₂O₃ crystalline powder is obtained

White Fused Alumina (WFA / WA) Powder is made from high-purity industrial alumina, fused and crystallized in an electric arc furnace at over 2000°C. Its main crystalline phase is α-Al₂O₃. It is a high-performance rigid functional filler specially formulated for industrial coatings, featuring ultra-high purity, high whiteness and a full range of fine particle sizes.
