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.

White Fused Alumina Powder for Glass Polishing White Fused Alumina (WFA / White Corundum) Main component: α-Al₂O₃ ≥ 99.0% (high-purity fused alumina melted above 2000℃ in electric arc furnace) Mohs hardness: 9.0. White fine powder, low iron, low silica, minimal staining risk on glass Also named white aluminum oxide polishing powder / white corundum micro-powder

White fused alumina micropowder is a workhorse in the precision lapping industry. It offers an excellent balance of cutting efficiency, controllable surface finish, and cost-effectiveness. Its high purity, angular morphology, and controlled friability make it the go-to choice for a wide range of applications, from preparing metal specimens for metallography to finishing critical semiconductor and optical components.

white aluminum oxide powder is an indispensable functional material for modern precision manufacturing, advanced materials, and high-temperature industries. Its applications span from traditional finishing processes to cutting-edge fields like semiconductors, aerospace, and advanced ceramics.
