Platelet Alumina is a high quality alumina type abrasive powder,

White aluminum oxide (Al₂O₃) powder is an excellent choice for

White fused alumina lapping powder remains the industry-standard workhorse for a vast range of precision finishing applications.

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.

Industrial grade WFA (Al₂O₃ ≥99.0%, Na₂O 0.20%–0.40%) is the most common economical grade, widely used in abrasives, refractories, sandblasting and ceramic industry

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.
