WTA Manufacturers & Suppliers in India
White Tabular Alumina (WTA), chemically classified as a high-purity, fully shrunk alpha-alumina crystalline aggregate, is a white, dense, granular or powdered material widely used as a core raw material across high-performance refractory, ceramic, electrical insulation, and investment casting applications. Produced through the controlled thermal processing and ultra-high-temperature sintering of calcined alumina without adding any additives at temperatures exceeding 1800°C, it causes the alpha-alumina crystals to grow into large, tabular-shaped hexagonal crystals, yielding a high-purity (typically >99% Al₂O₃), thermally stable material with exceptional structural compactness.
Due to its exceptional thermal stability and versatility, White Tabular Alumina WTA is vital for heavy industries, steel ladle refractories, purge cones, slide gates, high-end monolithic castables, and advanced technical ceramics.
