AZS Cullet

AZS Cullet Manufacturers & Suppliers in India

AZS Cullet, chemically known as Alumina-Zirconia-Silica (Al₂O₃-ZrO₂-SiO₂) recycled scrap or crushed aggregate, is an off-white, exceptionally dense, crystalline material widely used as a core secondary raw material across high-performance refractory, ceramic, abrasive, and metallurgical applications. Produced through the controlled sorting, cleaning, and crushing of premium fused-cast AZS furnace blocks (typically categorized by zirconia content like AZS 33#, 36#, or 41#), it yields a high-purity, thermally stable recycling material with exceptional crystalline hardness.

Due to its exceptional thermal stability and versatility, AZS Cullet is vital for heavy industries, glass melting tank furnace linings, specialty monolithic castables, and steel manufacturing rams. Industrial mineral recycling networks and refractory suppliers in India provide high-grade AZS Cullet that ensures consistent quality, reliable sourcing, and industrial compliance for professional use.

AZS Cullet Specifications

Engineered for ultra-high temperature applications and aggressive corrosion resistance, our AZS Cullet features a high alumina purity of 95% to 98% Al₂O₃ with exceptionally low iron impurities restricted to 0.50% Fe₂O₃ max. It delivers a dense bulk density of 3.4 g/cc alongside an apparent porosity kept under 8% max, ensuring outstanding structural integrity, minimal thermal expansion, and strong resistance to glass melt erosion. Available in uniform grain sizes (0–1 mm, 1–3 mm, and 3–5 mm), it is an essential raw material for formulating fused cast refractories, specialty mortars, glass furnace linings, and heavy-duty thermal applications.
