Alumina Bricks

Alumina Bricks Manufacturers & Suppliers in India

Alumina Bricks, chemically classified under high-alumina refractory blocks, are dense, high-temperature fired blocks widely used as a core lining material across industrial kilns, furnaces, reactors, and thermal vessels. Produced through the controlled shaping, pressing, and high-temperature firing of premium bauxite, mullite, and synthetic alumina aggregates, they yield a high-purity, structurally stable product with exceptional load-bearing capacity under extreme heat.

Due to its exceptional thermal stability and versatility, Alumina Bricks are vital for heavy industries, iron and steel plants, cement kilns, and glass manufacturing furnaces. Industrial refractory suppliers in India provide high-grade Alumina Bricks that ensure consistent quality, reliable sourcing, and industrial compliance for professional use.

High Alumina Bricks Specifications

Manufactured for heavy-duty refractory environments, our High Alumina Bricks feature an Al₂O₃ content of 68% to 70% with low iron levels kept at 0.5% Fe₂O₃ max to ensure high thermal resistance and prevent chemical erosion. Boasting a dense bulk density of 3.4 g/cc and a controlled apparent porosity limited to 8.0% max, these bricks deliver exceptional cold crushing strength, superior resistance to slag penetration, and high load-bearing capacity under extreme service temperatures.
