Product Overview

Our Premium High-Alumina Mullite Silica Refractory Tiles represent cutting-edge advancement in aluminosilicate refractory technology. These precision-engineered tiles are manufactured from premium synthetic mullite and high-purity alumina, creating an optimal balance of thermal stability, mechanical strength, and chemical resistance.

The unique crystalline structure of mullite (3Al₂O₃·2SiO₂) provides exceptional dimensional stability and resistance to thermal shock, whilst the high alumina content ensures superior performance at elevated temperatures. Our manufacturing process incorporates advanced sintering techniques to achieve optimal microstructure and consistent quality.

Available in four distinct grades (LSM-75, LSM-70, LS-65, LS-60), our tiles offer tailored solutions for diverse industrial applications, from glass furnace superstructures to steel industry heating systems. Each grade is optimised for specific temperature ranges and chemical environments.
