Features

Features

Flexible Alumina-Silica Composition for Targeted Efficiency

Each refractory high alumina brick contains an optimized balance of Al₂O₃ (48%–85%) and silica, ensuring reliable operation across diverse industries—from cement kilns to steel melting units.

High Resistance to Slag and Chemical Erosion

Engineered with elevated alumina levels, these high alumina silica bricks offer exceptional resistance to both acidic and basic slags, as well as alkali vapor corrosion common in cement and glass production.

Low Porosity and Dense Microstructure

Our refractory high alumina brick line features low apparent porosity, minimizing molten infiltration and extending service life in continuous-use furnace environments.

Cost-Effective with Consistent Quality

With Laurel, customers benefit from durable refractory solutions and a competitive high alumina bricks price, making them suitable for both large-scale installations.
