Features

Features

In-Situ Mullite Transformation

Under firing conditions, sillimanite transforms into mullite and free silica, enhancing the mechanical properties and longevity of sillimanite refractory bricks. This dense crystalline structure contributes to excellent slag resistance and high mechanical strength.

Low Thermal Expansion & Superior Shock Resistance

Thanks to low thermal expansion, sillimanite bricks remain structurally intact during repeated heating and cooling cycles—ideal for furnaces, kilns, and incinerators with fluctuating temperatures.

Corrosion Resistance Against Acids and Alkalis

These sillimanite refractory bricks offer excellent durability against acid slags and alkali vapors, ensuring extended performance in non-ferrous metallurgy, petrochemical reactors, and glass processing.
