Mullite Brick: Versatile High-Temp Refractory for Multi-Industrial Kilns

TY Refractory’s premium Mullite Brick takes mullite as the core mineral phase, controlled with 65%-75% Al₂O₃ content to form stable interlocking crystal structures. Every Mullite Brick delivers reliable high-temperature strength and remarkable thermal shock resistance, resisting cracking during frequent temperature fluctuations inside industrial furnaces.

This industrial-grade Mullite Brick boasts stable technical indexes: bulk density 2.6–3.0 g/cm³, cold crushing strength ≥40 MPa and refractoriness above 1650°C, with a sustainable working temperature up to 1700°C. The compact matrix of each Mullite Brick offers outstanding chemical inertness, standing erosion from acidic slags, oxidizing furnace atmospheres and volatile corrosive gases, avoiding premature lining peeling.

The multi-scenario Mullite Brick serves diverse industries: blast furnace bottoms, hot blast stove roofs, glass furnace regenerators, lime kilns, petrochemical reactors and ceramic high-temperature kilns. Custom sizes and tailored formulations of Mullite Brick are available to match various furnace lining structures.

Backed by over 20 years of refractory manufacturing, our factory holds complete ISO triple certifications and 21 technical patents. Strict full-batch lab tests guarantee consistent quality of all Mullite Brick products. Global manufacturers select our Mullite Brick to extend furnace service cycles and cut regular maintenance expenses.
