Exceptional Material Properties

Mullite Brick is a high-alumina refractory product primarily composed of mullite (3Al2O3·2SiO2). Available in both sintered and electric-melted forms, it is manufactured using synthetic mullite clinker and high-alumina bauxite clinker. Following a process of blending, high-pressure forming, and firing at temperatures exceeding 1600℃, we create an exceptionally durable product.

Outstanding Advantages of Mullite Brick

The unique composition of Mullite Brick leads to several noteworthy advantages:

• High-Temperature Resistance: With firing temperatures over 1600℃, these bricks maintain excellent thermal stability and deformation resistance.
• Thermal Shock Stability: They demonstrate remarkable resistance to thermal shock, retaining integrity even under significant temperature fluctuations.
• Low Creep Rate: Designed for high-stress conditions, they boast a low creep rate, ensuring consistent shape and performance.
• Corrosion Resistance: They exhibit strong acid slag corrosion resistance, making them suitable for various corrosive environments.

Diverse Applications

Mullite Brick is ideally suited for use across multiple industries:

• Blast Furnaces: Perfect for linings in industrial kilns operating at temperatures exceeding 1200℃.
• Steel Industry: Integral in components such as torpedo cars, slag lines, and electric arc furnace roofs.
• Ceramics and Glass: Essential for the structure of heat-retaining chambers in ceramic kilns and glass melting furnaces.

Discover how Mullite Brick can meet your high-temperature needs and enhance your production efficiency in the iron, steel, ceramics, and glass industries.
