- SiO2 (Silica): 5-10%
- Fe2O3 (Iron Oxide): <0.5%
- Other oxides: trace amounts
This mix delivers excellent chemical stability, making the bricks highly resistant to corrosion from slag and gases, perfect for demanding environments like glass kiln lining or blast furnace bottoms.
Physical and Mechanical Properties
Designed for the toughest jobs, our Corundum-Mullite Bricks offer:
- Refractoriness (service temperature): 1750°C and above
- Cold Crushing Strength: 80-120 MPa
- Apparent Porosity: 12-16%
- Bulk Density: 3.4-3.6 g/cm³
- Thermal Expansion: low and uniform
- High resistance to creep under prolonged high temperatures
These properties ensure long service life with minimal wear, critical for industries requiring thermal shock resistant refractory materials.
Industry Standard Comparison
Our bricks meet or exceed ASTM C71 and ASTM C170 standards for high alumina refractories. Compared to regular high alumina refractory bricks, Gotrays’ Corundum-Mullite Bricks show:
- Superior thermal shock resistance
- Better erosion and corrosion resistance against aggressive slags

Choosing Gotrays Corundum-Mullite Bricks means you’re investing in reliable, high-performance refractory solutions built for U.S. industries demanding toughness and efficiency.
Advanced Manufacturing Process at Gotrays
At Gotrays, making our Corundum-Mullite Brick starts with carefully selecting and blending high-quality raw materials. This step ensures the perfect balance of alumina and mullite for consistent strength and durability.
Next, we use hydraulic molding to shape the bricks with precision. This method guarantees tight compaction, reducing porosity and improving performance under high heat.
Our bricks go through a high-temperature sintering process, where they’re fired at extreme temperatures. This solidifies the structure and boosts resistance to thermal shock, erosion, and high-temperature creep.
Quality assurance is a priority at every step. We test each batch rigorously to meet industry standards and client expectations ensuring you get a reliable product every time.
We also offer customization using CAD design tools. This means we can tailor brick sizes and shapes to your specific furnace lining needs, providing a perfect fit for your operation.
