Features

Features

Optimized Mullite Crystal Structure

Each jm/gm series mullite brick features a well-formed mullite phase, providing excellent resistance to thermal deformation and minimizing expansion under heat cycling. Similarly, b/c series mullite bricks excel in structural stability and load support at elevated temperatures.

High-Temperature Creep and Thermal Shock Resistance

Whether in static or dynamic furnace zones, these mullite refractory bricks offer superior creep resistance and thermal stability. Ideal for upper and middle zones of kilns and regenerative furnaces.

Low Thermal Conductivity & High Strength

Engineered with low bulk density, the jm/gm and b/c series mullite bricks effectively reduce heat loss while maintaining strong mechanical integrity—making them suitable for both hot-face and backup applications.

Competitive Mullite Refractory Bricks Price

Laurel ensures value by offering high-performance mullite refractory bricks at favorable price points, supporting both small-scale and large industrial operations.
