Features

Balanced Resistance to Chemical Attack

The interlocking crystal matrix of magnesium oxide and chromium oxide enhances corrosion resistance in direct bonded magnesia chrome brick, effectively withstanding acidic and basic slags in multi-fuel operations.

Superior High-Temperature Strength

Even at 1700°C, our magnesia chrome bricks for sale offer excellent mechanical strength and thermal integrity—ensuring fewer shutdowns and longer campaign life.

Reliable Thermal Shock Stability

Designed for operations with frequent heating/cooling cycles, each direct bonded magnesia chrome brick resists spalling and cracking through enhanced grain-boundary bonding and thermal flexibility.

Dense Microstructure

Low porosity limits slag infiltration, maintaining surface integrity even in highly oxidizing environments. This property stabilizes magnesia chrome bricks price by reducing relining frequency.

Custom Options Available

Our product line includes various sizes and shapes, including customized direct bonded magnesia chrome brick types with higher Cr₂O₃ content, meeting exacting furnace specifications.
