Features

Features

Superior Resistance to Basic Slags

Our high purity magnesia brick features 88–96% MgO content, delivering unmatched protection against lime-rich and iron-bearing slags common in EAFs, rotary kilns, and BOFs.

Thermal Stability Beyond 1700°C

With excellent refractoriness under load (≥1700°C), these magnesia bricks for sale maintain form and function under continuous thermal stress, ensuring consistent lining performance.

Low Porosity, Dense Structure

High-temperature sintered or electrofused, each high purity magnesia brick features a tight grain microstructure and ≤17% apparent porosity, minimizing slag/gas infiltration.

Available at Wholesale & Custom Specs
