Laurel Magnesia alumina spinel bricks are high-grade alkaline refractory materials made from high-purity materials with periclase and spinel as the main minerals, which are sintered at high temperatures. At the same time, specific mineralizers are added to directly combine the crystal phase particles of the product. It has high strength, excellent thermal shock stability, and chemical corrosion resistance. It is mainly used in the upper and lower transition zones of cement rotary kilns and thermal kiln equipment that requires high temperature resistance and thermal shock resistance.

Our magnesia alumina spinel bricks feature excellent thermal shock resistance, low thermal conductivity, and high corrosion resistance—perfect for cement rotary kilns and steel furnaces.

Features

Features

Spinel Matrix for Slag Resistance

The magnesia alumina spinel bricks feature a strong spinel bond that slows slag penetration and chemical degradation—ideal for steelmaking and copper smelting environments.

Thermal Shock & Load-Bearing Strength

These magnesia spinel refractory bricks maintain structural integrity under thermal cycling and heavy mechanical loads, reducing the risk of premature failure in furnaces and incinerators.

Cr-Free and Eco-Friendly Composition

Free from Cr⁶⁺, our magnesia alumina spinel bricks meet international safety standards—suitable for operations requiring clean, sustainable refractories.

Consistent Quality and Custom Sizes

Every magnesia alumina spinel brick is produced with tight quality control, ensuring dimensionally accurate, reliable installation. Custom geometries are available on request.
