Magnesia-Alumina Spinel refractory refractory brick High temperature high refractoriness refractory materials Magnesia Spinel Brick

Product Description

Magnesia-alumina spinel brick is a high-performance refractory material with magnesia-alumina spinel (MgAl₂O₄) as the main crystalline phase, combining the advantages of magnesia and alumina refractories.

Feature

Excellent thermal shock resistance, with low tendency for spalling.
Strong resistance to alkali, sulfur, and corrosion.
High high-temperature strength and good volume stability.

Typical Application

Commonly used in transition zones of cement rotary kilns, ladle linings, waste incinerators, and other high-temperature equipment requiring excellent thermal shock resistance and erosion resistance.
