Characteristics of Spinel Bricks

Strong Alkaline Erosion Resistance: Magnesia alumina spinel brick is an alkaline material. It can resist alkaline erosion in high-temperature situations. So it is usually used for the linings of industrial equipment that have alkaline substances or solutions production.
Good Resistance to Peeling: Magnesia spinel bricks have higher refractoriness than magnesia bricks. Magnesia alumina spinel brick can undertake more than 50MPa. So it can resist high-temperature and high-pressure environments. It is used for the linings of kilns or vulnerable parts.
Great Thermal Stability: Magnesia alumina spinel bricks have a stable structure. The under load temperature can be up to 1600℃. They can resist extreme thermal shock that will not crack or damage. So they can sustain a steady state of high-temperature equipment.
Low Thermal Conductivity: The low thermal conductivity contributes to having a good insulation ability. Magnesia alumina spinel brick can effectively improve the energy utilized that reduce heat transfer. So it can be used for linings of furnaces.
