Made from high purity magnesia (low impurty,C/S≥2)and high-grademagnesia alumina spinel, so it gives excellent high temperature performanceand excellent resistance against chemical attack. Higher spinel contentimproves flexibility and thermal shock resistance. Therefore, it is suitable to beused in transition zones of cement rotary kiin. Cement kiins in Europe widely usealternative fuels which bring about severe chemical erosion, large hightemperature area, frequent temperature fluctuation, and frequent conversionbetween oxidizing and reducing atmosphere in the kiln and our magnesia alumina spinelbrick has achieved good perforance in the transition zone and buming zone.
