The magnesite alumina brick is a kind of high quality basic refractory.
It contains 7-9% Fe2O3, very small content of SiO2 and CaO,and small content of Cr2O3.The series of high alumina brick feature excellent high temperature mechanics and chemical corrosion resistance to acid and alkali basic solution. They were widely used in metallurgy, petroleum, chemistry, etc.
