at the temperature of above 2000 ℃ in the electric arc furnace.It has the properties of big bulk density, good thermal shock stability and strong anti-erosion. It is an ideal material for production of high-grade magnesia-alumina brick, high performance magnesia-alumina castable, large cement kiln etc.
