PURPOSE:To obtain an alumina-magnesia refractory having improved slag- infiltration resistance, corrosion resistance and spalling resistance and to prolong the life of a container or apparatus made of the refractory by compounding two kinds of magnesia having specific purities and particle diameters to an alumina used as a main material at specific ratios. CONSTITUTION:The objective refractory having excellent slag-infiltration resistance, corrosion resistance and spalling resistance is composed of 2-10% magnesia having particle diameter of <=0.15mm and an MgO purity of >=97%, 1-30% magnesia having particle diameter of >=0.3mm and an MgO purity of >=90% and the remaining part of alumina. |
