摘要

A cementitious formulation which is self-setting when mixed with water, and which can be cast into monolithic refractory components capable of resisting molten metal and repeated thermal shocks, has three main components: 60-95% of high purity magnesia (at least 94% by weight being MgO); at least 1% of high purity alumina (at least 98% by weight Al2O3) and 4-15% of high alumna cement (preferably 75% Al2O3 by weight, or greater).
