Abstract
A refractory mix and resultant shapes formed by burning the mix, the mix comprising a magnesia-alumina spinel grain containing at least 27% MgO by weight, a fused magnesite grain, and up to 10% by weight alumina, it being possible to substitute a sintered magnesite grain for up to 50% by weight of the fused magnesite grain.
