Abstract

A magnesia refractory comprising grains of crystalline magnesia coated and cemented together by a material consisting chiefly of forsterite is formed by firing a mixture of coarse grain of sintered magnesite and finely divided silica in such proportions that the silica can combine with part of the magnesia to form forsterite. In an example, 100 parts of deadburnt crystalline magnesia crushed to pass a 6 mesh screen but with 50 per cent retained on a 100 mesh screen (U.S.A. Bureau of Standards) and 14 parts of silica flour are dry mixed, tempered in a wet pan, moulded, and fired between 3100 and 3450 DEG F.
