Abstract
In order to obtain periclase-spinel refractories of high quality it is necessary to use chemically pure magnesite and chromite powders, and also high firing temperatures. In the high-fired periclase-spinel refractories made from these powders a quantitatively new structure is formed: the direct bonds between the crystals of periclase and chrome spinel predominate (more than 50%). The secondary spinels, fulfilling the role of bond in the grains of periclase, possess a high melting point.
