text: It is another advantage that shapes so prepared of admixtures of magnesia with, for example, alumina, while excessively refractory for burning in a 1rgltary kiln, are suitable for processing to spinel in a stack In the process of this invention the starting material, which may be magnesia, or magnesia admixed with silica, alumina, titania, zirconia or other refractory-producing material, is shaped with the addition of water, preferably under pressure as by extrusion through a die and cut to form pellets of desired length, and allowed The hardening eifect is accompanied by considerable evolution of heat, developed by the hydrating reaction, and, if desired, the shapes can be cooled during the hydrating step.
