ABSTRACT:
Thermosetting refractory compositions which require no drying are obtained from unpolymerized unsaturated polyesters and cross-linking vinyl monomers and desired refractories together with mold release materials. Organic fillers may be included to give more porous fired refractories. Danger of blistering of the thermoset shape on firing is counteracted by a volatile material which forms a reticulum of capillaries in the thermoset shape. Compositions may be used for extrusion, molding or injection, thermosetting occurring simultaneously or subsequently.
