Compositions for forming carbon-containing refractory brick or shape comprising a refractory filler, a binder for said filler and a hardening agent for said binder, said binder comprising a mixture of polymers formed by the homopolymerization of resorcinol. Compositions for forming a carbon-containing refractory brick or shape as above described are also disclosed in which a basic refractory filler is employed and hardening agents are unnecessary. Methods of forming carbon-containing refractory brick or shape are also disclosed involving milling of a dry binder comprising a mixture of polymers formed by the homopolymerization of resorcinol with the refractory filler or mixture of a solution of such a binder material with the refractory filler, either of which may be conducted at ambient temperature.

Use of resorcinal polymer blend as a binder for carbon-containing

A non-aqueous, thermoplastic refractory binder comprising a resinous petroleum residue having a softening point ranging from 100.degree. F. to 150.degree. F. (38.degree.-65.degree. C.), being less than 2% insoluble in benzene, and preferably having a fixed carbon content of between 30 and 40%, and refractories made therewith.
