ABSTRACT:
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.
