PURPOSE:To provide a method for molding a complicated-shape graphite- dispersing ceramic molding of high density with high dimensional accuracy by using a thermosetting resin prepolymer as a molding binder. CONSTITUTION:A mixture composed of a thermosetting resin prepolymer as a molding binder and a powdery ceramics in a volume ratio of (30:70) to (5:95) is molded in a mold at the flow point of the prepolymer and organic materials contained in the resin are subsequently decomposed in an inert gas and then sintered in an inert gas to obtain the objective graphite-dispersing ceramic molding. Use of the thermosetting resin prepolymer enables use of a solvent for mixing the ceramic raw materials therewith and, therefore, uniform blending. By decomposition of the thermosetting resin, graphite remains in the sintered material and thereby a sliding effect is exhibited. |
