PURPOSE:To obtain a composition having excellent kneading properties, fluidity and degreasing properties and free from occurrence of crack in the product after degreasing and burning by blending a ceramic material with an organic binder main agent and higher fatty acid ester of polyhydric alcohol. CONSTITUTION:The ceramic composition containing (a) ceramic material, (b) organic binder main agent and (c) higher fatty acid ester of polyhydric alcohol of 0.1-5pts.wt. based on 100pts.wt. ceramic material (a). The preferred organic binder main agent (b) includes at least one kind of resin among atactic polypropylene, polystyrene and ethylene-vinyl acetate copolymer, polybutylmethacrylate and wax. The organic binder main agent (b) is used at an amount of 12-38pts.wt., preferably 16-27pts.wt. based on 100pts.wt. ceramic raw material. |
