PROBLEM TO BE SOLVED: To provide a novel compsn. and sintered compact having decreased defects and having a high commercialization rate. SOLUTION: This compsn. for injection molding of inorg. powder is composed of the inorg. power, 3 to 30 pts.wt. ethylene-vinyl acetate copolymer per 100 pts.wt. inorg. powder and 1 to 30 pts.wt. and at least one kind among glycerol fatty acid ester wax, sorbitan fatty acid ester wax, polyglycerol fatty acid ester wax and propylene glycol fatty acid ester wax per 100 pts.wt. per inorg. powder. The compsn. has excellent moldability, degradability and sinterability and the final sintered compact having the high manufacturing rate may be provided. Remarkable effects are admitted. |
