PROBLEM TO BE SOLVED: To obtain a composition, reduced in the change in concentration of a compound upon deaeration, long in pot life, and capable of manufacturing a molded form, reduced in deformation due to the change in volume and prominent in strength. SOLUTION: A compositor for injection molding is constituted of inorganic powder and organic binder while the organic binder is liquid at a temperature upon solidifying the compound for injection molding in a shaping mold and contains 10-70vol% of organic constituent having a vapor pressure of 1mmHg or less at a normal temperature to 150 deg.C. Especially, butyl stearate is employed as the organic constituent. |
