    • In the injection molding process of ceramics, an injection mold having an area of the gate of at least 20% of the maximum cross-sectional area of the cavity viewed from the gate side is employed. The gate preferably has a shape substantially similar to a projection of the cavity viewed from the gate side. Further, the temperature of the mold is preferred to be controlled to have a temperature gradient in such a manner that the distribution of temperature of the molded body in the vicinity of the mold is brought into the range of .+-.0.5.degree. C. about a setting temperature, at the time pressurization of the molded body in the mold has just been completed. According to the process of the invention, the molding material injected and passed through the gate is controlled to flow smoothly along the shape of the cavity, uniformly purging the air so that homogeneous molded bodies free from defects, such as pores, weld-marks, or the like, can be obtained.
