In order to study the characteristic properties of fired high Al2O3 ceramics formed by injection molding their physical, mechanical, and electrical properties were compared with those of the same composition but formed by pressing and casting.The conditions of processing whose variation being least influential on the properties of the fired articles were:(1) Composition, Nonplastic ceramic material 81.7%Polystyrene 12.3%Stearic acid 4%D. E. P. plastizer 2%(2) Pressure 1000kg/cm2Temperature of the mixture 140°CTemperature of the mold 40°CSome properties of the articles formed by injection molding, i.e., mechanical strength, coefficient of thermal expansion, specific gravity were in the same level with those formed by conventional means, i.e., by pressing or casting.The author concluded that the process of injection molding may be applied to the production of the various kinds of articles such as high grade insulators, ceramic cutting tools, etc.
