An electric contact material of silver-iron oxide was prepared from mixed silver-iron electrolytic powder and mixed Ag-Fe2O3-Fe3O4 precipitates by powder metallurgical process. The compact was sintered in the atmosphere of mixed CO-CO2 gas and the sintering behaviour of the silver-iron oxide compact was investigated by means of X-ray diffraction analysis and measurement of electrical properties of the sintered specimens. As the result, the optimum compacting pressure, gas composition, sintering temperature and sintering time for electrolytic powder system were determined respectively as follows: Below 1 t/cm2, \dfracCOCO+CO2 30∼35%, 850∼890°C, 3/4 to 1 hour re-pressin at 5 t/cm2 followed by 3 hour repressing, for precipitate powder system; about 4 t/cm2, \dfracCOCO+CO2 50∼60%, 850∼890°C, 3/4 t/hour re-pressing at 5 t/cm2 followed by 1\dfrac12 hour re-pressing, for precipitate system.
