Chromium intermediates subsidiary sixth group in the periodic table, and generally has a high melting point, strength and corrosion resistance are good. So far for the production of chromium carbide method such as a metal chromium and chromium oxide Krbvrh reaction, melting and rapid cooling and process My¬Shd use mixtures that require high temperature and long time. Studied methods for the production of carbide in this study, including three mechanical activation of mechanical, combustion by microwave synthesis and microwave synthesis combustion by mixing powder activated by mechanical activation, is. X-ray diffraction, the characterization of the material produced was done. During the 10 hours of mechanical activation and severity rpm300 chromium oxide was revived by magnesium, chromium metal and chromium metal in more than 16 hours, but not the formation of chromium carbide. It also produces chrome rpm300 was more than that in rpm600. The third method of performing combustion synthesis is activated by microwave on the powdery mixture. In this way, mechanical activation in the time period of 10, 30 and 60 minutes and ten hours and was carried out with an excess of magnesium was rpm300 intensity, then microwave operation took place, the survey results were observed with increasing time MgCr2O4 low intensity is an unwanted compound so that this compound is completely eliminated in 10 hours is an increased amount of chromium carbide.
