Fabrication of intermetallics foam by combustion synthesis process. Metal foams due to their unique properties for industrial applications such as filters, heat exchangers, and catalysts are good insulation. One of the problems is that the production of foams between metal melting point intermetallic compounds is higher than metals, so the production process will be problematic. Among the various methods of extraction, combustion synthesis process due to easy, does not require expensive equipment and production comes to a porous considered appropriate. Intermetallic compounds (MoSi2), one of the most important silicide compounds used in high temperatures, which has a relatively low density, good electrical and thermal conductivity and excellent resistance to oxidation at high temperatures and can be with this the production method. In the present study the combustion synthesis process for the production of MoSi2 is studied. Hence, for the production of metal foam between MoSi2, the silicon and molybdenum powders with stoichiometric ratio mixture prepared by mixing the different pressures, different density and production. Then the samples in the chamber for combustion synthesis process for the synthesis of spontaneous combustion and were explosive combustion synthesis. After combustion synthesis processes on aim to define the fuzzy, chemical composition and structures created, tests of samples by X-ray diffraction (XRD), X-ray energy spectroscopy (EDS), scanning electron microscopy (SEM) and optical microscopy were used. In order to uniform the structure and strength of the final product, synthesized in the plasma sintered () at four different times: 5, 10, 20 and 30 minutes were data. . However, due to low strength Gndlh¬Hay synthesized by the process of the sintered samples were plasma. The results of the also showed that the samples with increased strength during this process, always increases. Also, this process can have a significant impact on the content and structure. Thus combustion synthesis process with process can-be used as a new method of making intermetallic compound MoSi2 to be raised. key words: The metal foam, spontaneous combustion synthesis, detonation synthesis, sintering, porosity.
