Iron Carbide exist in earth's lower mantle and it crystallize in various crystallographic structure depending upon the thermodynamic conditions. The thermodynamic state of lower earth region are quite complicated due to simultaneous effect of pressure and/or temperature. In such a situation the study of pressure dependent properties of FeC is important. In the present paper, we report the structural properties of FeC using first principles calculations. The structural properties are studied at various pressures in order to determine the high pressure behavior of this carbide in rock salt structure. The computed properties agree well with the previously reported results. One of the most important properties of the material is the pressure induced structural phase transition from one phase to another. In the present study, we do not observe any structural phase transition from rock salt structured FeC to CsCl structured FeC up to 100 GPa. The present results are also useful as FeC is refractory carbide, a material of great technological importance at non ambient conditions.Keywords
