Реферат: eng: The results of experimental synthesis of carbide Fe7C3 at 5.5 GPa are presented. It is found that carbide Fe3C and several polytypes of carbide Fe7C3 are formed along with diamond during cooling of the system. It is considered that the Fe7C3 phase is a component of the Earth's inner core. Our results indicate that polytypic carbide modifications could have been formed under natural conditions at relatively low pressures during differentiation of the Earth.
