Аннотация

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.
