Experimental investigation of thermophysical properties of eutectic Mo–C, graphite and tantalum at high temperatures

Abstract

Abstract An experimental technique based on fast electrical heating for investigation of thermophysical properties of refractory materials under high pressures and at high temperatures is considered. A set of thermophysical properties of refractory materials such as specific enthalpy, specific heat capacity, specific resistivity, melting heat of eutectic Mo-C and thermal expansion of graphite and tantalum were determined. The obtained temperature of eutectic melting of MoC0.82 shows close agreement with equilibrium Mo-C phase diagram.
