Abstract

The MoC phase with the WC structure was prepared by a novel synthetic route that involved the stoichiometric disproportionation of a high-temperature phase, Mo3C2, to MoC and M02C at 1000 °C. MoC was found to be thermodynamically stable at temperatures below 1080 °C. From consideration of equilibrium and calorimetric data, the thermodynamic properties of MoC can be established as S2980/R = 4.41(0.3) andΔH2980/R = -3430(800)K,
