Samples of an MoO 3 /phenanthroline complex and an MoO 3 /carbon black mixture were heated below 1400°C in nitrogen to characterize the carbothermal reduction process of the complex. The conversion of crystalline phases by carbothermal reduction followed substantially the same process in both samples but occurred at a temperature 100° to 150°C lower in the complex than in the carbon black mixture. Two possible explanations for this difference are theorized: (1) The complex may provide more intimate contact between the MoO 3 and the intercalated reducing material. (2) The intercalated reducing agents may have a higher reactivity than does the carbon black.
