An intercalation compound of WOP 2 O 7 /phenanthroline and a mixture of WOP 2 O 7 /carbon black were prepared to have equal carbon contents. Both samples were heated below 1400°C under a nitrogen atmosphere and their thermal degradation behaviors compared, with the following results: (1) CO gas evolved through carbothermal reduction at a temperature 150°C lower in the intercalation compound than in the WOP 2 O 7 /carbon black mixture. (2) Both WP and W formed at temperatures approximately 100°C lower in the intercalation compound than in the mixture. (3) Thermal degradation occurred homogeneously throughout the intercalation compound particles, and the particle morphology remained favorable after thermal degradation.
