Abstract
The kinetics of carbothermic reduction of molybdenum oxide with homoge neously mixed carbon black was studied under non-isothermal heating co nditions using a thermobalance. The evolved gases (CO and CO2) were an alysed by a gas chromatograph. A mechanism is proposed to explain the stepwise conversion of oxide to carbide. A model representing stepwise conversion of the above reduction has been developed and the probable rate controlling steps, for different reactions, have been identified .
