The effects of MoO3 addition on the carbothermal reduction of fine TiO2 were studied for obtaining nanopowders and for understanding the mechanism of the carbothermal reduction. TiO2 was mixed with C powder and MoO3 powder. The mixed powder was heat treated in a rotary tube furnace up to 1773 K. The results indicated that the particle size of TiO2 – MoO3 – C powder heated in the rotary tube furnace was comparable to that heated in batch-type furnace. The CO gas concentration during the carbothermal reduction of TiO2 – MoO3 – C powder was measured. It was confirmed that the reduction temperature of titanium oxide decreased with an addition of MoO3.
