Chlorination of titanium oxycarbide produced by carbothermal reduction of rutile

Journal Article


Abstract


  • Titanium oxycarbide was produced by carbothermal reduction of rutile. Mixtures of titania and graphite with different carbon to titania molar ratio were pressed into pellets and heated under argon atmosphere at 1450 °C. Titanium oxycarbide was chlorinated in a horizontal tube furnace. Effects of furnace temperature, chlorine partial pressure, gas flow rate, and particle size on the rate and extent of chlorination were examined. The chlorination was ignited at 150 °C to 200 °C. Chlorine partial pressure and gas flow rate strongly affected the chlorination rate, while the effect of particle size was insignificant. Best chlorination results were obtained for titanium oxycarbide produced with carbon to titania molar ratio 2.5, and chlorination was close to 100 pct in 30 minutes. © 2008 The Minerals, Metals & Materials Society and ASM International.
