Chlorination of titanium oxycarbonitride produced by carbothermal nitridation of rutile / Andrew Adipuri in Industrial & engineering chemistry research, Vol. 48 N°2 (Janvier 2009) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 48 N°2 (Janvier 2009) . - p. 779–787 Titre : Chlorination of titanium oxycarbonitride produced by carbothermal nitridation of rutile Type de document : texte imprimé Auteurs : Andrew Adipuri, Auteur ; Guangqing Zhang, Auteur ; Oleg Ostrovski, Auteur Année de publication : 2009 Article en page(s) : p. 779–787 Note générale : chemical engineering Langues : Anglais (eng) Mots-clés : Titanium  oxycarbonitride Résumé : Titanium oxycarbonitride was produced by carbothermal nitridation of rutile. Mixtures consisting of titania and graphite with different carbon to titanium dioxide molar ratios were pressed into pellets and subsequently heated under nitrogen atmosphere at 1450 °C. Titanium oxycarbonitride was chlorinated in a horizontal tube furnace using chlorine and Cl2−N2 gas mixture. 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 150−200 °C. Chlorine partial pressure in Cl2−N2 gas mixture, gas flow rate, and particle size affected the chlorination rate, while the effect of particle size was insignificant. Extent of chlorination of titanium oxycarbonitride produced with carbon-to-titania molar ratio at 2.5 was close to 100% after 40 min of reaction.
