Abstract:
1. A vapor phase process for producing a titanium oxide comprising: preliminarily heating each of a titanium halogenide-containing gas and an oxidative gas at a temperature of at least 600° C. but less than 1,100° C. before introducing the titanium halogenide-containing gas and the oxidative gas into a reactor reacting the titanium halogenide-containing gas with the oxidative gas by introducing the titanium halogenide-containing gas and the oxidative gas into the reactor, to thereby allow reaction to proceed, with the temperature of the interior of the reactor being 900° C. to less than 1,000° C., and maintaining a residence time of the titanium halogenide-containing gas and the oxidative gas in the reactor at temperature range of 900° C. to less than 1,000° C. of 0.005 seconds to 0.05 seconds to obtain a low rutile titanium oxide having a rutile content of 5% or less.
