Abstract

Abstract

The sources of impurity Al in titanium sponge produced by the Kroll process were analyzed. The impurity Al is mainly derived from titanium tetrachloride and magnesium. Based on the source analysis of Al in titanium tetrachloride, water vapor was introduced for Al removal from titanium tetrachloride during the chlorination process, where 84.22% of Al removal ratio can be obtained at 10 kg/h of water dosage. At the same time, Al in magnesium was removed by adding refining agent, and a favorable effect can be obtained at 20 kg/t of refining agent amount. Influenced by the reaction process for titanium sponge formation, Al is not evenly distributed in titanium sponge. Therefore, it is necessary to carry out Al removal measures from the source materials to produce high-quality titanium sponge.
