　　Titanium tetrachloride is mainly used for the production of sponge titanium, titanium dioxide, and titanium trichloride. There are many methods for its production, mainly including boiling chlorination, molten salt chlorination, and vertical furnace chlorination. Boiling chlorination is currently the main method for producing titanium tetrachloride (used in China, Japan, and the United States), followed by molten salt chlorination (used in CIS countries), while vertical furnace chlorination has been phased out. Boiling chlorination generally uses high-grade titanium rich materials with low calcium and magnesium content as raw materials, while molten salt chlorination can use raw materials with high calcium and magnesium content.

　　1. Boiling chlorination

　　Boiling chlorination is a method of producing titanium tetrachloride by reacting fine grained titanium rich materials with solid carbonaceous (petroleum coke) reducing agents in a fluidized state under the action of high temperature and chlorine gas flow. This method has the characteristics of accelerating mass and heat transfer between gas and solid phases, and enhancing production. The raw materials used for boiling chlorination both domestically and internationally include high titanium slag, natural rutile, and artificial rutile. The diameters of the newly built boiling chlorination furnaces at Fushun Titanium Plant and Zunyi Titanium Plant in China are Φ 1.4 m and Φ 2.4 meters, using * * * sieve plate chlorination technology, with Zunyi Titanium Factory designed to produce 70 tons of crude titanium tetrachloride per day.

　　2. Molten salt chlorination

　　Molten salt chlorination is a method of preparing titanium tetrachloride by suspending finely ground titanium slag, rutile, and petroleum coke in a molten salt (mainly composed of KCl, NaCl, MgCl2, and CaCl2) medium and introducing chlorine gas. Generally, waste electrolytes from electrolytic magnesium can also be used, and chlorine gas can be injected under the conditions of 973K~1073K. Therefore, the speed of chlorination reaction is influenced by factors such as the properties and composition of the melt, the type of reducing agent, the properties of the raw materials, chlorination temperature, chlorine gas concentration and injection rate, melt height, and carbon dosage.
