1. The production of titanium dioxide in the world is mainly based on the chlorination method

In addition to China, the global titanium dioxide production capacity is very high. The top five suppliers have mastered 52% of the world's total capacity, or 3 million 870 thousand tons. As the leader of titanium dioxide industry, these overseas giants dominate the supply, price and development of titanium dioxide to a large extent.

Chemours, 1 million 242 thousand tons, 100% chlorination;

Venator (separated from Huntsman), 810 thousand tons, 100% chlorination;

Cristal, 858 thousand tons, 87% chlorination;

Connos Kronos, 559 thousand tons, 79% chlorination method;

Tronox, 465 thousand tons, 62% chlorination;

In the five large multinational titanium dioxide producers, about 85% of the production capacity adopts the chlorination process, and the contrast is that only 6% of the products produced by the local titanium dioxide producers are used in the chlorination process.

2. The production of titanium dioxide in China's chlorination method is only 5.83%

According to the statistics of the Secretariat of the National Chemical Industry Productivity Promotion Center titanium white center and titanium white powder industrial technology innovation alliance, in 2017, the comprehensive production of 41 full flow titanium dioxide enterprises (Group), which can maintain normal production, was 2 million 869 thousand and 500 tons, of which the rutile type was 2 million 276 thousand and 400 tons, the anatase type was 443 thousand and 300 tons, and the non pigments were non pigments. The class is 149 thousand and 800 tons.

The total output reached 100 thousand tons or more of the total number of enterprises in 10.

The total output of the above 10 enterprises with a real output of 100 thousand tons or more is 1 million 860 thousand tons, accounting for 64.82% of the total output of the country. The comprehensive production of titanium dioxide in 4 sections of Sichuan Deyang, Hubei Xiangyang and Henan Jiaozuo, Deyang, Hubei, Xiangyang and Henan Jiaozuo, accounted for 20.19% of the total output of the country, leading to the industry.

The production of titanium white powder by chlorination method in 2017 accounted for 5.83% of the total production of titanium white powder. The total output of 5 chlorination titanium dioxide production enterprises (Dragon Python Bailey, Jinzhou titanium industry, Yunnan Xinli, Luohe Xingmao and Panzhihua Steel Vanadium and titanium) was 167 thousand and 500 tons, an increase of 62 thousand and 100 tons and 58.96% more than that of the previous year.

At present, the homogeneity of titanium dioxide still exists in China. Besides the difficult technology to break the chlorination process titanium white powder, it is also a good way to develop the special titanium white powder. Production enterprises should develop different types of titanium dioxide according to the different application fields of downstream users. For example, plastic special, chemical fiber grade, food grade, electronic grade, nanometer level, denitration titanium dioxide and so on.
