Development Status of Titanium Dioxide Industry

1. Overview

Titanium dioxide is a white inorganic pigment with good covering properties, stability, gloss and weather resistance. The titanium dioxide industry mainly has two production methods: sulfuric acid method and chlorination method. The chlorination method uses artificial rutile, high titanium slag (chlorination slag) or natural rutile as raw materials, and produces titanium tetrachloride through chlorination, and then undergoes distillation and purification, gas phase oxidation, rapid cooling, and gas-solid separation to obtain titanium dioxide. The sulfuric acid method uses titanium concentrate or acid-soluble titanium slag as raw materials, uses sulfuric acid to decompose the titanium concentrate or titanium slag, and obtains titanium dioxide through filtration, hydrolysis, calcination, pulverization and other processes.

2. Development environment

As an important inorganic chemical product, titanium dioxide is widely used in coatings, plastics, papermaking, ink, chemical fiber, rubber and other fields. Its end products are used in rapidly developing industries such as real estate, automobile industry, and decorative paper. In recent years, with the With the development of science and technology, the consumption of titanium dioxide has expanded to new energy, high-end equipment, environmental protection, medical and other fields, and its application prospects are very broad.

3. Development status

Titanium dioxide is considered to be the white pigment with the best performance, widest application and largest consumption. It is widely used in coatings, plastics, papermaking, printing ink, chemical fiber, rubber, cosmetics, enamel, ceramics, electronics, metallurgy, etc., in addition to In addition, it is also widely used in chemical fiber, rubber, food, chemical industry, medicine, ink and other fields.

China is not only a major producer and consumer of titanium dioxide, but also a major exporter. In the first half of 2023, China's titanium dioxide export volume has completed 836,200 tons, and the export value has completed 1,836,125,800 US dollars. The average export price is 2,200 US dollars/ton, and the import quantity It was 32,200 tons, the import amount was US$115.8541 million, and the average import price was US$3,600/ton.
