Process Description
Titanium dioxide, also known as TiO2, has a CAS number of 13463-67-7. It is a soft, odorless and tasteless white powder with strong hiding power and tinting strength, with a melting point of 1560–1580°C. It is insoluble in water, dilute inorganic acids, organic solvents, and oils; slightly soluble in alkalis; and soluble in concentrated sulfuric acid. It turns yellow when heated and reverts to white upon cooling. As an inert pigment, it is considered the best-performing white pigment available in the world. Rutile titanium dioxide is dominant in China, accounting for approximately 86.5% of total production in 2023.

Technology comment
The production of rutile titanium dioxide currently involves the coexistence of the "sulfuric acid method" and the "chlorination method". Among them, the sulfuric acid method occupies an absolutely dominant position in production capacity, and the chlorination method represents the future technological development direction. In 2023, in the classification of titanium dioxide production methods in China, sulfuric acid titanium dioxide was still the main production method, with an annual output of approximately 3.468 million tons, accounting for 83.37%, while China's comprehensive output of chloride titanium dioxide accounted for 16.63%.
