Despite being produced in China, both calcium carbonate and titanium dioxide are also important import commodities for the country. China imports calcium carbonate from countries like Vietnam, Indonesia, and Malaysia, while it imports titanium dioxide from countries like Germany, Japan, and the United States.

The raw material used in this method is FeSO4. In order to maintain the Fe3 + concentration in the reaction medium in a specific range, reducing agent iron sheet is added in the reaction process. Iron yellow crystal seed was added and air was introduced to synthesize iron yellow under certain pH conditions. The method mainly includes two steps: (1) firstly, FeSO4 · 7H2O is used as raw material, NaOH or NH3 · H2O is used as precipitant or pH regulator, and air is used as oxidant to prepare crystal seed; (2) Iron yellow is produced by two-step oxidation with crystal seed, FeSO4, iron sheet and air.

The production of titanium dioxide in China is mainly concentrated in the eastern provinces of Shandong, Jiangsu, and Henan. These provinces are home to numerous titanium dioxide manufacturers, both large and small, that cater to the domestic and international markets. The industry has been growing rapidly in recent years due to the increasing demand for titanium dioxide worldwide.
