tio2 industry manufacturers

In recent years, China's production of talc and titanium dioxide has increased significantly, making it one of the world's largest producers of these minerals. According to the US Geological Survey, China produced approximately 2.5 million metric tons of talc and 2.4 million metric tons of titanium dioxide in 2019 alone. This growth can be attributed to the country's vast reserves of these minerals, as well as government initiatives aimed at boosting domestic production and reducing reliance on imports.

In conclusion, while both lithopone and titanium dioxide have their advantages and disadvantages, TiO2 appears to be the better choice for most applications. Its superior whiteness, UV protection properties, and chemical stability make it a popular choice in the paint, plastics, and paper industries. However, for applications where cost and safety are primary concerns, lithopone may still be a viable option. Ultimately, the choice between these two pigments will depend on the specific requirements of the application and the desired balance of performance and cost.

It should also be considered that due to the low pH in the stomach, the increased dissolution of the TiO2 particles may increase its bioavailability and may facilitate the entry of titanium ions into the blood circulation. Despite the relatively large consumption of TiO2 as a food additive, no studies on the effect of pH on its absorption and bioavailability have been found in the literature. This can be attributed to a general belief that TiO2is completely insoluble. However, this is not completely true, as TiO2 particles show a certain degree of solubility.
