Titanium dioxide (TiO2). Titanium dioxide is the most common white pigment used today. As a pigment, titanium dioxide is unique because it combines both high colouring and high opacifying capacity. This is mainly due to its high refractive index (2.7). Furthermore, titanium dioxide is an excellent UV absorber (it is used in sun protective creams). Some typical properties are: density 3.3-4.25 g/cm3; pH of water suspension 3.5-10.5; particle size 8–300 nm; oil absorption 10–45 g/100 g; specific surface area 7–160 m2/g. Most titanium dioxide is produced from the rutile (TiO2) or ilmenite (titanate of ferrous iron). Titanium dioxide can be obtained using different processes.

The production of lithopone is associated with several environmental concerns, including air and water pollution. Zinc sulfide ore mining can lead to soil erosion and habitat destruction, while sulfuric acid leaching and calcination processes can release pollutants into the air and water. To address these issues, many Chinese lithopone factories have implemented environmental protection measures such as wastewater treatment and emission reduction technologies.
