Tioxide process. This process is similar to that used to produce fumed silicas. Ultra-low particle size titanium dioxide (15-35 nm) is obtained for use as photocatalyst or UV absorber (for instance in sun protective creams).

Lithopone B301, Lithopone B311 powder is widely used in coatings, printing ink, rubber, plastic industry, etc.

In recent years, titanium dioxide (TiO2) has gained immense popularity across various industries due to its excellent properties, such as high opacity, brightness, and ultraviolet light absorption. As a result, the demand for titanium dioxide has increased significantly, prompting a surge in the number of manufacturers hoping to capitalize on this booming market. While quality remains a priority, cost-effectiveness has emerged as a crucial factor for consumers, leading to a growing interest in cheap titanium dioxide manufacturers.

Lithopone factory : What should we pay attention to when purchasing?

Lithopone was discovered in the 1870s by DuPont. It was manufactured by Krebs Pigments and Chemical Company and other companies. The material came in different seals, which varied in the content of zinc sulfide. Gold seal and Bronze seals contain 40-50% zinc sulfide, offering more hiding power and strength. Although its popularity peaked around 1920, approximately 223,352 tons were produced in 1990. It is mainly used in paints, putty, and in plastics.

TiO₂ absorbs UV light. This property makes it appear bright white under light, unlike other white materials that can look slightly yellow.

Topical Exposure 

Scientists analyzed research that examined how titanium dioxide nanoparticles interact with the brain for a 2015 review published in Nanoscale Research Letters. The researchers wrote: “Once the TiO2 NPs are translocated into the central nervous system through [certain] pathways, they may accumulate in the brain regions. For their slow elimination rates, those NPs could remain in the brain zones for a long period, and the Ti contents would gradually increase with repeated exposure.” After reviewing dozens of studies, the scientists concluded: “Long-term or chronic exposure to TiO2 nanoparticles could potentially lead to the gradually increased Ti contents in the brain, which may eventually induce impairments on the neurons and glial cells and lead to CNS dysfunction as a consequence.”
