Scrap zinc or concentrated zinc ores are dissolved in sulfuric acid, the solution is purified, and the two solutions are reacted. A heavy mixed precipitate results that is 28 to 30% zinc sulfide and 72 to 70% barium sulfate.

Due to its low binder requirement, lithopone provides paints with good flow and application properties. In the plastic processing industry, it is added to plastics to increase the plastic product’s UV tolerance, thus increasing its outdoor life. In the leather industry, it is one of the sulfide-based white pigments. It is also used in the production of linoleum floorings.
R960 TIO2 , a unique titanium dioxide variant, has emerged as a cornerstone in sectors ranging from advanced manufacturing to renewable energy technologies due to its exceptional properties. This compound boasts enhanced optical and electrical characteristics, making it invaluable for uses such as photocatalysis, sensor development, and even in the production of solar cells. Its impact on technological progress is profound, driving efficiencies that were once deemed unattainable. In conclusion, lithopone pigments, as manufactured by dedicated producers worldwide, are integral to numerous industries. Their production involves a complex yet precise process, and the manufacturers' continuous efforts to enhance product quality and sustainability ensure the ongoing relevance of lithopone pigments in the global market. With the increasing demand for efficient and environmentally friendly materials, the future of lithopone pigments as a key pigment choice appears promising.Although barium sulfate is almost completely inert, zinc sulfide degrades upon exposure to UV light, leading to darkening of the pigment. The severity of this UV reaction is dependent on a combination of two factors; how much zinc sulfide makes up the pigments formulation, and its total accumulated UV exposure. Depending on these factors Lithopone B301, Lithopone B311 powder itself may vary in shade over time, ranging from pure white all the way to grey or even black. To suppress this effect, a dopant might be used, like small amount of cobalt salts, which would be added to the formulation. This process creates cobalt-doped zinc sulfide. The cobalt salts help to stabilize zinc sulfide so it will not have as severe a reaction to UV exposure.
We've used titanium dioxide safely for decades. However, recently its safety was called into question.
At CRIS, we've explored the safety of titanium dioxide for nearly half a decade, including conducting double-blind research to test the safety of food-grade titanium dioxide (E171). Our study shows that when exposed to food-grade titanium dioxide in normal conditions, research animals did not experience adverse health outcomes.
It's important to emphasize that in a National Institutes of Health study, experimental animals were exposed to titanium dioxide in amounts as high as 5% of their diet for a lifetime and showed no evidence of adverse effects.
A handful of studies greatly influenced the decisions made by the European Food Safety Authority (EFSA). Unfortunately, these studies did not consider that titanium dioxide exposure comes from food, not drinking water. Additionally, CRIS researchers could not reproduce the adverse outcomes identified by the studies through typical food ingestion. Regardless, the EFSA banned E171 as a food ingredient and for use in other capacities in the summer of 2022.
In 2022, the United States, United Kingdom, and Canada maintained that the scientific evidence supports that titanium dioxide (E171) is safe for humans to use and consume.
Below 20% substitution, it is recommended to replace 1 kg of TiO2 with 1 kg of Lithopone.
Conclusion In the automotive industry, titanium dioxide coatings are applied to vehicle bodies to resist corrosion and to offer a lustrous finish that stands out on the road2.Inorganic white pigment. Widely used as a white pigment for plastics, paints and inks such as polyolefins, vinyl resins, ABS resins, polystyrene, polycarbonate, nylon and polyoxymethylene.
Lithopone B301, Lithopone B311 powder, brilliant white pigment used in paints, inks, leather, paper, linoleum, and face powder. It was developed in the 1870s as a substitute or supplement for lead carbonate (white lead), to overcome its drawbacks of toxicity, poor weathering, and darkening in atmospheres that contain sulfur compounds. Lithopone B301, Lithopone B311 powder is an insoluble mixture of barium sulfate and zinc sulfide that precipitates upon mixing solutions of barium sulfide and zinc sulfate. The precipitate is recovered by filtration, then calcined (roasted) at temperatures above 600° C (1,112° F). Although Lithopone B301, Lithopone B311 powder has been replaced in many applications by titanium dioxide, it is still widely used in a number of products, such as water paints.

Food-grade titanium dioxide differs from what’s added to plastics and paints to enhance whiteness. However, there have been concerns about the environmental impact of titanium dioxide production and the potential health risks from exposure to its particles.
Several global companies specialize in the production and supply of rutile TiO2. These suppliers invest heavily in research and development to improve the purity and performance of their products. They also offer tailored solutions, catering to the specific needs of their clients. Some well-established suppliers include Cristal Global, Tronox, and Evonik, among others, each known for their commitment to quality and customer satisfaction.
Based on this opinion, the European Commission and the Member States agreed to remove all uses of titanium dioxide as an additive in food. In January 2022, a Regulation withdrawing the authorisation to use titanium dioxide as a food additive in food products was adopted i.e. Commission Regulation (EU) 2022/63.
The use of barium sulfate boards is not limited to conventional radiography; it extends to advanced imaging techniques such as fluoroscopy and computed tomography (CT). During a fluoroscopic procedure, real-time images are captured as the patient swallows or is injected with the barium solution, allowing for the observation of the GI tract's dynamic processes such as peristalsis and the opening of sphincters.Most food-grade titanium dioxide is around 200–300 nanometers (nm) in diameter. This size allows for ideal light scattering, resulting in the best color (1Trusted Source).

The global market for titanium dioxide suppliers is highly competitive, with numerous players vying for a larger share of the pie. Some of the leading suppliers include DuPont, Tronox, Cristal Global, and Huntsman Corporation. These companies have established themselves as reliable sources of titanium dioxide by consistently delivering products that meet or exceed customer expectations. In addition to paints and coatings, titanium oxide is also used in the production of ceramics. It is added to ceramic glazes to give them a smooth, glossy finish and to improve their durability. Titanium oxide is also commonly used in the production of glass, where it helps to provide clarity and strength.
