Le lithopone a été découvert dans les années 1870 par DuPont. Il a été produit par la Krebs Pigments and Chemical Company, entre autres1. Il se faisait en différents grades, en fonction de la teneur en sulfure de zinc. Les qualités « bronze » et « or » contenaient 40 à 50 % de sulfure de zinc, ce qui les rendaient particulièrement couvrantes2. Bien que ce pigment ait atteint son pic de popularité autour de 1920, il s'en produisait encore annuellement plus de 220 000 tonnes en 1990. Il est principalement utilisé dans les peintures, les pâtes et les plastiques3.

Its capacity to enhance durability, color, and sustainability resonates with contemporary demands for high-performance and eco-friendly materials. As China continues to make strides in industrial innovation, the story of TIO2 remains a compelling chapter in the narrative of progress and preservation. Furthermore, wholesale titanium dioxide 298 is known for its exceptional stability and durability. It is resistant to UV rays, chemicals, and weather conditions, making it a reliable choice for outdoor applications. This durability ensures that products maintain their color and appearance over time, saving manufacturers and consumers from frequent maintenance and replacement costs.
Titanium dioxide comes in the form of a white powder and is sometimes used in cosmetics to adjust a color to a lighter shade. This is also why it can produce a white cast.
A 2022 review on past studies of titanium dioxide and rat lung cancer, for instance, said the original study was under extreme conditions and its effects were not replicated in other animal species. Additionally, the review concluded that the few studies which did directly focus on titanium dioxide's impact on humans did not end up showing any increased cancer risk.
Titanium dioxide is used in an enormous range of food products, which can feel jarring when looking at some of its other uses.
A dense, white, opaque pigment composed of a mixture of Zinc sulfide (30%) and Barium sulfate (70%) with trace amounts of Zinc oxide. Lithopone, first produced in 1874, was called Orr's white. The mixture of the two components is so intimate that it is hard to distinguish microscopically. Lithopone is an inert, transparent pigment which is often used as a filler or as a base for lake pigments. Lithopone was widely used in house paints in the first half of the 20th century. It was also used for some artist grounds, inks and as a filler in Paper, Leather, and Linoleum. Now lithopone has mostly been replaced by Titanium dioxide.

When manufacturers add titanium dioxide to foods and other ingestible products, it’s typically referred to as E171, which relates to food-grade purity.
Another classification lies in the scale of operation. Large-scale calcium carbonate factories, often equipped with advanced machinery and automation, cater to the demands of the global market. In contrast, small-scale or local factories, while having a lower production capacity, might serve regional needs or specialize in niche products. In summary, our factory represents a benchmark in the manufacture of TIO2 powder rutile titanium dioxide. By adhering to exacting standards of quality, embracing technological innovation, and dedicating ourselves to sustainability, we produce a TiO2 powder that stands out for its superior performance and reliability—a testament to our dedication to excellence in manufacturing.The biological activity, biocompatibility, and corrosion resistance of implants depend primarily on titanium dioxide (TiO2) film on biomedical titanium alloy (Ti6Al4V). This research is aimed at getting an ideal temperature range for forming a dense titanium dioxide (TiO2) film during titanium alloy cutting. This article is based on Gibbs free energy, entropy changes, and oxygen partial pressure equations to perform thermodynamic calculations on the oxidation reaction of titanium alloys, studies the oxidation reaction history of titanium alloys, and analyzes the formation conditions of titanium dioxide. The heat oxidation experiment was carried out. The chemical composition was analyzed with an energy dispersive spectrometer (EDS). The results revealed that titanium dioxide (TiO2) is the main reaction product on the surface below 900°C. Excellent porous oxidation films can be obtained between 670°C and 750°C, which is helpful to improve the bioactivity and osseointegration of implants.
