Titanium dioxide, also known as TiO2, is a white pigment that is highly stable and non-toxic. It is commonly used in paints, plastics, papers, and cosmetics due to its excellent brightness and high refractive index. In the paint industry, titanium dioxide is added to enhance the opacity and durability of the product, ensuring long-lasting protection for surfaces. Manufacturers rely on this pigment to produce high-quality paints that meet customer demands for superior performance and aesthetic appeal.

Procurement of TIO2 involves a complex process, starting from sourcing the raw materials, primarily ilmenite, rutile, or titanium-bearing slag, to negotiating contracts with suppliers. Manufacturers often prioritize suppliers that can guarantee consistent quality, competitive pricing, and reliable delivery schedules. This necessitates strong relationships and strategic partnerships with mining companies, which are typically located in regions rich in titanium resources, such as Australia, South Africa, and Canada.

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.
