The properties of lithopone are very suitable for use in the production of coatings. Because the ingredients of lithopone are zinc sulfide and barium sulfate, and the more zinc sulfide content, the stronger its covering power. This indicates a paint product with strong white covering power. It is different from water in that it reacts with acid but does not react with alkali. It has a wide range of uses. Because its structural properties are similar to titanium dioxide and its price is relatively cheap, it can also be used as a substitute for some titanium dioxide. Lithopone can be used for coloring paints, inks, pigments, rubber, paper, leather, enamel, etc.

It turns into light gray after being exposed to ultraviolet rays in sunlight for 6 to 7 hours, but it will return to its original color when placed in a dark place. It is easy to oxidize in the air and then agglomerate and deteriorate when exposed to moisture.

Lithopone is produced by coprecipitation of barium sulfate and zinc sulfide. Most commonly coprecipitation is effected by combining equimolar amounts of zinc sulfate and barium sulfide:

How can I tell if a product has titanium dioxide in it? How can I avoid the ingredient?

Apart from the cosmetics industry, the coatings and plastics industry is also expected to contribute significantly to the growth of titanium dioxide in 2023. Coatings made from titanium dioxide offer excellent hiding power, durability and weather resistance, making them ideal for outdoor applications. Demand for high-quality coatings is expected to surge as the construction and automotive industries expand. Titanium dioxide is at the forefront of providing aesthetic and protective coatings, making it an indispensable ingredient in the industry.

Titanium dioxide prices in the Asian market skyrocketed due to high demand and limited stock availability. Prices in the Chinese market surged significantly, reaching 2875 USD /MT at the end of March, well above the USD 2015/MT level in January 2021.

Another factor to consider is customer service and after-sales support. With suppliers located in different countries, clear communication and reliable support are critical. Manufacturers who provide comprehensive technical support and guidance on their products can help clients navigate challenges that may arise during production.

TiO₂ comes in many different forms. However, only a few of these forms are considered food-grade (acceptable to be added to food). Many studies that raised concern about the safety of TiO₂, including the concern for genotoxicity, used forms of TiO₂ that are not considered acceptable for use in food and have different properties than food-grade TiO₂. Other studies did use food-grade TiO₂, but took steps to break the material down into smaller particles than what would normally be found in food.
