Titanium dioxide is produced in two main forms. The primary form, comprising over 98 percent of total production, is pigment grade titanium dioxide. The pigmentary form makes use of titanium dioxide’s excellent light-scattering properties in applications that require white opacity and brightness. The other form in which titanium dioxide is produced is as an ultrafine (nanomaterial) product. This form is selected when different properties, such as transparency and maximum ultraviolet light absorption, are required, such as in cosmetic sunscreens.
When examining a lithopone pigment pricelist, one might notice that prices can vary significantly between different grades of lithopone. Generally, there are two main types Lithopone 28 and Lithopone 60, with the numbers denoting the percentage of zinc sulfide content. Lithopone 28, with a lower zinc sulfide content, is often more affordable compared to Lithopone 60, which offers superior whiteness and opacity. The choice between these grades depends largely on the specific requirements of the end application.
Ref. 5% TiO2 - 2. Particle Size and Shape The particle size and shape of ZnS can significantly impact its performance in various applications. Therefore, it is essential to choose suppliers who can offer a range of particle sizes and shapes to suit different requirements.
- Titanium dioxide, commonly known as TiO2, is a widely used inorganic compound that exists in several crystalline forms including anatase, rutile, and brookite. Among these, anatase titanium dioxide (TiO2) with its specific surface area codenamed B101 has garnered significant attention due to its unique properties and applications in various industries. In this article, we delve into the world of titanium dioxide anatase B101 suppliers, exploring their role and the benefits they offer to consumers.

- What are the transportation requirements for setting up a lithopone manufacturing plant?
- The versatility of rutile type TiO2 extends to the field of cosmetics, where its non-toxic nature and ability to reflect UV light make it an ideal sunscreen ingredient. It is also utilized in food coloring due to its safety and efficacy in providing bright, appealing hues to food products.
Having thus described the origin and uses of the pigment, we now come to the question, what is lithopone? It is, in short, a chemical compound usually consisting of 30.5 per cent zinc sulphide, 1.5 per cent zinc oxide and 68 per cent barium sulphate, but these proportions vary slightly in the different makes. Lithopone of this composition is sold as the highest grade, either as red seal or green seal, as it best suits the idea of the manufacturer. Many manufacturers, especially in Europe, sell and also export other brands under other seals, containing 24, 20, 18 and as little as 12 per cent of zinc sulphide with very small percentages of zinc oxide, the balance being usually barium sulphate, but sometimes certain portions of China clay or gypsum (calcium sulphate) or whiting (calcium carbonate). Such brands are not a chemical compound, but mechanical mixtures of the chemically compounded lithopone and the admixtures referred to.

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.
Titanium dioxide (E171) is an additive that is used in food as a colour. The function of food colours is to make food more visually appealing, to give colour to food that would otherwise be colourless, or to restore the original appearance of food. Titanium dioxide is used to provide whiteness and opacity to foods.
Moreover, titanium dioxide is also used in rubber formulations to improve the processing and curing properties of rubber compounds. It acts as a catalyst in the vulcanization process, speeding up the cross-linking of rubber molecules and enhancing the overall performance of the final product. This results in rubber products that are stronger, more flexible, and better suited for a wide range of applications.
Lithopone 30% is the perfect solution for partial substitution of TiO2 in fillers due to its very soft nature and hardly any shrinkage properties.
