Understanding Lithopone Suppliers and Market Insights

Lithopone is a widely used pigment known for its excellent opacity, brightness, and chemical stability. It is a significant component in various applications, including coatings, plastics, rubber, and inks. Specifically, lithopone is a complex mixture of barium sulfate (BaSO4) and zinc sulfide (ZnS), which contributes to its desirable properties. The typical content of lithopone in products usually ranges between 28% to 30%. This article explores the characteristics of lithopone, its applications, and key suppliers in the market.

What is Lithopone?

Lithopone is primarily recognized for its ability to provide opacity and whiteness, making it a popular choice in the production of white pigments. It is often utilized as a substitute for titanium dioxide due to its cost-effectiveness and low toxicity, although it does not quite match titanium dioxide's performance in terms of opacity and brightness. Lithopone's formulation generally contains 28% to 30% zinc sulfide, which enhances its performance in diverse applications.

The manufacturing process of lithopone typically involves the precipitation of zinc sulfide from zinc sulfate solution in the presence of barium sulfate. This process not only ensures a high-quality product but also allows for the control of particle size and distribution, which influences its performance characteristics. Suppliers of lithopone must adhere to strict quality standards to ensure that their products meet the specific requirements of different industries.

Applications of Lithopone

Lithopone finds extensive use across various industries due to its favorable properties
