The Formula and Suppliers of Lithopone A Comprehensive Overview

Lithopone, a white pigment that combines zinc sulfide and barium sulfate, has been utilized widely in various applications such as paints, coatings, plastics, and even in the cosmetics industry. With growing demand for high-quality pigments in these sectors, understanding the formula and sourcing options for lithopone is essential for manufacturers and suppliers alike.

The chemical formula for lithopone can be represented as ZnS·BaSO4, indicating that it is essentially a composite of zinc sulfide (ZnS) and barium sulfate (BaSO4). This combination results in a pigment that offers excellent opacity, brightness, and durability, making it a preferred choice over traditional white pigments like titanium dioxide in some applications. Lithopone not only provides color but also enhances the durability of the material, making it an attractive option for manufacturers seeking long-lasting results in their products.

The production of lithopone involves several steps, starting with the reaction of zinc oxide and barium sulfide in an aqueous solution. This process yields a precipitate of lithopone, which is then filtered, washed, and dried before being finely ground into a powder suitable for various applications. The quality of lithopone can vary, depending on the purity of the source materials and the production process, making it vital to source from reputable suppliers.

When it comes to sourcing lithopone, several suppliers excel in providing high-quality products. Companies specializing in chemical manufacturing and pigment production often offer lithopone as part of their product lines. A few well-known suppliers include

1. Kronos Worldwide Renowned for its high-quality titanium dioxide pigments, Kronos also produces lithopone, maintaining strict quality control to ensure consistency and performance.

2. BASF As a leading chemical company, BASF provides a range of pigments, including lithopone. Their extensive research and production capabilities enable them to offer tailored solutions for diverse applications.

3. Huntsman Corporation With a strong focus on innovation and sustainability, Huntsman produces fine chemical products, including lithopone, catering to the needs of various industries.
