Barium sulfide is produced by carbothermic reduction of barium sulfate. Zinc sulfate is obtained from a variety of zinc products, often waste, by treatment with sulfuric acid.
- As consumer demand for products with titanium dioxide continues to grow, manufacturers must continue to adapt and innovate to stay competitive in the market. By focusing on quality, safety, and sustainability, manufacturers of products with titanium dioxide will continue to play a key role in the industry for years to come.
- BaS + ZnSO4→ ZnS · BaSO4
- It is crucial for consumers and manufacturers alike to choose suppliers who adhere to stringent quality control measures and follow responsible sourcing practices. The selection of food-grade anatase titanium dioxide not only impacts the visual appeal and shelf life of food products but also influences consumer trust and safety.
Key benefits for stakeholders
Lithopone is an inorganic white pigment, obtained from co-precipitation of Zinc sulfide (ZnS) and Barium sulfate (BaSO4). As a white pigment, it acts as a cost-effective alternative for TiO2. Some of the properties of Lithopone include high brightness and performance under UV exposure. Lithopone requires less wetting agent to achieve optimum wetting of its surface. It is commercially graded on the basis of amount of ZnS. Its grades include 28%, 30%, and 60% ZnS. As a comparatively inexpensive white pigment, Lithopone is presently used in various paint formulations, road marking paints, jointing compounds, and putties.

Lithopone 30% is a perfect alternative to titanium dioxide in all natural and synthetic pigmented elastomers, as it is non-abrasive and extremely acid resistant.
Lithopone(CAS NO.1345-05-7) is manufactured by a process in which barium sulfide solution is prepared by reducing barite ore (BaSO4) with carbon and leaching the resulting mass.
3.Used for coloring rubber products, varnishes, leather, paper, enamel, etc.
This article discusses the discovery of phosphorescent lithopone on watercolor drawings by American artist John La Farge dated between 1890 and 1905 and the history of lithopone in the pigment industry in the late 19th and early 20th centuries. Despite having many desirable qualities for use in white watercolor or oil paints, the development of lithopone as an artists’ pigment was hampered by its tendency to darken in sunlight. Its availability to, and adoption by, artists remain unclear, as colormen's trade catalogs were generally not explicit in describing white pigments as containing lithopone. Further, lithopone may be mistaken for lead white during visual examination and its short-lived phosphorescence can be easily missed by the uninformed observer. Phosphorescent lithopone has been documented on only one other work-to-date: a watercolor by Van Gogh. In addition to the history of lithopone's manufacture, the article details the mechanism for its phosphorescence and its identification aided by Raman spectroscopy and spectrofluorimetry.
