Fluorine Chemical, Lithopone 30% CAS No. 1345-05-7, white powder, relative density: 4.136 ~ 4.39 g / mL, insoluble in water. It is a mixture of zinc sulfide and barium sulfate. Inorganic white pigment, widely used in plastics such as polyolefin, vinyl resin, ABS resin, polystyrene, polycarbonate, nylon and polyoxymethylene, and white pigments of paints and inks. It is less effective in polyurethane and amino resins and less suitable in fluoroplastics. It is also used for coloring of rubber products, paper, varnish, tarpaulin, leather, watercolor paint, paper, enamel, and the like. Used as a binder in the production of electric beads.

Résumé–Cet article traite de la découverte de lithopone phosphorescent sur des dessins à l'aquarelle, datés entre 1890 et 1905, de l'artiste Américain John La Farge et de l'histoire du lithopone dans l'industrie des pigments à la fin du 19e et au début du 20e siècle. Malgré de nombreuses qualités souhaitables pour une utilisation en tant que blanc dans les aquarelles et les peintures à l'huile, le développement du lithopone comme pigment pour artistes a été compliqué de par sa tendance à noircir lorsqu'il est exposé au soleil. Sa disponibilité et son usage par les artistes demeurent incertains parce que les catalogues des marchands de couleurs n'étaient généralement pas explicites à indiquer si les pigments blancs contenaient du lithopone. De plus, lors d'un examen visuel, le lithopone peut être confondu avec le blanc de plomb et sa phosphorescence de courte durée peut facilement être ignorée par l'observateur non averti. À ce jour, le lithopone phosphorescent a seulement été documenté sur une autre œuvre: une aquarelle de Van Gogh. En plus de l'histoire de la fabrication du lithopone, cet article décrit le mécanisme de sa phosphorescence et son identification à l'aide de la spectroscopie Raman et de la spectrofluorimétrie.

Manufacturers of rutile titanium dioxide employ different processes to produce this versatile pigment. The two primary methods are the sulfate process and the chloride process. In the sulfate process, ilmenite ore is treated with sulfuric acid to form titanyl sulfate solution, which is subsequently processed into titanium dioxide. This method typically results in a more opaque and durable pigment that is preferred in applications where weatherability is crucial. On the other hand, the chloride process involves treating rutile ore with chlorine gas to produce titanium tetrachloride, which is then refined and oxidized to form titanium dioxide. This method often yields a higher purity product suitable for applications requiring greater brightness and color stability.
