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.

- As suppliers of titanium dioxide, we recognize the significance of maintaining consistent quality and supplying our customers with products that meet their specific requirements
- Titanium dioxide's journey into the food industry began with its classification as Generally Recognized As Safe (GRAS) by the US Food and Drug Administration (FDA). This status is granted after rigorous scientific evaluation, ensuring that the substance does not pose any significant health risks when used as intended. In Europe, the European Food Safety Authority (EFSA) also approves its use, but with specific guidelines on maximum levels.
- One of the key products offered by internal wall coating suppliers is damp-proof coatings. Damp can be a serious issue in buildings, leading to a range of problems such as mold growth and structural damage. Damp-proof coatings provide a barrier against moisture, preventing it from seeping into the walls and causing damage. These coatings are essential for maintaining the integrity of the building and ensuring the health and safety of its occupants.

- In the nitrile glove factory setting, the careful dispersion of titanium dioxide particles is crucial. Advanced manufacturing techniques ensure that TiO2 is evenly distributed throughout the nitrile compound, maximizing its benefits without compromising the gloves' thinness or dexterity.
- In addition to paints and coatings, titanium oxide is also used in the production of ceramics. It is added to ceramic glazes to give them a smooth, glossy finish and to improve their durability. Titanium oxide is also commonly used in the production of glass, where it helps to provide clarity and strength.
- Suppliers of titanium dioxide must also consider competition within the industry when setting their prices
- Lithopone 28-30%, also known as B301 and B311, is a white pigment that has been widely used in various industries due to its excellent properties such as high brightness, good weather resistance, and chemical stability. This pigment is primarily composed of zinc sulfide (ZnS) and barium sulfate (BaSO4), which are combined in a specific ratio to achieve the desired color and performance.
Titanium dioxide is predominantly used as a pigment in products such as paints, coatings, plastics, food, cosmetics, and paper. The ability of TiO2 to scatter light and provide a white color makes it an essential ingredient in achieving high-quality finishes in these applications. However, the production of titanium dioxide can be complex and costly, given that it involves raw materials such as ilmenite and rutile, as well as advanced processing technologies. Manufacturers are continuously striving to optimize costs without compromising quality, making the search for affordable suppliers a top priority for many businesses.

Is titanium dioxide dangerous? Has it been linked to any health issues?
The vitaminB2@TiO2NPs were obtained at room temperature, by a method developed after trying several ratios of reactants. Briefly, 0.02 g of P25TiO2NPs were dispersed in 1 mL of ultra-pure water and stirred in a Vortex. Next, 200 μl of vitamin B2 dissolved in ultra-pure water (5.3 × 10−3 M) were added to 200 μL of P25TiO2NPs and the mixture was ultrasonicated for 1 hour to achieve a deep-yellow homogeneous suspension. The pellet obtained after centrifuging the suspension for 10 min at 4500 rpm was resuspended in ultrapure water, centrifuged again, and then lyophilized.
