Some small test-tube research has shown that these nanoparticles are absorbed by intestinal cells and may lead to oxidative stress and cancer growth. However, other research has found limited to no effects (13Trusted Source, 14Trusted Source, 15Trusted Source).
Quality control is paramount for these manufacturers. They invest heavily in research and development to stay ahead of industry standards. Some have established their own testing facilities equipped with state-of-the-art instruments to conduct comprehensive material analysis. This ensures that each batch of titanium oxide rutile meets consistent specifications, from particle size distribution to color consistency and chemical purity.Titanium dioxide (TiO2) is a fine white powder or dust that occurs naturally. It was first intentionally produced for use as a white pigment in 1923.

From dyes to flavorings, many people are becoming increasingly aware of the ingredients in their food.

Moreover, titanium dioxide is also used in rubber formulations to improve the processing and curing properties of rubber compounds. It acts as a catalyst in the vulcanization process, speeding up the cross-linking of rubber molecules and enhancing the overall performance of the final product. This results in rubber products that are stronger, more flexible, and better suited for a wide range of applications.
Partial substitution of titanium dioxide in liquid paints
Another important application of titanium dioxide is in the production of sunscreen and other skincare products. Titanium dioxide is a key ingredient in many sunscreens due to its ability to reflect and scatter ultraviolet (UV) radiation, providing protection against harmful UV rays. Manufacturers of titanium dioxide for sunscreen products often use special coatings and surface treatments to enhance its UV-blocking properties.
For coating factories, incorporating good whiteness titanium dioxide rutile into their formulations ensures that the end product meets stringent quality standards. It helps to achieve a smooth, uniform finish that is resistant to chalking and fading, even when exposed to harsh weather conditions or UV radiation. Additionally, the durability of coatings containing this pigment is enhanced, extending the lifespan of painted surfaces and reducing maintenance requirements.
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.
Rutile grade titanium dioxide (TiO2) is a widely used white pigment that offers excellent whiteness, opacity, and UV protection. It is commonly used in various applications, including paints, plastics, coatings, and inks. One of the most popular rutile TiO2 grades is R1930, which is known for its high brightness, high dispersion, and good chemical resistance.
