In the leather industry, it is one of the sulfide-based white pigments. It is also used in the production of linoleum floorings.
When selecting a supplier for titanium dioxide powder, it is essential to consider factors such as product quality, price, delivery time, and customer service. Many suppliers offer customized solutions to cater to specific requirements, such as special particle sizes or surface treatments. It is also crucial to ensure that the supplier has appropriate certifications and adheres to relevant regulations and standards.Coronavirus-related shutdowns in the first half of the quarter prompted forcible measures at several small-scale ilmenite factories in China and India, subsequently exacerbating the Titanium supply problem. The chemical's tight supply condition was extended until the end of the quarter, as few participants were heard holding cargoes in expectation of an exceptional surge in its seasonal demand.
Furthermore, the concept of green chemistry is gaining traction in the Chinese TiO2 industry. Companies are exploring eco-friendly production methods, such as using chloride-route technology that generates less wastewater and has a lower environmental impact compared to the traditional sulfate route.Titanium dioxide nanoparticles may accumulate and cause DNA damage
Pigment grade titanium dioxide is produced at a much larger particle size than nano grade. It is used as a colourant to whiten and brighten product formulations. Nano grade titanium dioxide is manufactured into very fine (nano) particles and is transparent and colourless. It is commonly used in sunscreens to provide effective protection from potentially harmful UV rays.
Like all our products and ingredients, the titanium dioxide we use meets the highest standards for quality and safety, respecting all applicable laws and regulations as well as meeting our own safety assessments.

Resumo–Este artigo discute a descoberta de litopônio fosforescente em desenhos de aquarela do artista americano John La Farge datados de entre 1890 e 1905 e a história do litopônio na indústria de pigmento no final do século XIX e início do século XX. Apesar de ter muitas qualidades desejáveis para o uso em aquarela branca ou tintas a óleo, o desenvolvimento do litopônio como um pigmento de artistas foi prejudicado por sua tendência a se escurecer na luz solar. Sua disponibilidade para e uso por parte de artistas ainda não está clara, uma vez que os catálogos comerciais dos vendedores de tintas geralmente não eram explícitos na descrição de pigmentos brancos como algo que contém litopônio. Além disso, o litopônio pode ser confundido com o branco de chumbo durante o exame visual e sua fosforescência de curta duração pode ser facilmente perdida pelo observador desinformado. O litopônio fosforescente foi documentado em apenas um outro trabalho até hoje: uma aquarela de Van Gogh. Além da história da manufatura do litopônio, o artigo detalha o mecanismo para a sua fosforescência e sua identificação auxiliada pela espectroscopia de Raman e espectrofluorimetria.

Introduction Good whiteness titanium dioxide rutile is a critical component for coating factories due to its exceptional optical properties. The term good whiteness refers to the pigment's ability to reflect a broad spectrum of visible light, resulting in a bright, clean appearance. This characteristic is particularly important in applications where a uniform and consistent color is desired, such as in paints, plastics, and paper manufacturing.Although barium sulfate is almost completely inert, zinc sulfide degrades upon exposure to UV light, leading to darkening of the pigment. The severity of this UV reaction is dependent on a combination of two factors; how much zinc sulfide makes up the pigments formulation, and its total accumulated UV exposure. Depending on these factors the pigment itself can vary in shade over time, ranging from pure white all the way to grey or even black. To suppress this effect, a dopant may be used, such as a small amount of cobalt salts, which would be added to the formulation. This process creates cobalt-doped zinc sulfide. The cobalt salts help to stabilize zinc sulfide so it will not have as severe a reaction to UV exposure.

Titanium dioxide holds exceptional significance as a white pigment due to its superior scattering capabilities, remarkable chemical stability, and non-toxic nature. Among all white pigments, it surpasses others in terms of its ability to scatter light effectively. Consequently, titanium dioxide stands as the most significant inorganic pigment, accounting for the highest quantity in usage. The majority part of the global production of ilmenite and rutile is dedicated to the production of TiO2 pigments. The remaining portion is utilized for the manufacturing of titanium metal and in the production of welding electrodes.
The production process of titanium dioxide powder mainly includes ore selection, acid decomposition, hydrolysis, washing, drying, calcination, and crushing. During this process, strict quality control is required to ensure that the final product meets the relevant standards. Moreover, environmental protection measures must be taken during the production process to minimize the impact on the environment. Food grade calcium carbonate is another commonly used grade that is approved for use in the food industry. It is used as a food additive in products such as baked goods, breakfast cereals, and dairy products. Food grade calcium carbonate must meet strict standards set by regulatory bodies to ensure its safety for consumption
