  • China, known for its rapidly growing economy and industrial infrastructure, is also a major player in the global titanium dioxide market. With numerous titanium dioxide plants spread across the country, China has become one of the largest producers of this essential pigment.
  • 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.

  • Titanium dioxide, also known as titanium(IV) oxide or simply TiO2, is a white inorganic compound that has become an essential material for various industries. As a chemical compound, it possesses unique properties that make it highly valuable in numerous applications, ranging from paint manufacturing to sunscreen production.
  • Rubber products as a filler
  • One of the key features of the Tio2 BLR-895 range is its modular architecture, which allows for customization and scalability. Manufacturers can tailor the system to their specific needs, whether it involves simple repetitive tasks or complex processes requiring precision and reliability. The ability to upgrade and expand functionality as requirements evolve further underscores the future-proof nature of these systems.
  • Prof Matthew Wright, both a member of the FAF Panel and chair of EFSA’s working group on E 171, said: “Although the evidence for general toxic effects was not conclusive, on the basis of the new data and strengthened methods we could not rule out a concern for genotoxicity and consequently we could not establish a safe level for daily intake of the food additive.”

  • When selecting suppliers of conductive titanium dioxide, consider not only the present ability to meet your requirements but also their potential for future growth. Suppliers that continuously invest in technology upgrades, environmental sustainability practices, and customer service are poised to adapt to changing market dynamics and maintain their position as industry leaders.
  • Durabo White, 24.5 per cent zinc sulphide, 51 per cent barium sulphate, 18 per cent white clay, 5.5 per cent infusorial earth.

  • Recent analyses of food-grade TiO2 samples have found that a significant portion of particles may be within the nanoscale. These particles (also known as nanoparticles) range in size from 1 to 100 nm, where 1 nm equals 1 billionth of a metre (the width of a typical human hair is 80,000 to 100,000 nm).
