  • Lithopone B301 is highly valued for its excellent hiding power and brightness, making it an ideal choice for high-quality paints and coatings. Its particle size distribution ensures seamless integration into different mediums, enhancing the overall performance of the end product. On the other hand, Lithopone B311 distinguishes itself with increased chemical stability and resistance to fading, attributes that are crucial for applications requiring longevity and exposure to harsh environments.
  • The European market sees players like Evonik Industries and Kemira, both recognized for their cutting-edge TiO2 technology. Their products not only enhance the concrete's appearance but also contribute to its durability and resistance against environmental factors.
  • However, other countries like the United States, Japan, and Germany also have notable lithopone producers. These companies, although operating on a smaller scale, often offer higher quality products with specialized grades tailored to specific industries. For instance, American company Huber Engineered Materials and German-based Merck KGaA are renowned for their high-performance lithopone products.
  • Furthermore, rutile TiO2's inherent thermal stability makes it an ideal candidate for high-temperature applications such as ceramics and glass coatings. It also finds use in solar cells, where its ability to withstand extreme temperatures and resist UV degradation is crucial for the longevity of the device.
  • Scrap zinc or concentrated zinc ores are dissolved in sulfuric acid, the solution is purified and the two solutions are reacted. A heavy mixed precipitate results that is 28 to 30% zinc sulfide and 72 to 70% barium sulfate.
