  • Manufacturing barium sulfate involves a meticulous process, typically starting with the extraction of barite, a naturally occurring mineral rich in barium sulfate. These mines, often located in China, India, and the United States, are the primary source of raw material for global barium sulfate factories. Once extracted, the barite undergoes purification to remove impurities like silica, iron, and clay, ensuring high-grade barium sulfate production.

  • 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.

  • The production of lithopone begins with the synthesis of its core components. Zinc sulfide is typically derived from the reaction between zinc oxide (ZnO) and hydrogen sulfide (H2S). This chemical reaction occurs at high temperatures, resulting in a fine, white powder that serves as one of the primary constituents of lithopone.

  • In addition to its outstanding properties, lithopone has excellent stability, weather resistance and chemical inertness. This makes it suitable for a wide range of applications, even under harsh environmental conditions. You can rely on lithopone to stand the test of time, maintaining its luster and performance for years to come.

  • Chemical Stability: Lithopone powder exhibits good chemical stability, ensuring long-term performance and durability in a variety of harsh environments.

  • Chloride process. This process requires a high titanium feedstock. Rutile is reacted with hydrochloric acid to produce titanium tetrachloride, which can be hydrolyzed with steam or oxidized with air to render the dioxide. A rutile form of titanium dioxide is obtained.

  • In its 2016 opinion, the ANS Panel recommended new studies be carried out to fill the gaps on possible effects on the reproductive system, which could enable them to set an Acceptable Daily Intake (ADI ). Uncertainty around the characterisation of the material used as the food additive (E 171) was also highlighted, in particular with respect to particle size and particle size distribution of titanium dioxide used as E 171.   

  • It is important for manufacturers to maintain strong relationships with their customers and partners to ensure a smooth supply chain and efficient distribution of titanium dioxide rutile. This includes collaborating with raw material suppliers, distributors, and end-users to address any issues or concerns, as well as to gather feedback and insights for product improvement and development.
  • The journey into this factory is like stepping into a futuristic world where technology and nature coexist harmoniously. The air is crisp and clean, devoid of the usual pollutants one might associate with heavy industry. This is no accident; the factory has invested heavily in state-of-the-art pollution control systems that ensure emissions are minimized, while also recovering and recycling materials wherever possible.

  • Spectrophotometric methods are also employed, where the absorbance of light by a sample is measured after a color-forming reaction specific to sulfate. By comparing the absorbance values to a calibration curve prepared with standards of known TiO2 content, the concentration of sulfate can be accurately determined.

  • Furthermore, chemical product manufacturers contribute to the development of new technologies and materials. Advancements in plastics, composites, and other materials have led to lighter, stronger, and more durable products across various industries. This has resulted in improved transportation, construction, and consumer goods that enhance our daily lives.
  • The manufacturing process of high-quality Rutile Titanium Dioxide in specialized factories is a complex and precise operation. These factories employ cutting-edge technology and rigorous quality control measures to ensure the optimal purity and performance of the final product. The process typically involves mining, chemical treatment, calcination, and finally, crystal formation. Each step is crucial in determining the whiteness, opacity, and durability of the TiO2.

  • The gastrointestinal tract is a complex barrier/exchange system, and is the most important route by which macromolecules can enter the body. The main absorption takes place through villi and microvilli of the epithelium of the small and large intestines, which have an overall surface of about 200 m2. Already in 1922, it was recognized by Kumagai, that particles can translocate from the lumen of the intestinal tract via aggregation of intestinal lymphatic tissue (Peyer’s patch, containing M-cells (phagocytic enterocytes)). Uptake can also occur via the normal intestinal enterocytes. Solid particles, once in the sub-mucosal tissue, are able to enter both the lymphatic and blood circulation.

  • Overall, titanium dioxide is a valuable white pigment that plays a crucial role in many industries. Its unique properties and versatility make it an essential ingredient in a wide range of products, from paints and plastics to paper and personal care items. As technology continues to advance, the demand for titanium dioxide is expected to grow, driving further innovation and development in the industry.
