- The Chinese lithopone B311 manufacturing industry is characterized by its competitiveness, technological advancement, and commitment to quality. The companies featured in this article are at the forefront of this industry, offering a diverse range of products and services that cater to the needs of customers worldwide. As the demand for lithopone B311 continues to grow, these manufacturers are well-positioned to capitalize on emerging opportunities and maintain their leadership position in the market.
- Lithopone, a blend of zinc sulfide and barium sulfate, is renowned for its exceptional properties. It boasts high refractive index, superior lightfastness, and excellent heat resistance—qualities that make it particularly suitable for rubber compounding. When integrated into rubber formulations, lithopone imparts a pristine white color, which not only improves the aesthetic appeal of the final products but also serves functional purposes.
We use titanium dioxide as a colourant in some home care products, including in laundry detergents, dishwasher tablets and toilet blocks.
Calcium carbonate and titanium dioxide are two important minerals that are widely used in various industries. While they share some similarities, they also have distinct differences when it comes to their manufacturing processes and applications.

In a 2019 study published in the journal Nanotoxicology, researchers recreated the first phase of digestion in mice and fed them titanium dioxide, then examined whether accumulation occurred in the organs. Researchers wrote: “Significant accumulation of titanium was observed in the liver and intestine of E171-fed mice; in the latter a threefold increase in the number of TiO2 particles was also measured. Titanium accumulation in the liver was associated with necroinflammatory foci containing tissue monocytes/macrophages. Three days after the last dose, increased superoxide production and inflammation were observed in the stomach and intestine. Overall, [this] indicates that the risk for human health associated with dietary exposure to E171 needs to be carefully considered.”
Lithopone: an alternative to titanium dioxide

Some websites maintain titanium dioxide is inferior to zinc oxide, another mineral sunscreen ingredient whose core characteristics are similar to those of titanium dioxide. The reality is that titanium dioxide is a great broad-spectrum SPF ingredient and is widely used in all manner of sun-protection products. What gets confusing for some consumers is trying to decipher research that ranks sunscreen ingredients by a UV spectrum graph. By most standards, broad-spectrum coverage for sunscreen ingredients is defined as one that surpasses 360 nanometers (abbreviated as “nm” - how the sun’s rays are measured). Titanium dioxide exceeds this range of protection, but depending on whose research you read, it either performs as well as or slightly below zinc oxide.
In a 2020 study published in the Journal of Trace Elements in Medicine and Biology, researchers conducted an in vitro experiment to analyze the effects of TiO2 nanoparticles on a human neuroblastoma (SH-SY5Y) cell line. The scientists evaluated “reactive oxygen species (ROS) generation, apoptosis, cellular antioxidant response, endoplasmic reticulum stress and autophagy.” The results showed that exposure to the nanoparticles “induced ROS generation in a dose dependent manner, with values reaching up to 10 fold those of controls. Nrf2 nuclear localization and autophagy also increased in a dose dependent manner. Apoptosis increased by 4- to 10-fold compared to the control group, depending on the dose employed.”
In Europe, the downstream paints and coatings sector presented weak demand in front of the titanium dioxide manufacturers, and thus, the titanium dioxide price trend experienced a gradual decline in its trajectory. Additionally, the pressure of inflation and increasing bank interest rates lowered the spending appetite of consumers which had an adverse effect on the titanium dioxide price trends. Further, the export and import of titanium dioxide were also caught under the negative influence of the poor economic conditions of the market.
Titanium dioxide goes into many industrial and consumer products. It makes paper white and bright, it keeps plastics and rubber soft and flexible, and helps remove harmful emissions from car exhaust, among many other uses. In the drug industry, it's a key ingredient in pill capsules and tablet coatings to keep the medicine inside from being affected by sunlight.
Par ailleurs, dès lors que l'on recherche une certain transparence dans les travaux artistiques, son pouvoir opacifiant et son pouvoir dégradant des couleurs pas trop élevés le désignent pour remplacer le dioxyde de titane trop opaque et trop dégradant (§ Des Liants et des couleurs aux éditions EREC)


To ensure the optimal precipitation percentage, it is important to carefully control these factors during the precipitation process. For example, a higher concentration of titanium sulfate will typically result in a higher precipitation percentage, but may also lead to the formation of impurities. On the other hand, a lower pH of the reaction mixture can promote the precipitation of titanium hydroxide, but may also result in a lower precipitation percentage.
