Lithopone’s historical significance is further accentuated by the advancements and modifications that followed its inception. The 1874 patent by J.B. Orr, for instance, ushered in a new white pigment—Orr’s Zinc White. This innovation was attained by co-precipitating zinc sulfate and barium sulfide, followed by a calcination process. Further refinements marked the subsequent decades, the most notable being the enhancement of lightfastness achieved in the 1920s by introducing small amounts of cobalt salts before calcination.

In conclusion, the production of titanium dioxide is a complex and multi-step process that requires careful control of various parameters. Despite the challenges, the demand for this versatile pigment continues to grow, driven by its widespread applications and the increasing demand for environmentally friendly products. As technology advances and environmental concerns grow, the titanium dioxide industry will continue to evolve, seeking new ways to meet the demands of a changing world.

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.”

 2) Purification: Add ammonium persulfate to the final immersion solution for one-time oxidation and iron removal, and add activated carbon to adsorb arsenic and iron co-precipitation to achieve the purpose of removing arsenic. Add the polyacrylamide coagulant to separate and filter before separation. The sulfide solution is added to the solution to remove sulfur, and the separated filtrate obtained by the separation is replaced with zinc powder to remove the remaining impurities to obtain a zinc sulfate ammonia complex liquid, which is used in the next step;

    1. Despite these challenges, importers of titanium dioxide have a unique opportunity to drive innovation and sustainability in their industries. By collaborating with producers and end-users, importers can help develop more efficient production processes and responsible sourcing practices. They can also facilitate the adoption of alternative technologies and materials that reduce the environmental impact of titanium dioxide production and use.
