Manufacturers of white titanium dioxide pigment play a critical role in ensuring product quality and consistency. They employ cutting-edge technology to refine the pigment's particle size and shape, crucial factors that determine its performance in end products They employ cutting-edge technology to refine the pigment's particle size and shape, crucial factors that determine its performance in end products They employ cutting-edge technology to refine the pigment's particle size and shape, crucial factors that determine its performance in end products They employ cutting-edge technology to refine the pigment's particle size and shape, crucial factors that determine its performance in end productswhite titanium dioxide pigment manufacturers. Advanced techniques such as chlorination or sulfate processes are used, each with its own set of advantages and challenges. The chlorination process, for instance, yields high-purity TiO2 but involves more complex and costly procedures.

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 a preferred technical solution, 3⁄40 2 is added to the Lide powder emulsion of the metathesis reaction step, and the mass fraction of 3⁄40 2 added is 10 to 33%, and the lithopone emulsion is desulfurized (mainly hydrosulfate ion or Elemental sulfur), slowly added 3⁄40 2 until the lithopone emulsion is colorless and transparent. The obtained sulfate ion can be recycled and reused in the production process. The chemical reaction equation is: 43⁄40 2 + HS— + OH— → SO/— + 5H 2 0
