2. Barite calcination method A solution of barium sulfide is prepared. The sulfuric acid and zinc oxide are reacted, purified by adding potassium permanganate and zinc powder, and compressed to obtain a zinc sulfate solution. Then, the prepared barium sulfide solution is mixed and subjected to a metathesis reaction to obtain a mixture of zinc sulfide and barium sulfate, and then the precipitate is subjected to pressure filtration, calcination, wet grinding, drying, and pulverization to obtain a zinc white product.

Firstly, TiO2 is commonly used as a white pigment in plastic products. Its high refractive index and ability to scatter light across the visible spectrum provide excellent opacity and brightness to plastic materials. This makes it an essential component in producing white or light-colored plastics, such as packaging materials, household items, and toys. The addition of TiO2 not only enhances the aesthetic appeal of these products but also improves their overall quality by increasing their durability and resistance to UV radiation.
