Both 28B301 and 30B311 are white pigments with high brightness and excellent covering power. They are commonly used in coatings, plastics, rubber, and paper industries. The main difference between these two grades lies in their particle size distribution. 28B301 has a smaller particle size, resulting in higher opacity and better dispersion. On the other hand, 30B311 has a larger particle size, which makes it more suitable for applications that require good rheological properties.

The manufacturing process of lithopone involves several steps, including sulfide precipitation, grinding, classification, and packaging. During the sulfide precipitation stage, zinc sulfide and barium sulfate are reacted in an aqueous solution under controlled conditions to form a precipitate of lithopone. The precipitate is then washed, dried, and ground to the desired particle size distribution. Finally, the ground pigment is classified to remove any oversized or undersized particles and packaged for storage and transportation.

However, the market could not sustain these high prices and strived for equilibrium, causing the prices to fall. Further, after the complete removal of restrictions, the factories churned out products at a much faster pace than the market offtakes. Hence, the manufacturers reduced their quotations to maintain positive product movement in the market. The spot prices of titanium dioxide averaged around 2264 USD/MT in June’23 in the Chinese market.
