The vitaminC@P25TiO₂NPs, on the other hand, were obtained through an optimized method based on Mallakpour et al. [27]. Initially, 0.02 g of P25TiO₂NPs were dispersed in 1 mL of ultrapure water and stirred in a Vortex. Next, 100 μL of HCl (0.01 M) were added (pH 2) to 100 uL of P25TiO₂NPs to avoid gel formation. Then, 100 μL of vitamin C dissolved in ultra-pure water (5.0 × 10⁻³ M) solution were added to the mixture and was ultrasonicated for 30 min. Finally, vitamin C was added in excess to gain a beige-orange color suspension, and the ultrasonication continued for another 30 min. The pellet obtained after centrifuging the suspension for 10 min at 4500 rpm was resuspended in ultrapure water, centrifuged again, and then lyophilized.

Lithopone factory : What should we pay attention to when purchasing?

Lithopone B301, Lithopone B311 powder is also widely applied in paints and enamels

Additionally, market demand plays a significant role in determining lithopone pigment prices. Industries such as construction, automotive, and consumer goods have been experiencing fluctuations in demand, influencing the pricing dynamics. In periods of high demand, prices may increase as suppliers adjust to the market trends. Conversely, during downturns or oversupply situations, prices may decrease, providing opportunities for buyers to purchase at more favorable rates.
