The conjugation of vitamin C to the P25TiO2NPs was confirmed by UV-visible spectroscopy of lyophilized vitaminC@P25TiO2NPs suspensions. The typical absorbance peak of ascorbic acid at 265 nm was found. However, no further characterization was done because they did not show the expected protective effect against the photo-induced cell damage (Fig. 3).

Natural barite and anthracite containing more than 95% barium sulfate are mixed and fed at a ratio of 3:1 (mass). After being crushed to a diameter of less than 2cm, it enters the reduction furnace. The furnace temperature is controlled to be 1000-1200°C in the front section and 500-500 in the back section. 600°C, the reduction furnace rotates at a speed of 80 seconds per revolution, and the reaction conversion rate is 80% to 90%.
Although barium sulfate is almost completely inert, zinc sulfide degrades upon exposure to UV light, leading to darkening of the pigment. The severity of this UV reaction is dependent on a combination of two factors; how much zinc sulfide makes up the pigments formulation, and its total accumulated UV exposure. Depending on these factors Lithopone B301, Lithopone B311 powder itself may vary in shade over time, ranging from pure white all the way to grey or even black. To suppress this effect, a dopant might be used, like small amount of cobalt salts, which would be added to the formulation. This process creates cobalt-doped zinc sulfide. The cobalt salts help to stabilize zinc sulfide so it will not have as severe a reaction to UV exposure.
The global Lithopone market was valued at $169.8 million in 2019, and is projected to reach $218.6 million by 2027, growing at a CAGR of 3.30% from 2020 to 2027.
