  • The demand for 30-50nm TiO2 powders stems from their enhanced surface area to volume ratio, which amplifies their reactivity and photocatalytic efficiency. This attribute is paramount in applications such as photovoltaics, where these nanoparticles can boost energy conversion rates in solar cells. In the field of environmental remediation, they serve as potent catalysts for degrading pollutants under light exposure. Furthermore, the exceptional transparency and refractive index of TiO2 nanoparticles make them ideal for high-performance coatings and paints, offering improved durability and aesthetic appeal.

  • 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.
