dioxido de titanio anatase

Le lithopone a été découvert dans les années 1870 par DuPont. Il a été produit par la Krebs Pigments and Chemical Company, entre autres1. Il se faisait en différents grades, en fonction de la teneur en sulfure de zinc. Les qualités « bronze » et « or » contenaient 40 à 50 % de sulfure de zinc, ce qui les rendaient particulièrement couvrantes2. Bien que ce pigment ait atteint son pic de popularité autour de 1920, il s'en produisait encore annuellement plus de 220 000 tonnes en 1990. Il est principalement utilisé dans les peintures, les pâtes et les plastiques3.

One of the most notable characteristics of mixed crystal nano titania is its ability to absorb light across a wide range of wavelengths. This property makes it an excellent photocatalyst, capable of driving chemical reactions using only sunlight as the energy source. As such, it has found use in environmental remediation efforts, where it can help break down pollutants and harmful chemicals in water and air. Additionally, its high surface area-to-volume ratio allows for efficient adsorption of gases and liquids, making it useful in sensors and filters.

Inorganic pigment Lide powder, also known as zinc antimony white, is a mixed crystal of zinc sulfide and barium sulfate. It has many unique and excellent properties. Lide powder products form a series of products, such as high ZnS type, apparent treatment type, water dispersion. Type, light fastness, color type, etc., play an important role in industrial and agricultural production and daily life. Mainly used in coatings, paints, thermoplastics, thermosets, paper, etc., can replace some rutile by surface treatment or Ti0 2 coating.
