Gravimetric analysis is a method of quantitative chemical analysis in which a substance is converted into a stable compound of known composition, and the mass of this compound is then measured. This technique offers a high level of precision and is particularly useful in determining the concentration of materials within complex mixtures. The gravimetric determination of titanium dioxide typically involves a series of well-defined steps, which include precipitation, filtration, washing, drying, and weighing.

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.

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 the pigment itself can vary in shade over time, ranging from pure white all the way to grey or even black. To suppress this effect, a dopant may be used, such as a 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.
