Bismuth Pigments

Greenish yellow pigments based on bismuth orthovanadate [14059-33-7], BiVO4, mar­ket introduction 1985, represent a class of pigments with interesting coloristic prop­erties. They extend the familiar range of yellow inorganic pigments, e. g. iron yellow, chrome yellow, cadmium yellow, nickel titanium yellow, and chromium titanium yel­low. In particular they substitute the greenish yellow lead chromate and cadmium sulfide pigments. In the Color Index they have been registered as C. I. Pigment Yellow 184.

The actual volume of bismuth vanadate pigments is estimated to be around 12001 a-1 and is steadily increasing.

Bismuth-containing special effect pigments based on platelet-shaped crystals of bismuth oxide chloride (bismuth oxychloride, BiOCl) have been known for a long time (see Section 5.3.1.3).
