Bismuth vanadate
A strong yellow pigment made from bismuth and vanadium oxides
No single value: Bismuth vanadate is a material, and its colour varies. The background shows its family, yellow.
Bismuth vanadate is a vivid yellow compound used mainly as a pigment and in photocatalysis. It is a mixed-metal oxide, found rarely in nature, but now produced for its colour and technical uses. Its pigment form is valued for its brightness and ability to cover surfaces well.
- A bright yellow pigment with excellent coverage
- Made from bismuth, vanadium, and oxygen
- First made in 1924, widely used since the 1980s
- Studied for use in solar-driven water splitting
- Occurs rarely in nature as several minerals
What colour is Bismuth vanadate?
Bismuth vanadate is a synthetic yellow pigment with a strong, bright colour. It can show a slight greenish cast and is known for its ability to hide surfaces well. As a pigment, it stands out for its clarity and strength compared to many other yellows. In nature, it appears only rarely as minerals, but most of what is used today is made in laboratories.
Where does Bismuth vanadate come from?
The compound was first made in the early twentieth century, with its earliest known synthesis described in a pharmaceutical patent from 1924. Its use as a pigment became widespread decades later. The name comes from its chemical makeup, combining bismuth and vanadium with oxygen.
How is Bismuth vanadate made?
Bismuth vanadate can be produced by mixing solutions under controlled pH conditions, sometimes with molybdenum, or by heating bismuth and vanadium oxides together at high temperatures. The process can be adjusted to create different crystal structures, which affect its properties as a pigment.
Where Bismuth vanadate is used
This pigment is mainly used for its colour in paints and coatings, where its brightness and coverage are valued. Beyond art, it is studied for its ability to act as a photocatalyst, helping split water or break down pollutants when exposed to light.
