Lead chromate Chemical Properties,Uses,Production

Physical Properties

Lead chromate
Lead chromate  is used in the production of commercial lead chromate pigments, such as Primrose Chrome Yellow, Light Chrome Yellow and Medium Chrome Yellow, containing 65-89% lead chromate (IARC 1990).
Lead chromate(VI) is also used in the preparation of green pigments such as chrome green or green cinnabar, in which it is mixed with Prussian blue (qq.v.). It is also listed by the Colour Index as a component of Pigment Green 15.

Occurrence and Uses

Lead chromate occurs in nature as the minerals, crocoite and phoenicochroite. It is an important pigment of lead used in oil paints and water colors. It is used for printing textiles and coloring porcelain.


Lead chromate(VI), PbCrO4, also known as plumbous chromate, was first synthesised around 1800, with its potential use as a pigment first reported by Berthollet and Vauquelin in 1804. According to Vauquelin (1809), it was prepared by adding lead acetate or lead nitrate to potassium chromate, and the shade of the precipitate could be varied (from yellow to orange or red) by adjusting the acidity/alkalinity of the products. Lead chromate( VI), which occurs naturally as the rare mineral crocoite (Rutley, 1988), is known as the pigment chrome yellow (qq.v.). It is listed by the Colour Index (1971) as CI Pigment Yellow 34 (CI 77600). The commercial manufacture of the pigment was largely influenced by the availability of suitable raw materials (usually in the form of the abundant mineral chromite, FeCr2O4). The earliest record of the use of chrome yellow is in a painting by Sir Thomas Lawrence dated prior to 1810 (Kühn, 1969). Sources of the pigment are reported by Harley (1982, citing Field, 1809) to be available by 1814-15, with Bollman (1769-1821) cited as the first commercial manufacturer in England, with production beginning around 1814-16.


Lead chromate is found naturally in minerals crocoite and phoenicochroite. It also is readily prepared by adding a soluble chromate such as sodium or potassium chromate to a solution of lead nitrate, lead acetate or other soluble lead(II) salt in neutral or slightly acidic solution:
Pb2+ + CrO4 → PbCrO4
The yellow precipitate is filtered, washed and dried.


Moderately toxic by intraperitoneal route. The effects, however, are mild from oral intake. Occupational exposure may cause cancer. There is sufficient evidence of carcinogenicity in animals and humans.

Chemical Properties

Lead chromate is an orange or orange-yellow crystalline solid or powder.


It is used in chemical analysis of organic substances. pigment for paints and inks; in oil and water colors; printing fabrics, decorating china and porcelain; in chemical analysis of organic substances; in traffic paints.


Lead chromate (PbCrO4) is found in nature as yellow crystals in the mineral crocoite. It can be produced by reacting lead chloride and sodium dichromate. It is a popular and safe yellow pigment.


Lead chromate, “chrome yellow” PbCrO4, yellow precipitate, by reaction of soluble lead salt solution and sodium dichromate or chromate solution.Used as a pigment; basic lead chromate, red solid, insoluble, formed by heating lead chromate and sodium hydroxide solution.

Health Hazard

Lead chromate is a suspected human lung carcinogen and can cause chronic lead poisoning.

Potential Exposure

Lead chromate is used to make paint pigments for wood and metal
