Chemical compound

Calcium plumbate is an inorganic chemical that has been used extensively as an anticorrosive pigment in paints and coatings. The formula is given as CaO3Pb, but also is shown as CaO4Pb2 in other sources. The compound has REACH restricted status due to the general toxicity of lead based compounds.

Manufacture

It is usually manufactured by the reaction of calcium oxide (CaO) and lead oxide (PbO) at high temperature in the presence of excess oxygen.

Recent research indicates that it can be prepared by sol-gel methodology.

Toxicology

Calcium plumbate and other lead paint additives have been known to cause lead poisoning for over 50 years. The effects of paint containing calcium plumbate dust have likewise been studied and analytical techniques developed to assess lead content. Studies also include finding calcium plumbate in soils and further possible bioaccumulation. The demand for lead in all forms is decreasing worldwide, though the use of calcium plumbate and other heavy metal compounds in cement and concrete is subject to recent research and the specific toxicology studied.
