Calcium plumbate is an inorganic chemical that has been used extensively as an anticorrosive pigment in paints and coatings.[2][3][4][5] The formula is given as CaO3Pb,[6][7] but also is shown as CaO4Pb2 in other sources.[8][9] The compound has REACH restricted status due to the general toxicity of lead based compounds.[10]

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.[11]

Recent research indicates that it can be prepared by sol-gel methodology.[12]

Toxicology

Calcium plumbate and other lead paint additives have been known to cause lead poisoning for over 50 years.[13] The effects of paint containing calcium plumbate dust have likewise been studied and analytical techniques developed to assess lead content.[14][15] Studies also include finding calcium plumbate in soils and further possible bioaccumulation.[16] The demand for lead in all forms is decreasing worldwide,[17] 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.[18]
