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]
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]
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.
