Lead carbide is a hypothetical chemical compound of carbon and lead. ==Production== Lead and elemental carbon do not normally combine, even at very high temperatures.〔 Modern literature on lead carbide is almost non-existent. J. F. Durand reported in 1923 the synthesis of lead carbide from calcium carbide CaC2 by treatment with an aqueous solution of lead(II) acetate Pb(CH3COO)2, but this result was not reproduced.〔 William A Frad (1968), ''Metal Carbides''. In Harry Julius Emeléus, ''Advances in inorganic chemistry and radiochemistry.'' volume 12, page 213. (Online version ) at books.google.com, accessed on 2010-01-17. 〕〔 J. F. Durand (1923), Comptes Rendus... cited by W. A. Frad. 〕 A recent textbook repeats this claim, and describes it as a green powder with formula PbC2 that is decomposed by hydrochloric acid HCl to acetylene C2H2 and lead(II) chloride PbCl2.〔 R. K. Sharma (2007) ''Chemistry of Hydrides and Carbides.'' Discovery Publishing House, New Delhi. ISBN 81-8356-227-2. 〕 A compound analyzed as lead carbide PbC2 has also been obtained accidentally, as a thin layer (about 10 μm thick) on the inner wall of a graphite crucible that had been used to heat a lead-bismuth eutectic alloy for 100 hours at 1073 K in a helium atmosphere.〔 P.
