Talk:Lead carbide

Does it exist?
I found only two reports of the existence of this product. One of them (2007) says that it can be obtained by reacting CaC2 with aqueous Pb acetate. Curiously this is just what a French 1956 book conjectured:
 * Peut-être existe-t-il un acétylure de formule PbC2 que l'on préparerait en faisant agir du carbure de calcium sur une solution d'acetate neutre de plomb?
 * Nouveau traité de chimie minérale: Volume 8 fasc. 3. Germanium, étain, plomb, par P. Bévillard [et al]. Masson, 1956

Could it be that the 2007 report is just a misquote of this conjecture as if it were a fact? --Jorge Stolfi (talk) 02:32, 11 November 2009 (UTC)

Can it exist?
The age of many of the citations and the advances made in organic and organometallic chemistry since those times suggest refinement is definitely needed in this article - but perhaps, in the science itself; what is missing from this article is a decent explanation as to why it doesn't exist if this is indeed the case. Considering the claim that what was formerly regarded as lead carbide was instead later found to be "an intimate mixture of lead and carbon", it seems likely that the ability of lead to form organic bonds with carbon is interfering with its ability to remain stable as an ionic carbide... but this doesn't have to be the case at all temperatures and pressures, does it? Although, I'm not sure why anyone would want to make something like that, other than just to try to solve an interesting mystery.Zaphraud (talk) 00:38, 28 January 2012 (UTC)

Claim by "Benito E. Abreu"
I temporarily removed this paragraph which was added by an anonymous editor:


 * However and in fact, Lead Carbide can be produced. Though in very small quantities by reacting lead(II) oxide PbO with carbon suboxide C3O2 at 3750°C in an inert gas (Argon or Krypton) atmosphere at extremely high pressure (125,000 psi or 862 MPa). This odd compound was produced by Benito E. Abreu in July 25, 2000, in a small laboratory in Santo Domingo, Dominican Repulic, with his own funding. To date, Mr. Abreu has produced 37.25 grams (1.314 oz.) of the compound. The project has been halted by him due to insufficient funds on his part and lack of sponsorship of the Dominican government.

This seems to be a self-reported original research. It would be exciting if true. However, I could not locate any "Benito E. Abreu" in the Dominican Republic through Google, nor any chemistry papers by such author. I hope that the editor who added that paragraph will come forth with additional information that would allow us to confirm this discovery. --Jorge Stolfi (talk) 07:48, 3 July 2012 (UTC)

Re. unusual synthesis
It has been theorized that pyrolytic carbon (covalently bonded graphene) if a BiPb eutectic is used with a strong (MV/um) DC bias under very high temperature in inert atmosphere might form PbC2 at the interface.

Also suggested: blue laser onto the carbon side might work due to the anomalous electron effects at the surface. Would probably only work with atomically thin layers but worth looking into as bulk PbC2 could be a HTSC candidate. — Preceding unsigned comment added by 185.3.100.7 (talk) 14:56, 26 January 2017 (UTC)
