Why no natural crystals?[edit]

Why won't they form a crystalline structure, by nature? lysdexia 04:04, 24 Nov 2004 (UTC)

  • row two elements, but these have to bond with non filled ? type molecular bonds, at extreme bond angles, so in the end, it is extremely short bond distances, so very hard to break apart, but there are intermediate stages of the crystal that are much more stable in non-thin film form, and therefore, the only time the process can occur is seemingly as a thin film on a substrate that acts as a catalyst with the correct activation energy. Well that is my take on it, but I am not an expert. --[[User:Ctrl build|Ctrl_buildtalk ]] 05:31, 24 Nov 2004 (UTC)
    • pi type.
They don't form a crystal structure easily because other phases (such as cyanogen) are preferred at the high temperatures needed to react carbon and nitrogen. Catalysis is difficult as well; other approaches, such as decomposing tricyanamide, N(CN)3 tend to break up the crystal structure as it forms, resulting in amorphous C3N4 (which is not at all rare, by the way). Hell, the first time c-BN was synthesized, they just tried random things until something worked. I'd expect that here too. Scythe33 (talk) 04:18, 1 March 2008 (UTC)[reply]

Speedy delete tag[edit]

I've removed the speedy delete tag - there are sources available to verify some of the article content. Addhoc 14:17, 30 October 2007 (UTC)[reply]

Fake[edit]

I think this is a phoney idea made by someone with a sense of humor. Funny joke but not acceptable here and a big hoax.--Iceglass 15:52, 4 November 2007 (UTC)[reply]

I have to agree with him. This should go to uncyclopedia---- Koolo (talk) 17:05, 16 November 2007 (UTC)[reply]
I've added a link to an article snippet from Nature News, a reliable independent source, talking about beta carbon nitride. If it is indeed a hoax, very concrete evidence is going to be needed to overturn the current evidence referenced in the article. Please do not speedy or tag this article as a hoax again without providing such concrete proof. Ioeth (talk contribs friendly) 17:44, 16 November 2007 (UTC)[reply]
