An acetylene gas lamp is no lime-light. see for a description was a lime-light is.


The text in this section refer to WC as exhibiting a "rock-salt" structure (face-centered cubic), yet the data table describes WC as exhibiting a hexagonal close-packed structure. There are incompatible and need attention. (talk) 18:57, 7 February 2008 (UTC)Alex Cranson

Agreed. I need to revisit this summary table- it is confusing. If you are confident please take a shot at it - I will put it on my to do list. It all hinges on the packing of the metal atoms in the interstitial which differs from the metal-- perhaps this just unnecessarily complicated - the naming of close packing etc. is confusing for the uninitiated reader - perhaps a simpler list of actual structures without an attempt to summarise would be easier to understand. --Axiosaurus (talk) 10:35, 8 February 2008 (UTC)

What is a carbide[edit]

I'm not sure if this article's definion of a carbide is correct. It says it's a polyatomic ion (C2) but I thought that a carbide was simply a salt of carbon combined with a metal. I'm not a chemist, so I don't feel comfortable editing this main part of the article. Does anybody have any input on this? — Brim 07:09, Feb 11, 2005 (UTC)

"carbide" is not calcium carbide, it's just a short name that people use instead. I work at the last U.S. owned calcium carbide manufacturer (there are only 2 operational calcium carbide furnaces left in the U.S.) and we call it carbide as do most of our customers, but we all know it's really calcium carbide.-- 13:26, 23 Jun 2005 (UTC)

Honestly, this page should not be called Carbide, it should be calcium carbide.-- 13:30, 23 Jun 2005 (UTC)

I came to this page looking to find out what Calcium Carbide is and I found NOTHING. Could someone clean it up so that it provides a bit more information? There is actually a link in the article to Calcium carbide that does nothing but bring you back to this page.

Is the picture (bluish rock) calcium carbide?HappyVR 14:58, 15 April 2006 (UTC) The calcium carbide that I saw about 1944 was a much darker color, likely due to impurities such as bits of unreacted coke. It looked just like the small size pieces of crushed rock that were commonly used for driveways in that era. The carborundum stone = silicon carbide looked like a flat rectangular solid cut from a larger rock, but possibly it was fine sand with a binder. The tungsten carbide I have seen, looked like metal. I presume all three are hard, strong and brittle, but that may not be true of all the 100 or so carbides. More detail about properties would be helpful. (talk) 19:02, 21 March 2012 (UTC)

Disambiguation required?[edit]

Nokia (for whom I work for) has a set of software tools called Carbide (please see The tools are generally referred to as the Carbide product family, with individual releases denoted by their target technology or use -- for instance, C++ products are called Carbide.c++. Although it doesn't currently exist, I would like to start a page that overviews the product family and points to individual product pages. How should this be resolved?

Name your hypothetical article something like: Carbide (software)
Then, at the top of this (the Carbide) article, place a "disambiguation" line that is similar to this:
For the Nokia software toolset, see Carbide (software).

Calcium carbide- still important industrially[edit]

While production US, Europe and Japan has reduced significantly production in China is very high, many millions of tons pa. --Axiosaurus (talk) 18:11, 21 September 2008 (UTC)

Excellent point. And an important one since making this material is environmental threat but China has lots of coal and few regulations, so they are apparently readopting acetylene-based technologies that were abandoned in the west. I think that they use the acetylene to make vinyl monomers. I will get back to the carbide article by the way.--Smokefoot (talk) 20:47, 21 September 2008 (UTC)


The link redirects to a different compound, Li2C2, and I can't find a relevant page to link to, so I'm removing the link. Jojofunny123 (talk) 11:22, 3 April 2012 (UTC)
