message: 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.  137.53.85.122 (talk) 18:57, 7 February 2008 (UTC)
replies: text: 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)

message: 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.--68.156.55.2 13:26, 23 Jun 2005 (UTC)

replies: text: 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)

message: The article says "Some metals, such as lead and tin, are believed not to form carbides under any circumstances." How is that possible when tin carbide (SnC) is for sale here: https://www.americanelements.com/tin-carbide? DEm (talk) 12:17, 2 October 2018 (UTC)
thread_title:  Tin Carbide 

message: Under the headline "Chemical classification of carbides", you can find the words "Examples include". It is very unclear what exactly these examples are examples of!
Right above, there is a list of 4 different classifications of carbides according to chemical bond. Are the examples listed examples of the 4th type, since this is last? 🤷🏻‍♀️ Or are they examples from each type listed above?... Quark538 (talk) 07:31, 20 October 2022 (UTC)
