Charge of Fe?

Since carbide ion is 4- (when there is one carbon), what are the charges on the 3 Fe ions? Are they +1,+1 and +2? Or is there an error?RSido 01:25, 14 November 2007 (UTC)[reply]

I'm not convinced that you can assign clear oxidation numbers to the atoms in this structure. You might as well assign 0 to all atoms and think of it as an alloy! --Itub 19:22, 14 November 2007 (UTC)[reply]

Composition in Weight Ratios

There is no mention of the composition in terms of percentage weight of carbon and iron for cementite in eutectoid structures. This is a pretty important number for applications in material science, the application with which information abut this substance is primarily concerned. I just think if people are looking up this article, it may very well be to find this value (its the reason I looked it up). Anyone have any thoughts regarding this? If no one has any complaints I'll add it within a day or two.Tracorn (talk) 07:21, 8 May 2009 (UTC)[reply]
