Comment[edit]

Thermite is made from iron(III) oxide NOT iron(II) oxide. RJFJR 00:30, 12 December 2005 (UTC)

Sorry, my mistake. RJFJR (talk) 18:32, 19 June 2008 (UTC)

Wüstite[edit]

Wüstite is the mineral form of Iron(II) oxide. I wonder whether these articles should be merged? --Donar Reiskoffer 09:04, 19 January 2006 (UTC)

I oppose this proposal. We have hundreds of minerals such as halite which could in principle be merged with the chemical compound article such as sodium chloride. However the focus of the articles are different (geology/mining vs. chemical). Although both these are stubs at the moment, I expect the chemistry one at least to grow into a full length article in time. The only occasion when I would think it OK to merge is if wüstite is an obscure mineral of little interest to geologists. Walkerma 06:29, 2 February 2006 (UTC)
Oppose for the same general reasons. It is normal on Wikipedia to have seperate articles on the chemical and the mineral, and these articles are usually written by different people. Physchim62 (talk) 19:10, 2 February 2006 (UTC)
Oppose as well. The Iron(III) oxide is dissociated with Hematite; i don't see how wüstite should be any different. As far as my knowledge goes, wüstite is much more common as a component of meteors, and thus may especially warrant an article for itself. SReynhout 07:14, 23 February 2006 (UTC)
Neutral. Google search reveals that quite often the term wustite actually refers not to mineral, but to chemical compound Fe1-xO. Anyway, there is no big rush. (As a side note, I also noticed that the confusion of ferric/ferrous oxide is all over google, including .edu domain). mikka (t) 01:41, 23 February 2006 (UTC)

Ferrous vs. Ferric Oxide[edit]

Suggest that a section be added that explains physical and chemical differences between ferrous and ferric oxide. Asod001 04:35, 2 August 2006 (UTC)

Well, people don't call it "ferrous oxide" anymore so now you won't have to worry about it. Mr. Guye (talk) 01:45, 5 February 2014 (UTC)

Pigment uses[edit]

There are many references to FeO being used as a pigment. However bearing in mind that it oxidises so readily it seems likely that it is often added as a known "contaminant" of industrially produced iron oxides. FeII may persist in glasses/enamels. Does anyone have cosmetic production, glassmaking/enamelling knowledge?
As for tattoo ink, there are some references in reputable journals to black FeO being produced by laser irradiation of tattoos. Personally I would be more than surprised if this was correct, as I would assume that the black colouration produced was due to Fe3O4 rather than FeO. Does anyone have some good chemical knowledge of this area?--Axiosaurus (talk) 10:24, 19 April 2008 (UTC)

Properties[edit]

  • Is it magnetic?
  • Can we expand that it energetically oxidizes to Fe2O3 (the note that it is pyrophoric in the info box).18:15, 19 June 2008, User:RJFJR

Metallic Iron Oxide at Earth's Core?[edit]

(Since they talk about rock salt structure, I suppose it's FeO...)BBC: Metal undergoes novel transition under extreme pressure -- megA (talk) 16:12, 20 December 2011 (UTC)

Still a hypothesis, but i have added a citation.(mercurywoodrose)75.61.139.47 (talk) 17:00, 22 January 2012 (UTC)

Reactions[edit]

I believe that the reactions section needs a little work. It is lacking detail and appears inadequate. An idea of what to add could be detail on the resulting materials. Mr. Guye (talk) 02:10, 5 February 2014 (UTC)
