Cosmetic Use[edit]

No mention of cosmetic use or controlled environment production of iron oxides, so I added it. I also added a link to the U.S. Geological Survey. I'm new to this. Hope you don't mind my inclusions. LorraineP 16:30, 22 June 2007 (UTC)

I added a link to my site, L.A. Minerals, because the information about cosmetic grade iron oxides was pulled from there. No I didn't link for SEO purposes. We are already on page 2 on Google for search term 'mineral makeup'.


This article seems misleading. In most cases, oxides of commonly used metals such as iron, nickel, chromium and aluminium, under conditions where they are stable, protect the metals against further corrosion. This explains the stability of non-noble metals such as stainless steel, titanium and aluminium. It is hydroxides, chlorides, etc. that cause harmful corrosion. Iron that has been heated so that it becomes coated with oxides tends to be protected from rust. David R. Ingham 01:28, 14 October 2006 (UTC)

--agreed on this point. I think at some point a revamp of this article is necessary, as I also find the characterizations of the iron oxides erratic at best. CharonZ 11:41, 16 April 2007 (UTC)

As there are already articles for most of the iron oxides I propose that one should only give a rough entry (e.g. crystal structure, colour etc.) to each of the oxides and then link with the other articles. This article would look more homogenous that way. —The preceding unsigned comment was added by CharonZ (talkcontribs) 16:41, 23 April 2007 (UTC).

I agree. The first paragraph is a mess. Way to0 many links and too much info. Second, why are there links to the hydroxides as well?Kyanite 01:10, 22 May 2007 (UTC)

Ok, change it back if you disagree, but im going to remove non relevent information. Not withholding: Iron Hydroxides.Kyanite 01:15, 22 May 2007 (UTC)

Actually it doesn't make sense to remove iron hydroxides, as hydroxides are really only a nother subspecies of iron oxides. I fear that has to be revertedCharonZ 15:47, 22 May 2007 (UTC)

I'm curious how none of you thought to include the rust on an old car as an example of iron oxide, or of the red that stains Australian and Martian rocks. 12:51, 28 September 2007 (UTC)

Ferric Oxides as an sulphur reduction agent[edit]

Ferric oxides are increasingly used in biogas plants for the purpose of reducing the contents of sulphur. Sulphur is very harmful for internal combustion engines used in Biogas plants and driven by biogas. I will welcome a more deeply explanation for this topic and this use of ferric oxides. —Preceding unsigned comment added by (talk) 11:56, 10 January 2008 (UTC)


Two formulæ appear next to some species in the list. At present this is confusing, and not explained. — DIV ( (talk) 09:38, 26 March 2008 (UTC))

oxides in oxygen busters ?[edit]

Hi, I found out from the technical sales guy at Dessicare that the oxygen busters that they use in food products have iron in them which oxidises over time and then becomes Iron Oxide II and Iron Oxide III - I would like to know if this can be added to soil in my garden (and everyone's gardens) and if it is fine to do so. The main purpose is to promote some reuse of the oxygen busters (but cutting them open to get the iron out) as the are so prolific now and I hate that they cannot be recycled at all. Any help appreciated. Plmoknqwerty (talk) 09:56, 24 September 2012 (UTC)
