sailor moon[edit]

Does this article really need a reference to sailor moon at the very top? I know anime fans have reached 'important' positions within wikipedia but linking to those articles from the ones with scientific value seems like bad practice to me.

zirconia oxide?[edit]

The patents section refers to "zirconia oxide". Surely this should be either zirconia or zirconium oxide? 86.152.154.224 (talk) 13:03, 16 February 2009 (UTC)

Synthesis[edit]

This article mentions many uses of ZrO2 but not how it is actually made. If someone gets a chance to add its derivation from zircon that would be great. If I get done with finals and have some time I'll add it myself. Darkwraith (talk) 17:57, 10 December 2008 (UTC)

I think it would be useful to explain the actually mechanism behind the stabilization. An in depth disscusion of how the stabilizer effects the zirconia would be great. —Preceding unsigned comment added by 65.198.101.228 (talk) 14:27, 19 December 2008 (UTC)

Jewelry[edit]

Shouldn't someone mention how much they look like diamonds?

I think they mentioned that the two types of stone are difficult to disti--65.12.46.114 22:15, 25 September 2007 (UTC)nguish, and that most jewelers have a thermal conductivity tester for just that purpose. Reading Uncle Tungsten a while back, I noticed how Oliver Sacks was taught as a kid just how cold diamonds feel when pressed to one's lips; I wonder if this wouldn't be just as accurate a test for thermal conductivity, but without the fancy instruments.--Joel 23:12, 29 May 2005 (UTC)

Article name[edit]

Zirconium dioxide would be a better name for this article, or at least more in keeping with Wikipedia:Naming conventions (chemistry). I would do the move, except that this article seems to have come from there. What do people think? Physchim62 22:29, 24 August 2005 (UTC)

Yes, it seems to already have been moved (back) to ziconium dioxide. Now I'd like to ask: "shouldn't it be 'zirconium oxide'?" Apparently this is what it is listed under in Chemical Abstracts. Apparently the oxidation state of Zr is always +4 (but see the discussion at Talk:Zirconium), so is it necessary to specify stoichiometry if there's no alternative? — DIV 128.250.204.118 09:34, 16 November 2006 (UTC)

great article[edit]

Great article on zirconia, covers all of the high points of the material. -ceramic engineer—Preceding unsigned comment added by 68.184.91.110 (talkcontribs)

It should also be mentioned that it's used in the manufacture of ceramic knives. http://en.wikipedia.org/wiki/Ceramic_knife — Preceding unsigned comment added by 69.253.39.117 (talk) 15:26, 1 September 2011 (UTC)

high temperature conductivity[edit]

"Zirconia is one of few compounds that actually becomes conductive at high temperatures"

Increasing conductivity with temperature is normal for most materials (taking insulators and semiconductors together as being a majority), and that's almost a definitive property of a semiconductor. Mainly metals tend to go the other way, so it's not really correct to say zirconia is one of "few compounds" that do this when in fact it's one of a very large number of common compounds with the same property. Zirconia is often considered to be a "wide bandgap" semiconductor (Eg~5-ish eV), and it shares a lot of properties with diamond (Eg~5.5 eV) because their bandgaps are similar.
