[edit] Information Sources
Some of the text in this entry was rewritten from Los Alamos National Laboratory - Zirconium. Additional text was taken directly from USGS Zirconium Statistics and Information, from the Elements database 20001107 (via dict.org), Webster's Revised Unabridged Dictionary (1913) (via dict.org) and WordNet (r) 1.7 (via dict.org). Data for the table were obtained from the sources listed on the subject page and Wikipedia:WikiProject Elements but were reformatted and converted into SI units.
[edit] Talk
I do not have time to rewrite this article much of the information is incomplete, out-date and some incorrect. The following sentence is dead wrong:
"Compounds containing zirconium are encountered relatively rarely by most people and their inherent toxicity is low."
Zirconium compounds are used as an active ingredient in underarm antiperspirants commonly used in the North American market. This means zirconium compounds are commonly encountered by people.
In addition, the last sentence of the introduction is wrong. Zirconium is used by the nuclear industry because it absorbs few neutrons compared to other materials, as indicated later on in the article.
If I was sure about it, I'd say why it is difficult to get it free from Hafnium. I assume it is because they are in the same period of the table, and therefore rather similar in chemical properties? How is it actually accomplished? Midgley 00:45, 13 January 2006 (UTC)
- I moved in some data from Zircaloy. Feel free to expand, please. --Shaddack 03:46, 13 January 2006 (UTC)
[edit] Oxidation state(s)
In a literature database there are 6 references (all since 1993) that mention Zirconium(III) propoxide: the implication is Zr has an oxidation number of +3 in this compound. Any comments?? — DIV 128.250.204.118 09:28, 16 November 2006 (UTC)
