Some of the text in this entry was rewritten from Los Alamos National Laboratory - Ruthenium. Additional text was taken directly from the Elements database 20001107 (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.
Added some material on ruthenium CVD. This "review" isn't complete and I'll probably return to it to add more on the various beta-diketonates tried. ALD of Ru had been done by Aaltonen et al at the University of Helsinki, and that should be added. Also, the applications of ruthenium thin films are very poorly described and should be clarified.

Bad Dot diagram
The dot diagram for this article states that it is in the Noble Gasses group, whereas ruthenium is a transitional metal in the platinum group. —The preceding unsigned comment was added by 220.127.116.11 (talk • contribs) .
- The Lewis structure describes valence electrons and is unrelated to the ground state configuration. Femto 10:36, 30 April 2006 (UTC)
- As a transition metal, it has more than that one available as valence electrons. Femto 10:52, 4 May 2006 (UTC)
Scientific American June 13, 2012 has an article about ruthenium as a possible artificial photosynthesis catalyst. While not efficient (at this point) the ability to split both water and carbon dioxide makes ruthenium very interesting! ~~Cite error: The opening

Is ruthenium rare in the universe as a whole, or is it simply rare in the Earth's crust? Does the platinum group concentrate in the Earth's core?--Syd Henderson 03:26, 10 October 2006 (UTC)
Are you sure that the activity figures are expressed in Curies? A Curie is HUGE, 1 Ci/gram beign defined as the activity of pure radium! The values quoted appear very far from "safe" to me, even those after 20 years of quarantine time... --18.104.22.168 11:38, 6 November 2006 (UTC)
- A curie is defined as 37 billion disintegrations per second. The curie was originally a comparison of the activity of a sample to the activity of one gram of radium, which at the time was measured as 37 billion disintegrations per second. A radioactive sample that has an activity of 74 billion disintegrations per second, has an activity of 2 curies. When more accurate techniques measured a slightly different activity for radium, the reference to radium was dropped. - http://www.epa.gov/radiation/understand/curies.htm

The text states that Ruthenium is "white"; the info box states that it is "silver-white", and the picture looks "dark gray" to me. Stifynsemons 08:00, 22 December 2006 (UTC)
- Well, I, for one, have to admit that I'd never looked at the picture. Good call, it's not a very good picture at all of Ruthenium and I would have trouble recognising it as such. Perhaps a better picture could be found. As to the actual color of massive Ruthenium it is "silver-white" in color, the term "white" by itself usually being reserved for pure Silver. Yes, this is confusing, unless one has had the opportunity to see all of the precious metals in their massive form in one place at the same time, then it becomes quite clear what is meant. The distinctions can be obscured by surface treatments such as polishing which are the forms most commonly encountered, as in jewelry et al. Drrocket 16:43, 22 December 2006 (UTC)
Anyone work with bulk Ru? I can provide an optical micrograph or a very cropped micrograph of a ruthenium thin film, but that may or may not be appropriate. Globalistgirl (talk) 05:39, 18 January 2008 (UTC)
- Ruthenium's spot price may be increasing because hard disc storage devices use it as a coating and the newer technology for the disc storage is requiring a thicker coating. TBone007 00:25, 25 March 2007 (UTC)
Just found this article that 'chip' resistors use Ruthenium. Can this application be included?

I can confirm the Ruthenium is being used to make new hard drives. Source: JP Morgan research on the PGM industry. Hence the price movement.
Ruthenium is also used in electrochromic applications at an increasing rate. It's becomming a 'hot' area so demand is also increasing. I remember paying 3$ per gramm for RuCl3 two years ago. Now, it's 15$ per gramm!!!!!!!!!!!! This will hinder research of new electrochromes - cost too much now...

Ruthenium is a rare transition metal belonging to the platinum group of the periodic table. Like the other metals of its group, ruthenium is inert to most other chemicals. The Baltic German scientist Karl Ernst Claus discovered the element in 1844, and named it after Ruthenia. Ruthenium usually occurs as a minor component of platinum ores; annual production is about 20 tonnes. Most ruthenium produced is used for wear-resistant electrical contacts and the production of thick-film resistors. A minor application of ruthenium is its use in some platinum alloys, and, like many elements located near platinum, is used in automobile catalytic converters.
