翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Ruthenium ： ウィキペディア英語版 Ruthenium Ruthenium is a chemical element with symbol Ru and atomic number 44. It is a rare transition metal belonging to the platinum group of the periodic table. Like the other metals of the platinum group, ruthenium is inert to most other chemicals. The Baltic German scientist Karl Ernst Claus discovered the element in 1844, and named it after his homeland, the Russian Empire (one of Russia's Latin name is Ruthenia). Ruthenium usually occurs as a minor component of platinum ores; annual production is about 20 tonnes.〔(Summary. Ruthenium ). platinum.matthey.com, p. 9 (2009)〕 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 as a catalyst. ==Characteristics== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Ruthenium」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
