Ruthenium (BioDeep_00000033098)

描述信息

Ruthenium, also known as ru, is a member of the class of compounds known as homogeneous transition metal compounds. Homogeneous transition metal compounds are inorganic compounds containing only metal atoms,with the largest atom being a transition metal atom. Ruthenium can be found in a number of food items such as italian sweet red pepper, broccoli, potato, and dill, which makes ruthenium a potential biomarker for the consumption of these food products. Ruthenium can be found primarily in blood, cerebrospinal fluid (CSF), and urine. 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 Russian-born scientist of Baltic-German ancestry and a member of the Russian Academy of Science Karl Ernst Claus discovered the element in 1844 at Kazan State University in Russia and named it after the Latin name of his homeland, Rus. Ruthenium is usually found as a minor component of platinum ores; the annual production is about 20 tonnes. Most ruthenium produced is used in wear-resistant electrical contacts and thick-film resistors. A minor application for ruthenium is in platinum alloys and as a chemistry catalyst .
A polyvalent hard white metal, ruthenium is a member of the platinum group. Like the other metals of the platinum group, ruthenium is inert to most chemicals. Most ruthenium 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.[Wikipedia]
