Therefore, that information is unavailable for most Encyclopedia.com content. A ruthenium-molybdenum alloy is said to be superconductive at 10.6 K (-440.6 F / -262.5 C). The element name comes from the Latin word ‘Ruthenia’.Ruthenia means Russia, which refers to the Ural Mountains of Russia, the original source of the platinum metal group ores. As an example, ruthenium-106 has been used to treat certain forms of eye cancer.Ruthenium is obtained by separating it from other platinum metals, such as platinum.One important use of ruthenium is in the manufacture of alloys. Overview
Ruthenium adds two properties to an alloy. This time, the discoverer was Russian chemist Gottfried W. Osann.

These alloys are used to make such things as furnace coils, electrodes for aircraft spark plugs and laboratory crucibles.For questions about this page, please contact,Thomas Jefferson National Accelerator Facility is managed by,Jefferson Science Associates, LLC for the U.S. Department of Energy. It is greyish-white in color and a member of the platinum family. Rhodium was discovered by William Hyde Wollaston, an English chemist, in 1803 shortly after his discovery of the element palladium.He obtained rhodium from a sample of platinum ore that was obtained from South America. An alloy is made by melting and mixing two or more metals. OSMIUM (REVISED) Second, it makes the alloy resistant to attack by oxygen and other materials.Ruthenium is most often combined with platinum or. Ruthenium is sometimes used in platinum alloys. Claus suggested calling the element ruthenium, after the ancient name of,Ruthenium is a hard, silvery-white metal with a shiny surface.

Overview It was discovered in 1844 and is found in ores that contain other metals from the platinum group. Sniadecki announced the discovery of the element in 1808. . It does not dissolve in most acids or in aqua regia.

Ruthenium catalysts may provide a way of changing light energy into electrical energy. It is estimated that there are only 5,000 tonnes of ruthenium on Earth and about 12 tonnes are obtained each year, mostly as a by-product of copper and nickel mining. These beta rays act somewhat like X rays. Note: This article, originally published in 1998, was updated in 2006 for the eBook edition. Ruthenium crystallizes in the hexagonal close-packed … Ruthenium’s atomic number is 44 and its atomic weight is 101.07. It is the 44th element on the periodic table and is represented by the symbol Ru. The mixture has properties different from those of the individual metals. Many authorities now call Claus the discoverer of the element.

Note: This article, originally published in 1998, was updated in 2006 for the eBook edition.Ruthenium belongs in the platinum group of metals. Note: This article, originally published in 1998, was updated in 2006 for the eBook edition. Radioactive isotopes are produced when very small particles are fired at atoms.

It is sometimes added to.A second important use of ruthenium is in catalysts. They promise to provide alternatives to platinum-based drugs for anticancer therapy. The elements in this group are named after the best known member of the group.Credit for the discovery of ruthenium is often given to Polish chemist Jedrzej Sniadecki (1768-1838). Its abundance in Earth's crust is about 0.0001 ppm. Discovered by.

Since 1979, when Cisplatin entered clinical trials, there has been continuing interest in alternative metal-based drugs. At only about 0.0004 parts per million, ruthenium is one of the rarest elements in the earth’s crust.
