Ruthenium is a chemical element with atomic number 44. Ruthenium is in the platinum group of metals. Ruthenium is a hard, gleaming white metal with a glossy surface. The boiling point of Ruthenium is around 3900-4150 Celsius and the melting point of Ruthenium is about 2300-2450 Celsius. Density of Ruthenium is 12.41 grams for each cubic centimeter.
Ruthenium metal is moderately inert. Ruthenium does not dissolve in most acids. Ruthenium generally reacts with materials that don't respond with acid separately. Ruthenium does not react with oxygen at room temperatures. At higher temperatures Ruthenium combines with oxygen.
Ruthenium is one of the rarest elements on Earth and occurs in platinum ores. Ruthenium has seven isotopes.
Ruthenium is gotten by isolating it from other platinum metals, for example, platinum, palladium, and osmium. These metals are generally acquired as by-products during the refining of nickel metal. They are then isolated from each other by chemical reactions.
Ruthenium tetroxide is exceptionally dangerous to health. Its exhaust is irritating to the skin, eyes, and respiratory tract.
Applications:
Ruthenium is used in the manufacture of alloys. Ruthenium alloys are hard and resistant to oxygen.
Ruthenium is used in electrical contacts, devices for measuring temperatures, medical instruments.
Ruthenium is also used in jewelry.
Ruthenium is added to titanium to make the metal more resistant to rusting.
Ruthenium is used as a catalyst (in changing light energy into electrical energy).
Ruthenium is used in chip resistors, solar cells.
Ruthenium is also used in catalysts for ammonia and acetic acid production.
