Samarium is a chemical element with symbol Sm and atomic number 62. It is a moderately hard silvery metal that slowly oxidizes in air. Being a typical member of the lanthanide series, samarium usually assumes the oxidation state +3. The element was isolated in 1879 by Lecoq de Boisbaudran from the mineral samarskite, named in honour of a Russian mine official, Colonel Samarski, and which therefore gave samarium its name. Samarium is used as a catalyst in certain organic reactions: the samarium iodide (SmI2) is used by organic research chemists to make synthetic versions of natural products. Reaction of samarium with water. The silvery white metal samarium is quite electropositive and reacts slowly with cold water and quite quickly with hot water to form samarium hydroxide, Sm(OH)3, and hydrogen gas (H2). Samarium is the fifth most abundant of the rare elements and is almost four times as common as tin. It is never found free in nature, but in contained in many minerals, including monazite, bastnasite and samarskite. Samarium containing ores are found in USA, China, Brazil, India, Australia and Sri Lanka. A samarium–cobalt (SmCo) magnet, a type of rare earth magnet, is a strong permanent magnet made of an alloy of samarium and cobalt. They are generally ranked similarly in strength to neodymium magnets, but have higher temperature ratings and higher coercivity. They are brittle, and prone to cracking and chipping. Samarium is a bright, fairly hard, silvery white metal. It is one of the lanthanide rare earth metals. It is stable in air at normal temperatures, but ignites in air when the temperature is 150 oC or higher. Samarium is used to dope calcium chloride crystals for use in optical lasers. It is also used in infrared absorbing glass and as a neutron absorber in nuclear reactors. Samarium oxide finds specialised use in glass and ceramics. Isotopes are two or more forms of an element. Three of samarium's naturally occurring isotopes are radioactive—samarium-147, samarium-148, and samarium-149. A radioactive isotope is one that breaks apart and gives off some form of radiation. One radioactive isotope of samarium, samarium-153, is used in medicine.
