what is samarium used for

Samarium metal is used to dope calcium fluoride crystals in order to use them for optical lasers. Samarium-149 has high cross-section for neutron capture and is therefore used in the control rods of nuclear reactors. One radioactive isotope of samarium is used in medicine, and the element is also used in magnets and some metal … Neodymium-iron-boron magnets are stronger than this samarium-cobalt magnet, but it's still a … most abundant element in the Earth crust. 870 samarium used products are offered for sale by suppliers on Alibaba.com, of which rare earth & products accounts for 4%. Multiple Choice A) $0 B) $(15,000) C) $25,000 D) $45,000 Answer: A) You need to subscribe to get the answer. It is also used in nuclear reactors, some ceramics, and lighting. Samarium-cobalt magnets replaced the more expensive platinum-cobalt magnets in the early 1970s. These can be used for various applications. It occurs in monazite to the extent of 2.8%. The Advantages of Neodymium Magnets in Headphones Neodymium magnets are lighter and smaller than other magnets, making them a perfect choice for earbuds and headphones. Some cancer treatments use the radioisotope samarium-153 to alleviate severe pain due to metastasis. Industrially, samarium is used as a dopant in some lasers, and it also appears as an additive in glass which is designed to absorb infrared energy. A commonly used name for samarium Sm 153 lexidronam is Sm 153 ethylenediaminetetramethylene phosphonic acid or Sm 153-EDTMP. Samarium-153 Samarium-153 (153 Sm) has a half-life of 46.3 hours, undergoing β − decay into 153 Eu. Samarium’s main use is in samarium-cobalt alloy magnets for headphones, small motors and pickups for some electric guitars. Samarium isotopes are used in various applications. Manufacturing - In general, the elements are melted together and milled into a powder that is dry-pressed to shape in the presence of a magnetic field. Rare-earth element, any member of the group of chemical elements consisting of three elements in Group 3 (scandium [Sc], yttrium [Y], and lanthanum [La]) and the first extended row of elements below the main body of the periodic table (cerium [Ce] through Currently, they are used for such things as hospital MRI machines, airplanes, boats, cars, speaker systems and earbuds and headphones. Samarium 153 has been used in trials studying the supportive care of Pain, Lung Cancer, Breast Cancer, Prostate Cancer, and Metastatic Cancer. The complex samarium Sm 153 lexidronam is used in the palliative treatment of bone pain associated with osteoblastic metastatic bone lesions, administered intravenously. Read more about the prescription drug SAMARIUM SM-153 In clinical studies employing planar imaging techniques, more QUADRAMET® (samarium sm 153 lexidronam) accumulates in osteoblastic … Samarium is used as a catalyst in certain organic reactions: the samarium iodide (SmI 2) is used by organic research chemists to make synthetic versions of natural products. They keep their ferromagnetism at temperatures up to 700 o C. (3) As a result of their ability to operate at high temperatures, SmCo magnets are used … Information and translations of SAMARIUM in the most comprehensive dictionary definitions resource on the web. Osteoblastic metastases are a type of bone metastasis where new bone tissue grows rapidly. Meaning of SAMARIUM. Samarium is primarily utilized in the production of samarium-cobalt (Sm 2 Co 17) permanent magnets.It is also used in laser applications and for its dielectric properties. In its usual oxidized form, samarium is added to ceramics and glasses where it increases absorption of infrared light.
