The most important application of Samarium is Samarium-Cobalt magnets which have a very high permanent magnetization. Uses of Samarium. It occurs in monazite to the extent of 2.8%. Samarium cobalt magnets certainly come into their own at high operating temperatures and will begin to outperform special … Radioactive 153 Sm is used in the treatment of cancers. While misch metal containing about 1% of samarium metal, has long been used, samarium has not been isolated in relatively pure form until recently. Abundance and Isotopes Liquid-liquid and ion-exchange techniques are used for the commercial separation and purification of samarium. Samarium is also used as an absorber in nuclear reactors. Samarium is the hardest member of the cerium group of rare earth metals. They are used to decompose plastics, dechlorinate pollutants, dehydrate and dehydrogenate ethanol along with many other uses. Samarium with cobalt is used to make new permanent magnet material. Samarium oxide is also used in infrared absorbing glass. It is also used in the cores of carbon arc-lamp electrodes. Samarium oxide (samaria) is used as a catalyst for the dehydration and dehydrogenation of ethanol.Samarium oxide is also used in infrared absorbing glass. For example, it can be added to glass for color or special optical (light) properties. Fun Facts!!!! Samarium is used to dope calcium fluoride crystal for use in optical lasers … Samarium (low valent) Low valent metal compounds are common reducing agents. Radioactive 153 Sm is used in the treatment of cancers. Samarium is used to dope calcium chloride crystals for use in optical lasers. Sm-147 has been bombarded with Ca-40 to produce the short-lived radioisotopes Pb-182. Samarium doped calcium chloride crystals, Sm doped YAG and samarium doped quartz are used in optical lasers [1, 18, 22]. The origin of name: From smarskite, a mineral ; Samarium is also used as an absorber in nuclear reactors. Health Hazards Samarium in the form of oxides is used for making special infrared adsorbing glass. Health Hazards Samarium exists in three allotropic (structural) forms. The samarium compound samarium iodide is an important reducing and coupling agent in organic synthesis. Samarium Sm 153 lexidronam has been found to be effective at palliating pain and reducing opioid analgesic use, and associated with mild and transient adverse events in prostate cancer patients with hormone-refractory disease and metastatic bone disease. Samarium 153 is used in injections for the treatment of painful bone metastases [9] in lung, breast, prostate and other types of cancer patients [5]. It was discovered by Paul Emile Lecoq de Boisbaudran in the year 1879. Samarium definition is - a silvery-white lustrous metallic element of the rare-earth group that is used especially in permanent magnets. Samarium with cobalt is used to make new permanent magnet material. Samarium isotopes are used in various applications. Sm-144 is used for the production of the therapeutic radioisotope Sm-145. Samarium oxide (samaria) is used as a catalyst for the dehydration and dehydrogenation of ethanol.Samarium oxide is also used in infrared absorbing glass. Samarium in the form of oxides is used for making special infrared adsorbing glass. In common with other lanthanides, samarium is used in carbon arc lighting for studio lighting and projection. Samarium oxide (samaria) is used as a catalyst for the dehydration and dehydrogenation of ethanol. Radiopharmaceuticals are radioactive agents that may be used to find and treat certain diseases or to study the function of the body's organs. What Are Samarium Cobalt Magnets Used for? Today, samarium is primarily obtained through an ion exchange process from monazite sand ((Ce, La, Th, Nd, Y)PO 4), a material rich in rare earth elements that can contain as much as 2.8% samarium. It is widely used in the dehydration and dehydrogenation of ethanol. Samarium Sm 153 lexidronam injection is a radiopharmaceutical. Samarium is a metallic element with a bright silver luster. Samarium oxide finds specialised use in glass and ceramics. Samarium Sm 153 lexidronam injection is a radiopharmaceutical. It is widely used in the dehydration and dehydrogenation of ethanol. The metal is conveniently prepared by metallothermic reduction of its oxide, Sm 2 O 3, with lanthanum metal, followed by distillation of the samarium metal, which is one of the most volatile rare-earth elements. Samarium is found along with other members of the rare-earth elements in many minerals, including monazite and bastnasite, which are commercial sources. Sm-148 has been used to study the giant monopole resonance while Sm-149 has been used in a filter for polarizing thermal neutrons. Samarium oxide has been used in optical glass to absorb the infrared. Samarium cobalt magnets work over a wider temperature range, have superior temperature coefficients and have much greater corrosion resistance. Due to excellent properties, we hardly can see any samarium cobalt magnets in daily supplies. It is also used in infrared absorbing glass and as a neutron absorber in nuclear reactors. Samarium oxide is used in glass and ceramics [1]. A laser is a device for producing very bright light of a single color. Uses Samarium has some uses similar to those of other rare earth elements. Samarium compounds are also very important in the chemical industry.
