Samarium(153Sm) lexidronam(chemical name Samarium-153-ethylene diamine tetramethylene phosphonate, abbreviated Samarium-153 EDTMP, trade name Quadramet)
As the first commercially viable rare earth permanent magnet material, Samarium Cobalt(Sm-Co) is considered to still be the premium material for many high performance applications.
Samarium Cobalt has the greatest magnetic strength together with higher temperature range that makes it perfect for applications requiring very large strength in hot environments.
According to two new studies, a radioactive version of the element samarium decays much more quickly than previously thought, and different versions of
Misch metal containing about one percent of samarium has long been used, but it was not until recent years that relatively pure samarium has been isolated through ion exchange processes, solvent extraction techniques, and electrochemical deposition.
In permanent magnet DC(PMDC) motors these field coils are replaced with strong rare earth(i.e. Samarium Cobolt, or Neodymium Iron Boron) type magnets which
George de Hevesy and Max Pahl, he discovered that the natural long-lived isotopes of samarium primarily decay by emission of alpha particles.
Alex Shlyakhter uses samarium ratios from the Oklo prehistoric natural nuclear fission reactor in Gabon to show that some laws of physics have remained unchanged for over two billion years.
As with the other lanthanides, samarium compounds are thought to have low to moderate toxicity,
However, a by-product of the fractional crystallization purification of neodymium was a mixture of samarium and gadolinium that acquired the name of"Lindsay Mix" after the company that made it.
bonded neodymium magnets or samarium cobalt magnets) and iron bearings.
Samarium was first discovered spectroscopically in 1853 by Swiss chemist Jean Charles Galissard de Marignac by its sharp absorption lines in didymium, and isolated in Paris in 1879 by French chemist Paul Émile Lecoq de Boisbaudran from the mineral samarskite((Y,
writing his doctoral thesis on the"Radioactivity of ordinary elements, especially samarium and neodymium: method of detection" under the supervision of Wendell Mitchell Latimer.
the known chemical elements) known as the rare-Earth metals(notably samarium and neodymium) also make good magnets.
with a doctoral thesis on the“Radioactivity of ordinary elements, especially samarium and neodymium: method of detection” under the supervision of Wendell Mitchell Latimer.
For example, Samarium(149) captures a neutron to become Samarium(150),
Samarium is a rare earth metal, with a bright silver luster, that is reasonably stable in air; it ignites in air at 150 °C. Even with long-term storage under mineral oil, samarium is gradually oxidized, with a grayish-yellow powder of the oxide-hydroxide being formed.
What is Samarium?
Samarium cobalt magnets are brittle.
Standard tolerances for Samarium Cobalt magnets are+/-.
