Samarium Hydride (SmH2~3)-Powder
Characteristic
Samarium hydride is a compound of hydrogen and yttrium. It is considered to be a part of the class of rare-earth metal hydrides. 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 has the oxidation state +3. Compounds of samarium (II) are also known, most notably the monoxide SmO, monochalcogenides SmS, SmSe and SmTe, as well as samarium (II) iodide. The last compound is a common reducing agent in chemical synthesis. Samarium has no significant biological role but is only slightly toxic.

Application
The major commercial application of samarium is in samarium–cobalt magnets, which have pone of the highest resistances to demagnetization known.
Samarium-149 has high cross-section for neutron capture (41,000 barns) and is therefore used in the control rods of nuclear reactors.
Other applications of samarium include catalysis of chemical reactions, radioactive dating and X-ray lasers.
Package
Vacuum pumping and argon protection, 500g or 1000g / bottle.
