Samarium (III) oxide ? Strategic Elements
Samarium oxide is a chemical compound of the elements samarium and oxygen and belongs to the group of metal oxides.

Samarium (III) oxide is an odorless, fine white-yellowish solid in powder form that is insoluble in water. Samarium oxide is moderately soluble in strong mineral acids and slightly hygroscopic. It occurs in a monoclinic and a cubic crystal structure, with the cubic shape being more stable and common.

Samarium (III) oxide is used in the optics and glass industries, e.g. it is used in infrared radiation absorbing glass. In organic chemistry, it catalyzes the reaction of acyclic primary alcohols to aldehydes and ketones. Another application is the creation of other samarium salts and special alloys such as Sm-Co alloy.
Samarium-cobalt magnets have a very high permanent magnetization, which is approximately 10,000 times that of iron. Only modern neodymium magnets are stronger. They also have a higher resistance to demagnetization and are still stable even in temperature ranges around 700 ° C.
