Samarium Oxide is a highly insoluble thermally stable material suitable for glass, optic and ceramic applications. Samarium oxide is prepared by thermal decomposition of samarium carbonate, nitrateoxalate or sulfate or by burning the metal in air or oxygen at a temperature above 150 °C.


Samarium oxide forms salts upon evaporation and crystallization by dissolving in mineral acids. Samarium Oxide is generally immediately available in most volumes. Samarium is used in laser applications and for its dielectric properties and in filter glass on Nd:YAG solid state lasers. It forms stable titanate compounds with useful dielectric properties. Oxide compounds are not conductive to electricity. Rare Earth oxide compounds are basic anhydrides and can therefore react with acids and with strong reducing agents in redox reactions. Samarium oxide is also available in pelletspiecessputtering targetstablets, and nanopowder.


Typical and custom packaging is available. 


 Uses and applications                                                                                                                                       infrared radiation. Also, it is used as a neutron absorber in control rods for nuclear power reactors. The oxide catalyzes dehydration of acyclic primary alcohols to aldehydes and ketones. Another use involves preparation of other samarium salts.
