Samarium Oxide Powder (Sm2O3), CAS 12060-58-1
Samarium oxide powder (Sm2O3) is a pale yellow powder that is commonly used as a raw material for the production of other samarium compounds, such as samarium metal, samarium fluoride, and samarium nitrate.
Samarium oxide is insoluble in water, but soluble in acids. It has a high melting point of 2,340 °C and a high thermal conductivity, making it useful in high-temperature applications. It is also used as a dopant in the production of solid-state lasers and in the manufacturing of specialized glass compositions.
Samarium oxide powder should be stored in a cool, dry place, away from heat sources and incompatible materials. Proper protective equipment, such as gloves and safety goggles, should be worn when handling this material.

Application
Samarium Oxide also called Samaria, Samarium has a high neutron absorption capacity, Samarium Oxides have specialized uses in glass, phosphors, lasers, and thermoelectric devices. Calcium Chloride crystals treated with Samarium have been employed in lasers that produce beams of light intense enough to burn metal or bounce off the moon. Samarium Oxide is used in optical and infrared absorbing glass to absorb infrared radiation. Also, it is used as a neutron absorber in control rods for nuclear power reactors. The Oxide catalyzes the dehydration of acyclic primary alcohols to aldehydes and ketones. Another use involves the preparation of other Samarium salts.
