Samarium Oxide (CAS#12060-58-1)
Samarium oxide is a highly insoluble and thermally stable samarium source with specialized applications in glass, ceramics, phosphors, lasers, and thermoelectric devices.
Samarium and its compounds are also widely used as catalysts and chemical reagents, particularly for promoting the dehydration of acyclic primary alcohols to produce aldehydes and ketones. In its common oxidized form, samarium can be incorporated into ceramics and optical or infrared-absorbing glass to enhance infrared radiation absorption. It is additionally utilized as a neutron absorber in control rods for nuclear power reactors.
Furthermore, samarium oxide serves as a precursor for the preparation of other samarium salts through dissolution in mineral acids followed by evaporation and crystallization. It can be produced by burning samarium metal in air or oxygen above 150 °C, or by the thermal decomposition of samarium carbonate, nitrate, oxalate, or sulfate.

Product Application of Samarium Oxide (CAS#12060-58-1)
Samarium oxide, also known as samaria, possesses a high neutron absorption capacity. It is widely applied in glass, phosphors, lasers, and thermoelectric devices. Samarium-treated calcium chloride crystals have been used in laser systems capable of generating highly intense light beams strong enough to burn metal or reflect off the moon.
In addition, samarium oxide is incorporated into optical and infrared-absorbing glass to enhance infrared radiation absorption. It serves as a neutron absorber in control rods for nuclear power reactors. The oxide also functions as a catalyst for the dehydration of acyclic primary alcohols to form aldehydes and ketones. Furthermore, it is used as a precursor in the preparation of other samarium salts.
