CAS: 12060-58-1 | Sm2O3

Samarium(III) oxide is used in optical and infrared absorbing glass to absorb infrared radiation. It finds use as a neutron absorber in nuclear power reactors to control the reaction. It is also used as a catalyst for the dehydration of primary alcohols to aldehydes or ketones. It forms samarium perchlorate when treated with perchloric acid, which is used as a reference material for checking the wavelength scale of a spectrophotometer in the range of 200 to 500 nm.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
