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 which produce beams of light intense enough to burn metal or bounce off the moon.
