Samarium Oxide Micron Powder

Samarium oxide is a chemical compound consists of samarium metal and oxygen with the chemical formula of Sm2O3. Samarium oxide appears as pale-yellow powder. It has very high melting point which is 2335oC. Samarium oxide may be prepared by thermal decomposition and by burning the metal in air or oxygen at a temperature above 150 °C. Samarium oxide micron powder is used in high permittivity ceramics for dielectric resonators and substrates. In carbon dioxide gas sensors, samarium oxide powders are used as solid state electrolyte. Besides, samarium oxide powders are used to make composite with cerium oxide powders and this composite can be used in solid oxide fuel cells. Also, samarium oxide powders are used in nuclear reaction piles as structural and shielding materials, as a catalyst for the dehydration of ethanol. Samarium oxide is a key ingredient and additive for any number of ceramic products, where it increases absorption of infrared light. The unique chemical traits of samarium oxide make it ideal for sensor devices to detect toxic gases such as ammonia, ethanol, and methanol. Like many oxides, samarium oxide has been the subject of extensive research as a potential material for solid oxide fuel cells, with promising results.
