About Samarium

This chemical element is a light grey color metal extracted from a mineral named samarskite which, in turn, was named after a Soviet military official, Colonel Samarski. It is one of lanthanide metals which can be extracted from a number of minerals like monazites. This chemical element can also be produced artificially in labs. It is not toxic and has no biological importance. Samarium is often used in alloys with other metals like cobalt and iron to produce high power magnets used in electronic devices like headphones, etc. Samarium oxides have application in producing ceramics and glass.
