About Dysprosium

This chemical element is quite rare and, just like other lanthanides, it is a soft dark silvery color metal. The name of this element is derived from the Greek expression meaning difficult to get. Dysprosium is not toxic and is not of essence to the living organisms. It is reactive and forms quite a large number of compounds with such elements as chlorine, sulfur, iodine, bromine, oxygen, and others. The applications of these compounds include producing magnets and parts for electronic devices, for lamps, wind turbines, vehicles, and other industrial goods.
