Leoq de Boisbaudran discovered Dysprosium in 1886 , but it was not isolated unitl the ion-exchange separation was developed. Dysprosium is relatively stable at room temperature and is quickly attacked and will dissolve. The metal is soft enough to be cut with a knife and if the metal was to machined it would cause no spark it was not overheated. The only use for Dysprosium is a oxide-nickel cement used in cooling nuclear reactor control rods.
