Due to its strongly magnetizing, phosphorescent properties, terbium offers a whole range of possible applications. In combination with zirconium oxide, terbium is of great importance in fuel cell technology. Alongside dysprosium, neodymium and europium, terbium is used to increase the coercive field strength. It is also used in phosphors to create green color effects. In dentistry, it is used in the production of all-ceramic systems.
