Cerium(IV) fluoride hydrates a water insoluble Cerium source for use in oxygen-sensitive applications, such as metal production. Commercial applications for cerium include metallurgy, glass and glass polishing, ceramics, catalysts, and in phosphors. In steel manufacturing it is used to remove free oxygen and sulfur by forming stable oxysulfides and by tying up undesirable trace elements, such as lead and antimony.
