Usage

Uses

Praseodymium trihydroxide used to colour glasses ,enamels and pigments. Much research is being done on its optical properties for use in amplification of telecommunication systems. It can be used to create high-power magnets notable for their strength and durability. It is present in the rare earth mixture whose Fluoride forms the core of carbon arc lights which are used in the motion picture industry for studio lighting and projector lights.
