BRIEF DESCRIPTION
Praseodymium fluoride, light green crystals or powder, does not contain crystal water. It is insoluble in water, difficult to dissolve in hydrochloric acid, nitric acid and sulfuric acid, but soluble in perchloric acid. It is hygroscopic in the air and relatively stable. Praseodymium fluoride is mainly used in laboratory reagents, optical fiber doping, laser materials, transluminescent materials, optical fibers, optical coating materials, electronic materials, etc.
