Praseodymium bromide is an important raw material for the preparation of single rare earth metals by metal thermal reduction method, and can also be used for preparing organic glass coatings, etc. Prepare a unidirectional perspective glass. Including the inner layer and outer layer of glass.
Praseodymium fluoride (III) Applications: optical coating, fiber doping, laser crystals, single crystal raw materials, laser amplifiers, catalytic additives, etc.
Physical and chemical properties: light green crystal or powder, without water of crystallization. Insoluble in water, insoluble in hydrochloric acid, nitric acid, and sulfuric acid, but soluble in perchloric acid. It has hygroscopicity in the air and is relatively stable. Praseodymium fluoride is mainly used in laboratory reagents, fiber doping, laser materials, fluorescent materials, optical fiber, optical coating materials, electronic materials, etc.
Purpose: Used for the production of metal praseodymium and arc carbon rod chemicalbook additives, for vacuum deposition.
1. 50-100mg Pr6O11 was placed in a small platinum boat in a nickel reaction chamber, and dry N2 was introduced to expel air and water vapor. Then, ClF3 was slowly introduced and the reaction was carried out at room temperature. After the reaction is completed, N2 is introduced to remove unreacted ClF3. The above reaction was also carried out with high valence oxides Pr6O11 and PrO2, resulting in PrF3.
2. Dissolve praseodymium nitrate in 95% acetic acid and slowly add 40% hydrofluoric acid until the precipitation is complete.
