Praseodymium fluoride is a light green crystal or powder, which does not contain crystal water, insoluble in water, difficult to dissolve in hydrochloric acid, nitric acid and sulfuric acid, but can dissolve in perchloric acid. The preparation method is to add hydrofluoric acid to praseodymium salt solution, or to prepare hydrated praseodymium fluoride from praseodymium hydroxide and hydrofluoric acid, and then to get praseodymium fluoride by vacuum heating.
【Application】
1. It is suitable for ceramics manufacturing.
2. It is resistant to many reactive molten metals such as titanium or uranium.
3. For producing of multilayer ceramic capacitors, Yttrium oxide is also employed as a dopant to reduce the Curie temperature of the barium titanate substrate due to its special properties.
【Specification】
1. Chemical properties: TREO>98.5%,PrF3/TREO>99.999%
2. Color:green

【Product features】
Yttrium oxide because of its properties may also be used as a laminated insulator. Y2O3 is the most thermodynamically stable compound in the oxide group. It is resistant to many reactive molten metals such as titanium or uranium. In its industrial application as a pure ceramic, yttrium oxide is still a relatively new material.
