Praseodymium fluoride (PrF₃) is an inorganic ceramic compound belonging to the rare-earth fluoride family, characterized by its ionic crystal structure and high chemical stability. It is primarily used in specialized optics, laser systems, and advanced ceramics research, where its fluoride composition provides excellent transparency in the infrared spectrum and resistance to thermal shock. As a rare-earth material, PrF₃ is notable for applications requiring high-temperature stability and specific luminescent or optical properties that distinguish it from common oxide ceramics, though it remains largely confined to research, aerospace, and high-performance photonics rather than commodity applications.
