Praseodymium hexaboride (PrB₆) is an advanced ceramic compound belonging to the rare-earth hexaboride family, characterized by a cubic crystal structure and strong ionic-covalent bonding. This material is primarily of research and specialized industrial interest, valued for its high hardness, thermal stability, and electrical properties that make it attractive for high-temperature and wear-resistant applications. Compared to traditional boride ceramics, rare-earth hexaborides offer enhanced performance in extreme environments and are being explored as alternatives to tungsten-based materials in specific aerospace and defense contexts.
