PrB₄ is a rare-earth boride ceramic compound combining praseodymium with boron in a refractory ceramic matrix. This material belongs to the rare-earth boride family, which is primarily explored in research and advanced materials development for extreme-temperature applications where conventional ceramics and metallic systems reach their limits. PrB₄ and related rare-earth borides are investigated for ultra-high-temperature structural applications, wear-resistant coatings, and specialized nuclear or aerospace environments, though commercial adoption remains limited compared to established ceramics like alumina or silicon carbide.
