· JVASP-15669· LaB2Ir2C

LaB2Ir2C is a ternary ceramic compound combining lanthanum boride, iridium, and carbon phases, representing an experimental high-entropy ceramic system. This material family is primarily of research interest for extreme-temperature applications where conventional ceramics fail, with potential use in aerospace thermal protection and high-temperature structural components due to the refractory nature of boride-carbide systems. The iridium addition provides oxidation resistance and thermal stability characteristics not typically found in simpler boride or carbide ceramics, though practical engineering applications remain largely in development phase.
