· JVASP-15885· ThB2Ir3

ThB2Ir3 is an intermetallic ceramic compound combining thorium boride with iridium, belonging to the family of refractory boride ceramics. This material is primarily of research and development interest rather than established commercial production, with potential applications in extreme high-temperature environments where thermal stability and chemical resistance are critical. The addition of iridium to thorium boride systems is explored to enhance fracture toughness and oxidation resistance compared to simpler boride ceramics, making it a candidate for next-generation aerospace and nuclear thermal protection applications.
