B4Ir3
ceramic· B4Ir3
B4Ir3 is an intermetallic ceramic compound combining boron and iridium, belonging to the family of refractory metal borides. This material is primarily of research and developmental interest rather than established commercial production, pursued for extreme-temperature applications where conventional ceramics and superalloys reach their limits. The iridium-boron system offers potential for applications demanding exceptional oxidation resistance, hardness, and thermal stability at temperatures beyond 1500°C, though challenges in processing, brittleness, and cost have limited widespread industrial adoption compared to established alternatives like alumina or zirconia ceramics.
