MoIr3
metal· MoIr3
MoIr3 is an intermetallic compound combining molybdenum and iridium in a 1:3 atomic ratio, belonging to the family of refractory metal intermetallics. This material is primarily of research and development interest rather than established in broad industrial production, with potential applications in extreme-environment applications where very high melting points and chemical stability are required. Its notable characteristics stem from iridium's exceptional hardness and corrosion resistance combined with molybdenum's strength, making it a candidate for specialized aerospace, chemical processing, or high-temperature catalytic applications where conventional superalloys reach their limits.
