Hf2Cr4Si5
metal· JVASP-119466· Hf2Cr4Si5
Hf2Cr4Si5 is a refractory intermetallic compound combining hafnium, chromium, and silicon—a material class designed for extreme-temperature structural applications. This composition belongs to the family of advanced ceramics and high-temperature metal silicides, primarily developed for aerospace and energy sectors where conventional superalloys reach their thermal limits. The hafnium-chromium-silicon system offers potential advantages in oxidation resistance and thermal stability, making it of particular interest to researchers developing next-generation turbine materials and thermal protection systems, though it remains largely in the research and development phase with limited commercial production.
