PrCr2Si2C
metal· JVASP-18077· PrCr2Si2C
PrCr₂Si₂C is an intermetallic compound combining praseodymium, chromium, silicon, and carbon—a member of the rare-earth transition metal silicide carbide family. This is a research-phase material studied for its potential in high-temperature structural applications where conventional superalloys or ceramics face limitations. The material combines metallic bonding character with intermetallic ordering, making it of interest for advanced aerospace and energy systems where damage tolerance and thermal stability are competing demands.
