· JVASP-8385· YCoF5

YCoF5 is an yttrium-cobalt fluoride intermetallic compound, a specialized ceramic or intermetallic material combining rare-earth and transition-metal elements. This is primarily a research-phase material studied for its potential in high-temperature applications and functional material systems where fluoride chemistry offers thermal stability or unique electronic properties not available in conventional oxide ceramics.
