· JVASP-11428· Y3Si3Rh

Y3Si3Rh is an intermetallic ceramic compound combining yttrium, silicon, and rhodium in a structured lattice. This is a research-phase material within the rare-earth silicide family, studied for potential applications requiring combined thermal stability, oxidation resistance, and high-temperature mechanical performance. The incorporation of rhodium—a precious refractory metal—suggests investigation into ultra-high-temperature structural applications where conventional ceramics or superalloys reach their limits.
