· JVASP-12406· ErSiRh

ErSiRh is a ternary intermetallic ceramic compound combining erbium, silicon, and rhodium. This is a research-phase material belonging to the rare-earth silicide family, where the rhodium addition modifies the microstructure and mechanical response compared to binary erbium silicides. While not yet in widespread commercial production, materials in this class are investigated for high-temperature structural applications where thermal stability and oxidation resistance are critical, particularly in aerospace and energy sectors where conventional refractory ceramics may be insufficient.
