· JVASP-142305· MoSI

MoSI is an intermetallic compound combining molybdenum and silicon, belonging to the refractory metal silicide family. It is primarily of research and developmental interest for high-temperature structural applications where exceptional thermal stability and oxidation resistance are required. The material shows promise in aerospace and power generation sectors where conventional superalloys reach thermal limits, though industrial adoption remains limited compared to established alternatives.
