· NbSiPt

NbSiPt is a ternary intermetallic compound combining niobium, silicon, and platinum. This material belongs to the family of refractory metal silicides and represents a research-phase composition designed to achieve high-temperature structural stability and oxidation resistance by leveraging platinum's chemical nobility alongside niobium's refractory properties. The addition of silicon promotes the formation of protective oxide scales and enhances stiffness, making this alloy of particular interest for extreme-environment applications where conventional superalloys reach their temperature or oxidation limits.
