· JVASP-40537· TaRu3

TaRu3 is an intermetallic ceramic compound combining tantalum and ruthenium in a 1:3 ratio, representing a refractory metal system designed for extreme-temperature and corrosive environments. This material belongs to the family of high-entropy and transition-metal ceramics being investigated for aerospace and chemical processing applications where conventional superalloys reach their thermal or chemical limits. The tantalum-ruthenium system is notable for its potential high melting point and oxidation resistance, though TaRu3 itself remains primarily a research-phase compound rather than an established commercial material.
