· JVASP-100639· Ta2CrSi6

Ta2CrSi6 is an intermetallic compound combining tantalum, chromium, and silicon—a refractory metal silicide belonging to the family of high-temperature structural materials. This is largely a research-phase material studied for extreme-environment applications where traditional superalloys reach their thermal limits; it combines the oxidation resistance and high melting point of tantalum-based systems with the lightweight potential of silicide chemistry. Engineers consider this material class when designing components for hypersonic vehicles, advanced gas turbines, or space propulsion systems where sustained performance above 1000°C and resistance to thermal cycling are critical, though practical commercial deployment remains limited compared to established nickel superalloys or molybdenum disilicides.

Export Control

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
