· JVASP-121857· Ta3Fe8Si

Ta₃Fe₈Si is an intermetallic compound combining tantalum, iron, and silicon, belonging to the family of refractory metal silicides and intermetallics. This material is primarily of research and development interest rather than established in high-volume production, with potential applications in high-temperature structural applications where the combined properties of tantalum's refractory character and iron's structural stability could be leveraged. The tantalum-iron-silicon system is investigated for aerospace and ultra-high-temperature environments where conventional superalloys reach their thermal limits.

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.
