· Ta10 Si6

Ta10Si6 is a tantalum-silicon intermetallic compound belonging to the refractory metal silicide family, combining tantalum's high melting point and density with silicon's light weight and oxidation resistance. This material is primarily of research and development interest for ultra-high-temperature structural applications where conventional superalloys reach their limits, such as aerospace propulsion systems and thermal protection structures. Ta10Si6 and related tantalum silicides are investigated as candidates for hypersonic vehicle components and next-generation rocket engine materials, though they remain largely experimental; their appeal lies in the potential to operate at temperatures where nickel-based superalloys degrade while maintaining lower density than pure refractory metals.

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.
