· JVASP-39096· SiTc2W

SiTc₂W is a ternary intermetallic compound combining silicon, tungsten, and titanium carbide phases, belonging to the family of refractory metal silicides and carbides. This material is primarily of research interest for high-temperature structural applications where exceptional stiffness and thermal stability are critical, particularly in aerospace and power generation sectors where conventional superalloys reach their limits. Its tungsten and carbide content provides outstanding hardness and creep resistance, making it a candidate for next-generation turbine components and thermal protection systems, though practical adoption remains limited compared to established nickel-based superalloys and ceramic matrix composites.

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.
