· JVASP-133434· Nb3Cr8Si

Nb3Cr8Si is an intermetallic compound belonging to the niobium-chromium-silicon family, characterized by a complex crystal structure that combines the refractory properties of niobium with the oxidation resistance contributions of chromium and silicon. This material is primarily studied in research and development contexts for high-temperature structural applications, where its combination of high-temperature stability and relatively low density make it a candidate for aerospace and power generation environments that demand exceptional thermal performance. Its appeal lies in the potential to extend operating temperatures beyond conventional nickel-based superalloys while maintaining workability advantages over brittle ceramic competitors.

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.
