· Zr2Si

Zr2Si is an intermetallic compound combining zirconium and silicon, belonging to the refractory metal silicide family. This material is primarily of research and development interest for high-temperature structural applications where thermal stability and mechanical performance at elevated temperatures are critical. Zr2Si and related zirconium silicides are explored for aerospace propulsion systems, nuclear reactor components, and advanced thermal barrier coatings, where their ceramic-like rigidity combined with metallic conductivity offers advantages over traditional superalloys in extreme environments.

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.
