VSi2
metal· VSi2
VSi₂ is a vanadium disilicide intermetallic compound belonging to the transition-metal silicide family, characterized by a hexagonal crystal structure and moderate density. It is primarily of research and developmental interest for high-temperature structural applications, valued for its potential to combine refractory properties with improved oxidation resistance compared to pure vanadium. The material has been explored in aerospace and energy sectors where lightweight, high-temperature performance is critical, though it remains less commercially established than competing silicides like MoSi₂ or WSi₂.

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.
