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.
