· JVASP-15831· CrS2

Chromium disulfide (CrS₂) is a transition metal chalcogenide compound combining chromium with sulfur in a 1:2 stoichiometric ratio. While not widely established in commercial applications, CrS₂ belongs to a family of metal sulfides being explored in advanced materials research for its potential in energy storage, catalysis, and semiconductor applications. Its layered crystal structure and mixed-valence chemistry make it a candidate material for next-generation technologies, though production methods and performance optimization remain active areas of investigation.
