· JVASP-30551· Cr2S5

Cr2S5 is a chromium sulfide compound that belongs to the transition metal sulfide family, characterized by mixed-valence chromium bonded with sulfur. While not widely deployed in mainstream industrial applications, chromium sulfides are of significant research interest as solid lubricants, catalytic materials, and potential components in energy storage systems, where their layered crystal structure and chemical stability offer advantages over conventional alternatives in high-temperature or corrosive 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.
