· JVASP-49211· K6CoS4

K6CoS4 is an intermetallic sulfide compound containing potassium, cobalt, and sulfur, representing a rare-earth or specialty metal chalcogenide in the research domain. This material belongs to an emerging class of multinary metal sulfides being investigated for energy storage and catalytic applications, particularly in battery electrodes and electrocatalysis for hydrogen evolution. While not yet established in mainstream industrial production, materials in this family are notable for their potential to offer tunable electronic properties and cost advantages over precious-metal-based catalysts.

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.
