· JVASP-35393· Co2NiSe4

Co₂NiSe₄ is a quaternary metal selenide compound combining cobalt, nickel, and selenium in a fixed stoichiometric ratio, belonging to the chalcogenide family of materials. This is primarily a research-phase compound studied for its potential in thermoelectric and optoelectronic applications, where the mixed-metal selenide structure offers tunable electronic properties and moderate mechanical stiffness. The Co-Ni-Se system is of particular interest in materials research for energy conversion devices and solid-state electronics where layered or structured selenides can provide improved performance over single-element alternatives.

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.
