· Ni4 Sb4 S4

Ni₄Sb₄S₄ is a quaternary chalcogenide semiconductor compound combining nickel, antimony, and sulfur in a layered crystal structure. This material is primarily of research and developmental interest rather than established industrial production, studied for its potential in thermoelectric applications, optoelectronics, and solid-state device physics where the interplay of multiple metallic and chalcogenide components enables tunable electronic and thermal properties.

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.
