· CoSb

CoSb is an intermetallic compound composed of cobalt and antimony, belonging to the family of binary metal antimonides. This material is primarily of research and emerging technology interest rather than a mainstream industrial commodity. CoSb and related antimonide compounds are investigated for thermoelectric applications, where they can convert thermal gradients into electrical energy, and for their potential in semiconductor and magnetoelectronic devices where the intermetallic structure offers tunable electronic properties.

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.
