· MgCo2S4

MgCo2S4 is a ternary metal sulfide compound combining magnesium, cobalt, and sulfur in a thiospinel or related crystal structure. This is an experimental/research material primarily investigated for electrochemical energy storage and catalytic applications, rather than a commercialized engineering material. The cobalt-sulfide family has gained attention for battery cathodes, supercapacitors, and hydrogen evolution catalysts, where the mixed-metal composition can offer improved electron conductivity and surface reactivity compared to binary sulfides.

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.
