· JVASP-155402· HfCu2HgS4

HfCu2HgS4 is a quaternary intermetallic compound combining hafnium, copper, mercury, and sulfur—a complex metal-based material that bridges metallic and chalcogenide chemistry. This is a research-phase compound with limited commercial production; it belongs to the family of ternary and quaternary metal sulfides that are investigated for potential applications in thermoelectrics, semiconductors, and solid-state devices where the combination of heavy elements (Hf, Hg) and transition metals (Cu) can produce unusual electronic and thermal 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.
