· JVASP-123669· HgSe2

HgSe2 is a mercury selenide ceramic compound belonging to the chalcogenide family of semiconductors. It is primarily investigated in research contexts for infrared detection and optoelectronic applications, where its narrow bandgap and high refractive index make it suitable for thermal imaging systems and infrared sensors. While not widely deployed in mainstream industrial production due to mercury's toxicity and handling constraints, this material represents an important reference compound in the semiconductor research community for understanding II-VI semiconductor behavior and for specialized defense and scientific instrumentation where performance justifies material management complexity.

Regulatory Screening

Environmental

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.
