· JVASP-140458· Cd4HgSe5

Cd₄HgSe₅ is a ternary semiconductor ceramic compound combining cadmium, mercury, and selenium—a member of the II-VI semiconductor family used in specialized optoelectronic and photonic applications. This material is primarily of research and development interest for infrared detection, photovoltaic conversion, and radiation sensing due to the bandgap properties afforded by its multi-element composition. While less commonly deployed in high-volume production than simpler binary semiconductors, ternary cadmium-mercury-selenium compounds are investigated for applications requiring tunable optical response or enhanced sensitivity in specific wavelength ranges.

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.
