· JVASP-75880· Hg2AsSe

Hg₂AsSe is a mercury-based mixed-halide ceramic compound belonging to the class of heavy-metal chalcogenides and pnictides. This is an experimental/research material primarily investigated for its potential in infrared (IR) optics and nonlinear optical applications, where the combination of mercury, arsenic, and selenium creates a wide transparency window in the mid- to long-wavelength IR spectrum. The material's notable advantage over alternatives like ZnSe or CdTe is extended transmission into longer IR wavelengths, making it valuable for thermal imaging, spectroscopy, and laser systems, though its development remains largely in the research phase with limited commercial availability.

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.
