· Hg0.1Cd0.9Se

Hg₀.₁Cd₀.₉Se is a mercury-cadmium-selenide mixed alloy belonging to the II-VI semiconductor family, engineered to occupy a specific position in the infrared bandgap spectrum between cadmium selenide and mercury selenide end members. This narrow-bandgap material is primarily used in infrared detection and thermal imaging applications where sensitivity in the mid-to-long wavelength infrared (MWIR/LWIR) regions is required; it competes with lead-tin telluride and antimony-based III-V compounds for cooled detector arrays and offers advantages in wavelength selectivity and fabrication compatibility for focal plane arrays. The material is generally classified as research-grade or niche-production due to mercury's toxicity and manufacturing complexity, though it remains important in military, space, and scientific instrumentation where performance justifies the handling requirements.

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.
