· Hg0.72Cd0.28Te

Hg₀.₇₂Cd₀.₂₈Te is a cadmium mercury telluride (CMT) alloy semiconductor, a direct-bandgap material in the II-VI semiconductor family engineered for infrared detection. This composition is widely used in thermal imaging, night vision, and remote sensing systems where sensitivity to mid-wavelength infrared radiation (3–5 µm) is critical; it is preferred over alternatives like InSb or bolometric detectors because of its high quantum efficiency and tunable bandgap through compositional control. The alloy's maturity in production and proven performance in military, aerospace, and commercial thermal imaging make it a standard choice where cost and integration with existing cooled detector systems are acceptable tradeoffs.

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.
