· Cd0.3Hg0.7Te1

Cd₀.₃Hg₀.₇Te is a cadmium-mercury telluride ternary semiconductor alloy, part of the II-VI compound semiconductor family widely used in infrared detection and imaging. This material is the primary detector medium in long-wavelength infrared (LWIR) applications, where its tunable bandgap—controlled by cadmium-to-mercury ratio—enables detection across the 8–14 μm atmospheric window and beyond. Engineers select this alloy over alternatives like InSb or bolometers because it offers superior sensitivity, quantum efficiency, and room-temperature or modestly cooled operation in thermal imaging, military surveillance, medical thermography, and scientific spectroscopy; however, cadmium and mercury toxicity require careful handling and specialized manufacturing.

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.
