· Hg0.77Cd0.23Te

Hg0.77Cd0.23Te is a mercury cadmium telluride (MCT) alloy, a narrow-bandgap semiconductor compound commonly engineered for infrared detection applications. This material is widely used in thermal imaging systems, military surveillance, and scientific instrumentation because its bandgap can be precisely tuned by adjusting the mercury-to-cadmium ratio, making it exceptionally sensitive to mid- and long-wavelength infrared radiation where competing detectors are less effective. MCT remains the industry standard for high-performance thermal imaging despite challenges in manufacturing uniformity and the need for cryogenic cooling in many applications.

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.
