ceramic

· JVASP-37019· TlCdTe2

TlCdTe2 is a ternary compound ceramic composed of thallium, cadmium, and tellurium, belonging to the chalcogenide family of semiconductors. This material is primarily of research interest for infrared detection and optoelectronic applications, where its wide bandgap and thermal properties make it a candidate for specialized sensing systems; however, it remains largely experimental rather than widely commercialized, and toxicity concerns associated with thallium and cadmium limit its practical deployment compared to more established alternatives like mercury–cadmium–telluride (MCT) or lead–based compounds.
