Cadmium telluride, with the symbol CdTe, atomic weight is 250, is the black cubic crystal, toxic.

Its melting point is 1041℃, the density is 6.20g/cm³, not soluble in the water and acid but can be resolved with nitric acid. It can be oxidized by the air when humid. It's formed by the Tellurium element and Cadmium element mix melted and sublimated under the hydrogen flow. Or It can be get from Tellurite or tellurite hotted with reduction reaction under hydrogen flow, or get by acidized effect by the cadmium acetate reacted from acetic acid and sodium carbide, the sediment is maroon and black when dry.

7N 99.99999% purity Cadmium tellurideis used for semiconductor material of spectral analysis and infrared detector, x-rxy generator and Nuclear radiation detector.
