(1) At higher temperatures, the metal does combine with many acids, the halogens, sulfur, selenium, and tellurium .(2) Elements such as lead, tellurium , beryllium, chromium, phosphorus, and manganese have little or no effect on the corrosion resistance of coppers and binary copper-zinc alloys.(3) Lead, tellurium and selenium are added to copper and its alloys to improve machinability.(4) Like selenium, tellurium is used in electronic devices.(5) Lead, selenium, tellurium and sulfur are added to copper alloys to improve machinability.(6) They separately synthesized rod-shaped nanometre scale crystal of two semi-conductors: cadmium selenide and cadmium telluride .(7) Newly developed handheld gamma-ray spectrometers based on cadmium zinc telluride detectors are currently being used to detect and identify radioisotopes in a variety of security and defense applications.(8) The boiling points decrease as the size of the electronegative atom decreases from hydrogen telluride to hydrogen sulfide.(9) The group is exploring cadmium telluride , cadmium sulfide, boron/phosphorous-doped silicon, and organic/polymeric materials and plans to assess more exotic photovoltaic materials in the future.(10) The most common minerals of gold are the tellurides , such as gold telluride, present in the mineral calavarite.
