The main area of telluriumconsumption is alloys and steel production; tellurium improves corrosion resistance of lead and facilitates mechanical processing of copper and stainless steel. Semiconductor properties of tellurium find their application in manufacturing of photo cells, infrared detectors, thermoelectric generators and refrigeration thermocouples. Tellurium is used for the production of thermocouples for measuring low temperatures. Tellurium is used to give the glass a brown tint. In rubber industry tellurium is used for rubber vulcanizing, increasing its resistance to heat and abrasion.
