Tellurium is a brittle, silvery metalloid with semiconductor properties and uses in thermoelectric materials.
Properties of Tellurium | It forms chalcogenide compounds, has multiple oxidation states and combines with metals to form useful alloys.
Uses of Tellurium | Tellurium is recovered as a byproduct of copper refining and used in thermoelectric devices, solar cells and metallurgy.
Isotopes of Tellurium | Stable isotopes include Te 120 to Te 130; tellurium compounds can be toxic and handled with standard precautions.
