Tellurium

52

Description

Tellurium has two forms, crystalline and amorphous.

 

Crystalline tellurium is a silvery-white and brittle metal (or technically, a metalloid) with a typical metallic lustre. 

 

Amorphous tellurium is a black-brown powder prepared by precipitating it from tellurium or tellurous acid solution.

 

Tellurium is one of the rarest stable solid elements, generally found in the telluride form of more common metals. Most is obtained in trace amounts of porphyry copper deposits.
