Tellurium
Tellurium is a silvery-grey material. It is a poor conductor of heat and electricity, and, by some, is considered to be a metalloid rather than a true metal. Tellurium is slightly light sensitive, its electrical conductivity increasing slightly when light falls on it. Tellurium is very brittle, and when the molten element is slowly cooled, it forms rhombohedral crystals. Heated in a sealed tube with hydrogen, it forms brilliant prismatic crystals. When heated in air, tellurium burns with a blue flame.
Tellurium forms well-defined compounds with other metals, such compounds being known as tellurides. Bismuth telluride is a typical example of these compounds. Such compounds may be regarded as definite alloys of tellurium with other metals.
