Tellurium is present in the Earth's crust only in about 0.001 parts per million. Tellurium minerals include calaverite, sylvanite and tellurite. It is also found uncombined in nature, but only very rarely. It is obtained commercially from the anode muds produced during the electrolytic refining of copper. These contain up to about 8% tellurium.

F. J. Muller von Reichenstein, a Romanian mining official, discovered the silver-white metalloid tellurium in 1782. While being found free in nature, tellurium is most frequently found as the telluride of gold (calaverite) and several other ores. In crystalline form, tellurium has a silvery white color and, in its pure state, the metalloid ...

Tellurium dioxide is formed by heating tellurium in air, causing it to burn with a blue flame.[18] Tellurium trioxide, β-TeO3, is obtained by thermal decomposition of Te(OH)6. The other two forms of trioxide reported in the literature, the α- and γ- forms, were found not to be true oxides of tellurium in the +6 oxidation state, but a mixture ...
