Tellurium


Tellurium was discovered in 1782, by Franz Müller von Reichenstein after several studies of a blueish gold ore, extracted in a mine in Transilvania. Müller accomplished a careful chemical analysis of this ore, and reported residues of a metal very similar to antimony. However, Müller was not able to identify this metal. It took over a year to consider this hypothesis. The metal was isolated, in 1798, by Klaproth that was interested in the work of Müller, as he was decided to check the existence of a new element. This scientist suggested its actual name , that derives of the Latin "tellus", that means earth.
