Tellurium Single Crystal 52Te127.60
Tellurium was discovered in 1783 by Baron Franz Joseph Müller von Reichenstein at Sibiu, Romania.
[Latin: tellus = earth] French: tellureGerman: tellur
Italian: tellurio
Spanish: teluro
Description: Tellurium is a silvery-white, metallic-looking in bulk, but is usually obtained as a dark grey powder. It is a semi-metal. Tellurium burns in air or oxygen, is unaffected by water or HCl, but dissolves in HNO3. It is used in alloys to improve machinability, in electronics, and in catalysts.
