Top 14 interesting facts about Tellurium

  • Tellurium was discovered in 1782 by Franz Muller von Reichenstein. Tellurium's name derives from the Greek words "tellus" which mean "Goddess of the Earth".
  • Tellurium's melting point is at 449.5 C (722.65 K, 841.1 F) and its boiling point is at 989.8 C (1262.95 K, 1813.64 F).
  • Tellurium is a brittle silver-white metalloid.
  • Tellurium is chemically similar to selenium and sulfur.
  • Tellurium is a rare metal on Earth but more common in the universe.
  • Tellurium was first discovered in Romania.
  • Tellurium is obtained as a by product of cooper and lead production.
  • Tellurium is mainly produced in the USA, Japan, Canada, and Peru.
  • Tellurium is mainly used in metallurgy in iron, cooper, and lead alloys.
  • Tellurium's other applications are in: electronic industry, ceramic industry, and several other small applications.
  • Tellurium has eight naturally occurring isotopes: five are stable (122-Te, 123-Te, 124-Te, 125-Te and 126-Te) and 3 are radioactive (120-Te, 128-Te, and 130-Te).
  • Tellurium's stable isotopes make up only 33% of the whole naturally occurring tellurium on Earth.
  • Tellurium is found in nature in elemental form but more often as a telluride of gold or as a telluride of other more common elements such as telluride of nickel.
  • Tellurium has no biological role in living organisms.
