Tellurium | Chemical elements

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).

Top 12 interesting facts about Tellurium

  1. Tellurium is a brittle silver-white metalloid.
  2. Tellurium is chemically similar to selenium and sulfur.
  3. Tellurium is a rare metal on Earth but more common in the universe.
  4. Tellurium was first discovered in Romania.
  5. Tellurium is obtained as a by product of cooper and lead production.
  6. Tellurium is mainly produced in the USA, Japan, Canada, and Peru.
  7. Tellurium is mainly used in metallurgy in iron, cooper, and lead alloys.
  8. Tellurium’s other applications are in: electronic industry, ceramic industry, and several other small applications.
  9. 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).
  10. Tellurium’s stable isotopes make up only 33% of the whole naturally occurring tellurium on Earth.
  11. 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.
  12. Tellurium has no biological role in living organisms.
