  • Bismuth telluride - Wikipedia

    Bismuth telluride (Bi 2 Te 3) is a gray powder that is a compound of bismuth and tellurium also known as bismuth(III) telluride. It is a semiconductor, which, when alloyed with antimony or selenium, is an efficient thermoelectric material for refrigeration or portable power generation. Bi 2 Te 3 is a topological insulator, and thus exhibits thickness-dependent physical properties.

    OccurrencePhysical CharacteristicsChemical CharacteristicsSignificance and UsesHealth EffectsIsotopes of TelluriumTellurium is not very common in the earth crust. Tellurium is present in about 1 part per billion in the Earth’s crust. The high atomic number and the formation of halides caused it to be lost in the space as a gas during the hot nebular formation of the planet. Like other metals such as copper, lead, silver or gold, it is often found in uncombined form but mostly present in mineral with gold. It is obtained as a by-product during the refinement of lead or copper. It is mostly found in the or...
  • TELLURIUM - Amethyst Galleries' Mineral Gallery

    Native tellurium is a rare mineral. When it does occur it is often found with gold and gold tellurides such as sylvanite and calaverite. The metal tellurium is mostly used in alloys with other metals. It is added to lead to improve its strength and durability. In steel and copper it makes the metals more workable.
