Tellurium has been used to
vulcanise rubber, to tint glass and ceramics
, in solar cells, in rewritable CDs and DVDs and as a catalyst in oil refining. It can be doped with silver, gold, copper or tin in semiconductor applications.
What is an interesting fact about tellurium?
Interesting Tellurium Facts:
Tellurium is one of the rarest elements on Earth
, but is abundant in space. It is found on Earth with nearly the same abundance as platinum. Tellurium is believed to have been depleted from the crust during the formation of the planet due to its volatile reaction with hydrogen.

Where is tellurium commonly found in nature?
Tellurium is found free in nature, but is most often found in
the ores sylvanite (AgAuTe
4
), calaverite (AuTe
2
) and krennerite (AuTe
2
)
. Today, most tellurium is obtained as a byproduct of mining and refining copper. Tellurium is a semiconductor and is frequently doped with copper, tin, gold or silver.
Is tellurium used in medicine?
Tellurium found historical applications in the
treatment of microbial infections
prior to the discovery of antibiotics. Early documentation in 1926 reports its use in the treatment of syphilis and leprosy (De Meio and Henriques 1947).

What does tellurium stand for?
Tellurium is a chemical element with the symbol
Te
and atomic number 52. It is a brittle, mildly toxic, rare, silver-white metalloid. Tellurium is chemically related to selenium and sulfur, all three of which are chalcogens. It is occasionally found in native form as elemental crystals.
Is tellurium a rare Earth?
Tellurium is one of the least common elements on Earth. Most rocks contain an average of about 3 parts per billion tellurium, making
it rarer than the rare earth elements
and eight times less abundant than gold.
Can you buy Tellurium?
It is possible to obtain Tellurium from
Fortuna bounties
as one of the rewards from the different reward tables available. Using the Spare Parts mod that equips into sentinels, players may obtain Tellurium when the effects of the mod occur.

What are the biological effects of tellurium?
Moreover, tellurium, at low concentrations,
induces both acute and chronic toxicity in a variety of organisms
. Nevertheless, several studies have shown that trace amounts of tellurium are present in body fluids, such as blood and urine (Goulle’ et al. 2005).
Does tellurium dissolve in water?
Tellurium is a silvery-white semi-metallic element that is crystalline and brittle. It remains stable in water or hydrochloric acid, but
will dissolve in nitric acid
.
