What is tellurium used for in daily life?

This passage showcased the use of the topic “What is tellurium used for in daily life” with related information about tellurium. It gave general information about tellurium, explained what tellurium is, what were the specific features of tellurium, how is tellurium formed, and of course, what is tellurium used for. Through this passage, you could have a general knowledge about tellurium, before getting to know what is tellurium used for.

Basic information about tellurium

Tellurium is one of the chemical elements, It has the symbol Te, and while atomic no. of it is 52 in the periodic table of elements. He belongs to group 16 in the periodic table, which would be a Chalcogen, the oxygen family. Tellurium is in period 5 of the periodic table, which is in the 5th row with 17 other elements. He is in the P-Block, the “principal”. Being at the right side of the periodic table, the p-block include elements from group 13 to 18, and the elements’ valence, or said outermost, electrons are all in the p orbital. Tellurium has 5 shells and on each shell in order there are 2, 8, 18, 18, and 6 electrons.

The appearance of tellurium is silver-grayish in crystalline form, and otherwise brownish-black in powder form. It will stay solid at STP, but it will melt at 449.51°C and boil at 988 °C. The density of Te is 6.24 g/cm3 in the solid state and 5.70 g/cm3 in the liquid state. The heat of fusion of Te is 17.49 kJ/mol.

Specific features of tellurium

Having known basic data about tellurium, let's get to know what kind of specific features tellurium possesses. Tellurium could be both crystalline and amorphous in the same condition. It is whiteish silver with a metallic shine when it is in crystalline form, and it would be in a trigonal and chiral shape when it is crystalline. In another form, amorphous, it would brownish black in a powder form.

Tellurium is a semiconductor. In some directions, in regards to the atomic alignment, Te’s electrical conductivity would increase, for example, when it is under light or exposed to photoconductivity, the conductivity increases.

When it comes to corrosiveness, tellurium has a specific feature. It is corrosive when it comes to copper, iron, or stainless steel.

The melting and boiling point of Te is at the highest point of the oxygen family elements.

Application for tellurium nowadays in daily life

Before getting into what is tellurium used for, we might need to gain some basic knowledge of some compounds with Te elements. There are a lot of compounds with the element Te, tellurium, for example, tellurium dioxide (TeSo3), Telluroxides, R Te3, telluraethers, Tellurium trioxide, Tellurium monoxide and so much more.

Common applications of Te

Tellurium monoxide is created in the heat of decomposing of TeSO3. This is applied in vacuums, TeSO3, is disproportionated into tellurium dioxide (TeO2) when heated.  Therefore Vacuums are one of the most common applications for Te.

While organotellurium compounds are used in research, as well as in semiconductors. Dimethyl telluride and other Te-related compounds are used to produce semiconductors as well. Tellurium suboxide is used as optical discs, the CDs in media, including rewritable compact discs and Blu-ray discs.

Besides compounds with Te element, tellurium is also the major material for a lot of products very commonly seen nowadays. Thin-film solar cells thermoelectric board is one of them, there are increasing demands as the sustainable energy application becomes more imminent. Tellurium is used for memory chips as well, which is a high demand as the data generation goes. Moreover, alloys, photovoltaics, and coins are all productions using directly Te as major materials.

Conclusion:

As far as this passage goes, on the topic of “what is tellurium used for”, by discussing what is tellurium used for in daily life, this passage showcased what Te is, what kind of chemical element Te belongs to, what features Te has, finally and most importantly, the application of this element tellurium, including Te and its compounds. It could be concluded that although Te is a very stable element, it is applied very commonly in daily life.
