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.

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.
The common association of gold and bismuth tellurides means that the most occurrences of bismuth tellurides in British Columbia have been investigated for their gold content. This is common world-wide and has led to the recognition of bismuth tellurides in a
Bismuth telluride heat pump. This is a small bismuth telluride thermoelectric heat pump. Apply a DC voltage and one side gets cold while the other side gets hot. If you attach a good heat sink and fan to the hot side, you can pump heat out of something, cooling it down. This particular device was deployed inside a USB-powered mini-fridge ...

Tellurium is a relatively rare element, in the same chemical family as oxygen, sulfur, selenium, and polonium: oxygen and sulfur are nonmetals, polonium is a metal, and selenium and tellurium are semiconductors (i.e., their electrical properties are between those of a metal and an insulator).
Tellurium is used as a basic ingredient in blasting caps, and is added to cast iron for chill control. Tellurium is used in ceramics. Bismuth telluride has been used in thermoelectric devices. Tellurium is available as metal and compounds with purities from 99% to 99.999% (ACS grade to ultra-high purity).
When alloyed with a number of other elements, such as cadmium, mercury, bismuth and zinc, tellurium forms a telluride compound that enhances a material’s ability to conduct electricity; this ...

Tellurium has two forms, crystalline and amorphous. Crystalline tellurium is a silvery-white and brittle metal (or technically a metalloid) with a typical metallic luster. Amorphous tellurium is a black-brown powder prepared by precipitating it from tellurium or tellurous acid solution.

Could you inform to me about the specific heat of Bi2Te3 and Sb2Te3 the range from 300K to 500K. Thank you. Sincerely Yours, Kim
Bismuth Telluride is a narrow gap layered semiconductor with high thermal conductivity. Recent research has confirmed that bismuth telluride may significantly increase the speed of microchips and be the basis for the emerging next generation technology know as "Spintronics".
Native Tellurium is very uncommon, and is only occasionally used as an ore of tellurium where other tellurium minerals occur. Nevertheless, the uses of the element tellurium are briefly mentioned: Tellurium is used industrially for thermoelectric apparatuses and in the process of creating rubber.

Tellurium was discovered in 1783 by Franz Joseph Müller von Reichenstein at Sibiu, Romania. He became intrigued by ore from a mine near Zalatna which had a metallic sheen and which he suspected was native antimony or bismuth. (It was actually gold telluride, AuTe 2.) Preliminary investigation showed neither antimony nor bismuth to be present.
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.
