High Purity Bismuth Telluride Powder Bi2Te3 Cas 1304-82-1,99.99% |

Bismuth Telluride Powder Bi2Te3 Powder :
Bismuth telluride, also known as gray powder or Bi2Te3, is a molecular compound with the formula Bi2Te3. Bismuth telluride, a semiconductor material, has good electrical conductivity but poor thermal resistance. It is not harmful to ingest small amounts of bismuth, but large doses can cause death. The material is able to allow electrons on its surface to move at room temperatures without consuming energy, which can lead a significant increase in the speed.
Bismuth telluride, a compound semiconductor composed of elements V and 6 of the main periodic table group is also known as bismuth oxide. The crystal structure is triangular, with a unit cell that is a rhombic hexagon. The melting temperature is 585degC. Covalent bonds and certain ionic components are combined.
Bismuth telluride has a thermal quality coefficient of 1.66×10-3K and is an indirect bandgap semiconductor with a 0.145eV bandgap. It also has electron and hole mobility values of 0.135m2/(V*s) and 4.42×10-2m2/ (V*s).

What is the production process of Bismuth Telluride (Bi2Te3) Powder ?
Bismuth Telluride can be prepared using the Bridgman Method, Zone Melting Method, or Czochralski Method. The mineral form is Bismuth telluride. It is a moderately rare mineral. Bismuth tellurides are found in a variety of natural forms with different stoichiometric values. They also occur as compounds from the Bi-Te – S-(Se), such as Bi2Te2S.
To make bismuth-telluride, you can heat the mixture of tellurium and quartz powder in a muffle oven to 800degC.

Application Bismuth Telluride (Bi2Te3) Powder Powder ?
Bismuth telluride is a thermoelectric compound. Due to its potential, it has sparked interest in other areas of energy harvesting.
Bismuth telluride alloys and their compounds are commonly used as thermoelectric cooling materials. These materials are ideal for thermoelectric generators when the heat source is moderate.
Bismuth Telluride is used as a topological insulate for cooling or power generation applications.
Topological insulators, however, are not superconductors and cannot be used to create ultra-efficient electrical lines because they carry only very small currents. But they paved a way for the new paradigm in microchip technology, leading to new spintronics applications, which is the use electron spins to convey information. Bismuth telluride, which is used for practical applications, is also very easy to manufacture. This material is easy to produce using the mature semiconductor technology. It can also be easily doped, so that it can be tuned.

Storage condition of Bismuth Telluride powder (Bi2Te3 Powder):
Bismuth telluride should not be exposed to air. Bi2Te3 Powder should not be exposed to stress.
