Bismuth Telluride powder Bi2Te3



Bismuth Telluride is a grayish powder having the molecular form Bi2Te3. Bismuth informuride is a semiconductor substance with high electrical conductivity and low thermal conductivity. Although it is not dangerous, large quantities can cause death. The surface of this material will allow electrons and heat to flow on its surface at room temperatures, which could lead to an increase in chip operating speed.

Bismuth informuride is a compound of semiconductors of elements V, VI of the main list of periodic tables. A triangular crystal with a unit cell that is a homobic hexahedron. The lattice constant for this compound semiconductor is 1.0473nm. The density of the unit cell, 7.8587g/cm3. 585degC is the melting point. There are certain components of ionic bonds that can be combined by covalent bond.

Bismuth telluride has an indirect bandgap semiconductor of 0.145eV. It also features electron and hole mobilitys at 0.135 and 4.4.4×10-2m2/(V*s),, respectively. The thermoelectric quality coefficient is 1.6×10-3/K. If you are interested in Bismuth Telluride Powder, Bi2Te3 powder or bulk purchase, please send us an inquiry.

Bismuth Bi2Te3 powder features:

Bismuth-telluride is a semiconductor substance with high conductivity but low thermal conductivity. However, the danger of Bismuth Telluride can be fatal if there are large amounts of intake. But this material allows electrons to move at room temperature, without any energy. It will also increase chip performance and efficiency.

How is Bismuth Telluride Puffer Bi2Te3 Produced?

Bismuth Telluride is made by using three methods: the Bridgman and zone melting. Bi2Te3’s mineral form is bismuth-telluride. This is a moderately scarce material. You can find natural bismuth informurides in a variety of stoichiometric rates, as well compounds from the BiTe-S(Se) System, like Bi2Te2S.

Mixture of quartz powder and tellurium can be stored in a quartz tube in vacuum. (This is crucial because unsealed or leaky samples could explode in the furnace). The quartz tube will then be heated to 800°C in a muffle oven.

Application Bismuth Telluride Pulver Powder Bi2Te3

Bismuth Telluride (Bi2Te3), is an efficient thermoelectric material. Because of its many potential applications, Bismuth telluride (Bi2Te3) has attracted a lot of interest in the area energy harvesting, chip sensing, and material science.

Bismuth telluride, and its alloys, are used widely as thermoelectric refrigerator materials. These materials are ideal for creating thermoelectric generators if the heat source temperature remains moderate.

Bismuth Telluride is used as an insulator in topological applications for cooling or power generation.

Although topological insulators can’t be used as superconductors or for high-efficiency power lines because they are unable to carry large currents, this paradigm shift has opened the door to spintronics. That is, using electron spin to transmit information. In practical applications, however, it’s very simple to create and use bismuth-telluride. This material is easily made using the current mature semiconductor technology.

Storage condition of Bismuth powdered telluride Bi2Te3 powder:

Bi2Te3 Powder dispersion performance will be affected by dampness. Therefore, Bismuth informuride powder Bi2Te3 must be vacuum packed and kept dry in cool, dry rooms. Bismuth should not be exposed to direct air. Additionally, it is important to avoid stressing the Bi2Te3 Powder.

Packing & Shipping Bismuth telluride powder Bi2Te3 Powder:

Different types of packaging are available depending on the Bismuth powder Bi2Te3 quantity.

Packing of bismuth telluride powder B2Te3 in vacuum, 100g to 500g, or 1kg/bag for 25kg/barrel. Or as you request.

Shipping Bismuth telluride Powder B2Te3 powder: after payment receipt, shipping by sea or air.
