Bismuth Telluride powder Bi2Te3 Powder :
Bismuth Telluride is a grayish powder having the molecular structure Bi2Te3. Bismuth informuride is a semiconductor substance with high electrical conductivity and low thermal conductivity. Bismuth Telluride has a very low danger, however it is possible to be fatal if taken in large quantities. This material is able to allow electrons on its surface to move at room temperatures without energy consumption, which can lead to a jump in operating speed.
Bismuth informuride is a compound of semiconductors of elements V, VI of the main list of the periodic table. 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 also covalent and ionic bonds.
Bismuth telluride has an indirect bandgap semiconductor of 0.145eV. The bandgap is at room temperature. There are electron and hole mobilitys (V*s) of 0.135 and 4.4.4x10-2m2/(V*s) of respectively. Also, the thermoelectric quality coefficient is 1.6x10-3/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. Although it is not a very dangerous substance, it can cause serious injury if there are too many people inhaling.

How Bismuth Telluride Puffer Bi2Te3 is it made?
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 of the BiTe-S(Se), 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 of 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 not able 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 and 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:
There are many packing options 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: could ship out by sea or air as soon after receipt of payment.
