About Bismuth Telluride Powder Bi2Te3 Powder:
Bismuth telluride is a gray powder with the molecular formula Bi2Te3. Bismuth telluride is a semiconductor material with good electrical conductivity, but poor thermal conductivity. Although the danger of bismuth telluride is low, it can be fatal if ingested in large amounts. However, this material can allow electrons to move on its surface without energy consumption at room temperature, which will bring a leap in the operating speed of the chip, even It can greatly improve the operating speed and work efficiency of the computer chip.
Bismuth telluride is a compound semiconductor of elements V and VI of the main group of the periodic table. Triangular crystal, the unit cell is a rhombic hexahedron, the lattice constant is 1.0473nm, and the density is 7.8587g/cm3. The melting point is 585°C. Combined by covalent bonds, there are certain ionic bond components.
Bismuth telluride is an indirect bandgap semiconductor with a bandgap of 0.145eV at room temperature, electron and hole mobility of 0.135 and 4.4×10-2m2/(V·s), respectively, and a thermoelectric quality coefficient of 1.6×10-3/K.

Features of Bismuth telluride Bi2Te3 powder:
Bismuth telluride is a semiconductor material, with good conductivity, but poor thermal conductivity. Although the risk of bismuth telluride is low, if a large number of intake is also a fatal danger but this material can allow electrons at room temperature without energy in the surface of its movement, which will bring the chip speed of operation, even Can greatly improve the computer chip running speed and efficiency.
Specification of Bismuth telluride powder Bi2Te3 powder:
Note: according to user requirements can provide different size products.
How is Bismuth Telluride Powder Bi2Te3 Powder produced?
Bismuth telluride is prepared by the Bridgman method, zone melting method, and Czochralski method. The mineral form of Bi2Te3 is bismuth telluride, which is moderately rare. There are many natural bismuth tellurides with different stoichiometric ratios, as well as compounds of the Bi-Te-S-(Se) system, such as Bi2Te2S.
The mixed powder of quartz and tellurium metal can be sealed in a quartz tube under vacuum (this is critical because unsealed or leaked samples may explode in the furnace), and then heated to 800°C in a muffle furnace To achieve the preparation of bismuth telluride.
Application of Bismuth Telluride Powder Bi2Te3 Powder:
Bismuth telluride (Bi2Te3) is basically an effective thermoelectric material. Nowadays, due to its potential applications, it has aroused great interest in another area of energy harvesting, chip cooling, chip sensing and material science.
Bismuth telluride and its alloys are widely used as thermoelectric refrigeration materials. When the heat source temperature is moderate, they are also the best materials for thermoelectric generators.
Bismuth telluride is commonly used for power generation or cooling applications, as a topological insulator.
Topological insulators are not conventional superconductors, nor can they be used for ultra-efficient power lines, because they can only carry very small currents, but they paved the way for the paradigm shift in microchip development, which will lead to new applications of spintronics, That is, the use of electron spin to carry information. Moreover, bismuth telluride is very easy to produce and use in practical applications. This three-dimensional material can be manufactured by the existing mature semiconductor technology, and it is also easy to dope so that its performance can be tuned quite easily.
Storage Condition of Bismuth telluride powder Bi2Te3 powder:
The damp reunion will affect Bi2Te3 powder dispersion performance and using effects, therefore, Bismuth telluride powder Bi2Te3 powder should be sealed in vacuum packing and stored in cool and dry room, Bismuth telluride can not be exposure to air. In addition, the Bi2Te3 powder should be avoided under stress.
Packing & Shipping of Bismuth telluride powder Bi2Te3 powder:
