Bismuth Telluride is a grayish powder having the molecular form Bi2Te3. Bismuth telluride can be used as a semiconductor material, with high electrical conductivity and low thermal conductivity. Particle Size: -80mesh and -100mesh Purity: 99.99% Bismuth Telluride Powder Bi2Te3 powder: 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. 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 VI and V from the main group on the periodic table. A triangular crystal with a unit cell that is a rhombic hexagon, its lattice constant at 1.0473nm is and density of 7.8587g/cm3. Combining covalent bonds with the melting temperature, certain ionic-bond components are created. Bismuth telluride has an indirect bandgap semiconductor bandgap at 0.145eV, electron mobility of 0.135 and hole mobility of 4.4.410-2m2/(Vs) respectively and a thermoelectric quality of coefficient of 1.610-3K.

Is Bismuth Powder Bi2Te3 Powder 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) 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 using a muffle furnace. Application Bismuth Telluride Pulver Powder Bi2Te3 Bismuth Telluride (Bi2Te3), is an efficient thermoelectric material. Because of its many potential uses, 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 topology and 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 the use electron spins 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: Different types of packing 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: could ship out by sea, air or express once payment has been received.
