bismuth telluride
Bismuth Telluride (Bi2Te3), a gray powdered compound semiconductor material, is briefly introduced as follows:
Physical Properties: Bismuth Telluride typically has a density ranging from 7.5 to 7.8g/cm³ and a melting point of 585℃. It exhibits good electrical conductivity but relatively poor thermal conductivity. At room temperature, it allows electrons to move on its surface without energy consumption, a property that makes it uniquely valuable in the semiconductor field.
Applications:
Thermoelectric Materials: Bismuth Telluride is an ideal material for semiconductor thermoelectric cooling and is widely used in cooling radar systems, underwater self-guided torpedoes, infrared-guided air-to-air missile seekers, as well as in thermoelectric refrigeration and thermoelectric generation.
Electronic Devices: Bismuth Telluride can be used to manufacture semiconductor cooling chips and has important applications in the refrigeration of small electronic devices, medical equipment, and more.
Material Characteristics: Bismuth Telluride has a Mohs hardness of approximately 1.81, which is relatively low. Therefore, it is susceptible to deformation, scratches, cracks, or edge damage during cutting, grinding, and other processing due to mechanical forces. This requires corresponding protective measures during processing.
