Product Description
1.Product Description
|
Characteristics:
|
Bismuth telluride is a compound of tellurium and bismuth. It is a narrow gap layered semiconductor with a trigonal unit cell. It mainly occurs in a rare mineral tellurobismuthite. It's produced by sealing bismuth and tellurium metals in a quartz tube under vacuum.
When alloyed with selenium or antimony, it acts as an efficient thermoelectric material suitable for portable power generation or refrigeration. |
|
Production Processes:
|
Vacuum melting - crystallization (crystal orientation growth) - regional melting - removal of both ends;
|
|
Applications:
|
Forming P/N section for semiconductor refrigeration, thermoelectric power generation, etc.
