Product Description
MATERIAL OVERVIEW
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. |
| Storage Conditions: |
Keep the reservoir sealed and stored in a cool and dry place.Make sure that the workshop has good ventilation or exhaust devices. |
| 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. |
