thermoelectric element pellet bi2te3 n p type bismuth telluride cubes

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.
