p-type bismuth telluride, thermoelectric material pellet
product description
1. MATERIAL OVERVIEW
Characteristics:
Bismuth telluride is a compound of tellurium and bismuth. When alloyed with selenium or antimony, it acts as an efficient thermoelectric material suitable for portable power generation or refrigeration. It is a narrow gap layered semiconductor with a trigonal unit cell. It mainly occurs in a rare mineral tellurobismuthite. It is produced by sealing bismuth and tellurium metals in a quartz tube under vacuum.
Applications:
Bismuth telluride finds applications in the following:
Power generation or cooling applications
Topological insulators.
Pellet Regular size: 1.6*1.6*2.0mm,1.4*1.4*1.7mm,5*5*5*5mm,10*10*10mm and so on
Also could produce small size much less than 1.00 mm like 0.35mm and so on
bar/ingot diameter is 28-35mm
We could also produce according to customer requirement
