2.Product Descriptions

 

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

 

1. It is commonly used in physical vapor deposition processes, Thermal analysis test cup, Aluminum die-casting mould coating;

2. II-VI compound semiconductor materials, thermoelectric converting elements;

3. Refrigeration elements, piezo crystal and infrared detectors, test instruments, chemical vapor deposition.
