high purity materials
Bismuth telluride (Bi2Te3) is a gray powder that is a compound of bismuth and tellurium lso known as bismuth(III) telluride.
It is a semiconductor, which, when alloyed with antimony or selenium, is an efficient thermoelectric material for refrigeration or portable power generation.
Bi2Te3 is a topological insulator, and thus exhibits thickness-dependent physical properties.
Properties of Bismuth Telluride Powder
Bismuth telluride is a narrow-gap layered semiconductor with a trigonal unit cell.
The valence and conduction band structure can be described as a many-ellipsoidal model with 6 constant-energy ellipsoids that are centered on the reflection planes.
Bi2Te3 cleaves easily along the trigonal axis due to Van der Waals bonding between neighboring tellurium atoms.
Due to this, bismuth-telluride-based materials used for power generation or cooling applications must be polycrystalline.
Application of Bismuth Telluride Powder
1. Used in making thermoelectric power generation materials, Semiconductor cooling device materials, etc.

1: May I get one sample before placing order?
Re: Yes, we'd like to provide sample for you. For those normal products, you just need to bear the freight; for those high value products, you just need to freight and a little product cost. When we both cooperate for some times or when you are our VIP customer, free sample will be offered when you need.
2: How and when can I get my goods after payment?
Re: For small quantity products, they will be delivered to you by international courier(DHL, FedEx, T/T, EMS, etc.) or by air. Usually it will cost 2-5 days that you can get the goods after delivery.
For large quantity products, It will cost days to weeks to come to your destination port, which depends on where the port is.
3: Is there any possible to use my appointed label or package?
