Antimony Telluride (Sb2Te3) is a topological insulation with a chemical formula Sb2Te3. Particle Size: 80mesh or 100mesh
Purity: 99.99%

Antimony Telluride powder Sb2Te3
Gray solid. Melting temperature 639. Dissolve in Nitric Acid. Antimony Telluride has a van der Waals compound, triangular structure, covalent and ionic bond. The original cell is the rhombus-hexahedron.
The layer is composed of two atomic antimony and three atomic protein sheets, held together by weak van der Waals forces. The thin layer of antimony is formed by two atomic sheets of antimony, three atomic proteins and held in place by weak van Der Waals forces. It also exhibits topological insulator properties and is therefore thickness dependent.
Sb2Te3 is a rhomboid-shaped crystal. The covalently-bonded atoms in the crystalline material form five atom-thick plates (in order Te-Sb,Te-Te), and the Van der Waals attractivity holds the plates together. Bulk telluride, due to its lamellar arrangement and weak interlamellar force, can be mechanically stripped of monolayers. Sb2Te3 is also a semiconductor with antimony, bismuth and other binary cholines. With the right dopants it can be transformed into N-type and/or P-type transistors.

How does Antimony Telluride Sb2Te3 Powder get produced?
Telluride antimony preparation is as follows: using SbCl3 and K2TeO3 as starting materials, according to the stoichiometric ratio of n (SbCl3): n (K2TeO3) = 2:3 said take 0.002 mol SbCl3 and 0.003 mol K2TeO3, 250 ml and join the two round bottom flask, and then add in the 0.5 g polyvinylpyrrolidone, 80 ml 0.5 gNaOH and a reduction of diethylene glycol (take) by the measuring cylinder, put two round bottom flask temperature control heating jacket, set the temperature of 240 deg C, insulation 4 h, adjusting the rotational speed of 500 r/min.After the temperature of the reactants dropped to room temperature, the centrifuge was centrifuged 3 times with isopropyl alcohol and acetone, respectively. The centrifuge speed and time were set at 4000r/min. After centrifugation the liquid in the upper part of the tube became colorless. The temperature of reactant is lowered to 100 ml at room temperatures and centrifugal with isopropanol & acetone. After 6 hours in the oven, a black precipitate is removed. This gives a Sb2Te3 black powder.

Application and use of Antimony Telluride (Sb2Te3) powder
Sb2Te3 was also investigated for its semiconducting characteristics. It can be converted by adding the appropriate dopants to N-type and P type semiconductors.
Sb2Te3 iron-doped introduces multiple Fermi-pockets, resulting in a lower carrier densities and mobility.
Sb2Te3 with germanium telluride form a pseudobinary intermetallic Germanium Antimony Telluride System.
Antimony telluride is used, along with bismuth and Bi2Te3, in solid-state fridges due to its strong thermoelectric effect.

Condition of Antimony Telluride (Sb2Te3) powder when stored:

Be sure to keep the reservoir in a cool, dry location.
