High Purity Antimony Telluride Powder Sb2Te3 Cas 1327-50-0, 99.99%

Antimony Telluride sb2Te3 powder

Chemical formula of antimony telluride: Sb2TE3.Molecular mass 626.30.Gray hard.Melting temperature 639.Relative density 6.5018. In nitric acids, dissolve. Antimony Telluride is a covalent (ionic) bond that has a particular van der Waals structure, triangular cell system and the original cell of rhombus Hexahedron.

Telluride, which is similar to other alveolar-sulfide layered antimony materials, is a grayish crystalline solid that has a multilayered structure. Two atomic antimony, three atomic protein sheets form the layer. The weak van der Waals force holds it together. The topological insulator is also used. It has thickness-dependent physical property.

A rhomboid crystal structure is found in Sb2Te3. The crystal material is composed of five covalently bound atoms. These sheets form five atom thick (in order: Te–Sb–Te–Te), which hold the plates together by Van der Waals attraction. Because of its lamellar shape and weak interlamellar force, bulk telluride is easily mechanically separated to remove the monolayers. Sb2Te’s semiconductor properties include the ability to separate monolayers from antimony and bismuth. You can convert it to N-type, and even P-type semiconductors if you use the right dopants.

How does Antimony Telluride SB2Te3 () powder be made?

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. At 4000r/min the speed of the centrifuge was adjusted to 4 min. After centrifugation was completed, the liquid in the top became clear. At room temperature the temperature of reactant is decreased to 100 ml per centrifuge tube. After centrifugation, the centrifugal with isopropanol is centrifuged. The black precipitate was dried in the oven for six hours. Finally, the powder became blackened Sb2Te3.

Antimony Telluride sb2Te3 powder

Sb2Te3 has been examined in the same way as other binary chalcogenides of bismuth or antimony. By adding the right dopants, it can be made into N-type and P type semiconductors.

Comparable to the single frequency detection of pure Sb2Te3, iron doped Sb2Te3 creates many Fermi pockets which results in lower carrier density.

The pseudo-binary intermetallic germanium and antimony telluride system is made up of Sb2Te3 as well as germanium telluride, (GeTE).

Antimony telluride can be used in solid-state fridges, just like Bi2Te3 and bismuth telluride. This is because it has strong thermoelectric properties.

Antimony Telluride sb2Te3 powder storage condition:

You should keep the reservoir closed and store it in a dry, cool place.
