Antimony Telluride (Sb2Te3) powder
Antimony Telluride chemical formula: Sb2TE3.Molecular weigh 626.30.Gray powder.Melting point 639.Relative density 6.5018. To dissolve, use nitric. Antimony telluride (covalent bond), ionic bonds, have a certain van Der Waals bond composition, triangular cell system, original cell is Rhombbus Hexahedron.
Telluride, which is also an alveolar layer of antimony sulfide materials, is a gray-colored crystalline liquid with a layered structure. The layer comprises two layers of atomic, antimony and three sheets of atomic protein. They are held together with weak van den Waals forces. It’s also a topological insulation and has thickness-dependent properties.
It has a rhomboid-shaped crystal structure. The crystalline substance is covalently linked atoms that form five atom thickness sheets. (In order: Te Sb Te Te) This holds the plates together via the Van der Waals Attraction. Bulk telluride, due to its lamellar architecture and weak interlamellar energies can be mechanically stripped to separate monolayers. Sb2Te3 also has the semiconductor properties of bismuth as well. The powder can be transformed to N and P types of semiconductors when it is combined with suitable dopants.

How are Antimony Telluride (Sb2Te3) powdermanufactured?
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 ° 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 was set for 4000 r/min. It took about 4 minutes. The top liquid went colorless at the end of centrifugation. To reduce the reactionant’s temperature to 100ml, centrifuge the tube with isopropanol. It was then dried for 6 hours in an oven before it became a powder of Sb2Te3.
Antimony Telluride HTML3_ Powder :
Sb2Te3 also has semiconducting capabilities, as have other antimony and bismuth binary compounds. The appropriate dopants are required to convert Sb2Te3 into N and P types of semiconductors.
In contrast to single-frequency detection for pure Sb2Te3, iron dipped Sb2Te3 allows multiple Fermi Pockets, which leads to higher mobility and carrier density.
In a pseudo-binary intermetallic Germanium Antimony Telluride System, Sb2Te3 is combined with germanium telluride.
Antimony Telluride, which is similar to bismuth informuride or Bi2Te3, can be found in solid-state refrigerators thanks to its strong thermoelectric force.
