Description of Tin telluride SnTe Powder：

Tin Telluride (IV-VI) compound semiconductor material comprises IVA element Sn VIA element T. The molecular formula of SNTE. It is an asynchronous transmitting type, and the banned bandwidth is 0.60eV.

Tin Telluride can be described as a semiconductor substance. A sodium chloride structure and ionic crystals have a covalent bond component. Density 6.48g / cm3, melting 780 degrees Celsius. The material is made using an epitaxial and straight pull method.

Tin Telluride is often alloyed with tiny lead lisuride to create the infrared detection material. Tin Telluride forms an external semiconductor, the p-type (external semiconductor), due to the presence of tin in its air. This superconductor is low-temperature.

Tin Telluride can be found in all three phases of the crystal. Low temperatures result in a concentration of less than 1.5 x 10-20 cm-3 for the aperture carrier. Also known as the "a-SNET" phase, it is found in the diamond stage. The NaCl samples are labeled b-SNE. Tin TELLURIDE, found at room temperature and atmospheric pressure, can be detected in NaCl samples. Although the bSNTE is transformed into gSNTE and orthogonal phases, it also forms part of the spatial group PNMA. This phase change causes an 11% rise in the resistance and a 360% increase in the strength of the g-SNET. Teti, a thermoelectric substance, is also known as Teti. Research suggests that the n-type performance might be excellent. If you are interested in buying Tin Telluride, SnTe powder wholesale, please inquire.

Production Method of Tin telluride SnTe powder ：

Direct synthesis

Direct synthesis is a commonly used tin telluride production method, which directly reacts tin and telluride at high temperatures to obtain tin telluride. The specific steps are as follows:

The higher-purity tin and tellurium elements are prepared; tin is usually present in bulk or granular form, and tellurium is generally present in powder form.

Place blocks or particles and tellurium powder into quartz tubes, ensuring both ends are closed.

The quartz tube is placed in a heating furnace and heated to the appropriate temperature (usually 600-800 ° C). Keep the temperature high (e.g., several hours) to allow the tin and tellurium to react fully.

After the reaction, the quartz tube is removed, cooled, and opened to reveal the resulting tin telluride crystals.

The advantages of direct synthesis are simple operation and easy availability of raw materials. However, it should be noted that the purity of tin telluride obtained by this method may not be high enough, and further purification is needed. In addition, the direct synthesis method has a higher cost and is unsuitable for mass production.

Electrolysis

Electrolysis is a method of preparing compounds by electrolysis of a solution, which can be used to produce high-purity tin telluride. The specific steps are as follows:

Dissolve an appropriate amount of tin salts (such as tin nitrate) and tellurium salts (such as tellurium chloride) in a solvent (such as water) to obtain a mixed solution.

The mixture is poured into the cell, and a voltage is applied to both electrodes.

During electrolysis, tin and tellurium ions are reduced to tin and tellurium on the anode and deposited on the cathode to form tin telluride.

The tin telluride deposited on the cathode is collected for cleaning and drying.

The advantage of electrolysis is that high-purity tin telluride can be prepared, and the cost is relatively low, which is suitable for large-scale production. In addition, tin telluride can be controlled by electrolysis by adjusting the solution concentration and electrolytic conditions. However, it should be noted that the electrolysis method requires electrolytic equipment, and the operation is more complicated.
