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

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 methods.

Tin Telluride is often alloyed with lead tiny lisuride to create the infrared detection material. Tin Telluride forms an external semiconductor, the p type (because of the presence of tin), and it is also a superconductor at low temperatures.

Tin Telluride can be found in all three phases of the crystal. Low temperatures result in a concentration of less than 1.5x10-20 cm-3 for the aperture carrier. Also known as the "a-SNET" phase, it is found in the diamond stage. The NaCl samples are labelled b-SNE. Tin TELLURIDE, which is found at room temperature and atmospheric press, can be detected in NaCl samples. The bSNTE is transformed to gSNTE. This phase change causes an 11% rise in the phase and increases the resistance by 360%. Teti, a thermoelectric substance, is also known as Teti. Research suggests that the n-type performance might be very good. If you are interested in buying Tin telluride, SnTe powder wholesale, please send us an inquiry.

How does Tin telluride snTe be produced?
1. The high-purity tin, ruthenium and chemical measurement mixture should be weighed. After placing the ampoule into a furnace to warm (about 50°C / h to 435°C, heating 72 h), the ampule was turned off and allowed the temperature of the room to cool down.
2. The high-purity, pure tin, and the ruthenium according to their chemical measurement ratio are weighed. Seal the container under high vacuum (10-5 Pa). Place the ampoule into a cold oven, quickly heat (approximately 200 degrees C/h of 810 degree C), and let cool for about 15 hours.
3. As the electrolytic cells, use 1 L of the round-neck three-neck flask. The cathode measures 5 mm diameter by 7 cm in length and is 99.99% pure. The anode is a cylindrical high purity Tin bottle. You should seal the glass and metal. This port allows you to connect and add the mechanical vacuum pump. The magnetic stirrer inside the bottle is placed into the botulfluoroethylene and stirred during electrolysis. An NH4AC–HAC buffer solution is used. To bring the pH up to 4.5, you can add 500 ml (1 mol /L) ammonia. To start electrolysis, you must place the flask of electrode in the vacuum. After 30 minutes, adjust the magnetic force and stir the mixture for 30 minutes. In the anode, SnTe is precipitated in Sn2+ solution.
4. You can also add the electrolyte to the anode. The metal salt solution (such a chloride) can be droppedwise and is used in 101.325 KPa pure Argon with Platinum.
The electrolyte's precipitate is heated in an argon environment to encourage precipitation. You must not let crystallization be made in the air. After crystallization, remove it from air. The crystal is then washed, centrifuged, dried at 120 degrees C, for 4 hours, and finally dried with an argon flow.
