Tin Telluride (IV-VII compound semiconductor material) is made of IVA element Sn, and VIA component TE. SnTe is its molecular formula. Particle Size: -80mesh and -100mesh Purity: 99.99% About Tin telluride NeTe powder 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 0.60eV. Tin Telluride can be described as a semiconductor substance. A sodium chloride structure and ionic crystals have a specific covalent bond element. 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 (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 the aperture carriers that is lower than 1.5 10 20 cm-3. Also known as the SNET phase, this is Tin Telluride. The NaCl samples are contaminated with tin Telluride at both room temperature and atmospheric pressure. They are called -SNE. Although the SNTE is transformed to –SNTE and orthogonal phases, and spatial groups PNMA, ­-SNTE remains. A phase change causes an increase in 11%, while the resistance of the “-SNET” increases by 360%. Teti has a thermoelectric property. Research suggests that Tin telluride SnTe powder may have a particularly high n-type efficiency. Here are some features about Tin telluride Te powder Keep the mixture at room temperature and low pressure. Use caution around open flames, heat, and light. Use semiconductor-based water to dissolve.

How does Tin telluride SnTe Powder get made? 1. The high-purity ruthenium and high-purity Tin should be weighed. After placing the ampoule into a furnace to warm (around 50 ° C/h to 435° C), heat 72 hours, and then turn off the furnace. Once the furnace has been turned off, the ampoule will be slowly chilled, until the temperature of room is reached. 2. You will weigh the high-purity, pure tin, and high-purity, ruthenium. Then, place the ampule into a sealed quartz container. Place the ampoule into a cold oven, quickly heat (about 200°C /h of 810°C), and let cool for about 15 hours. 3. As the electrolytic cells, use 1L of the round-neck three-neck flask. The cathode measures 5 mm diameter by 7cm length 7cm, purity 99.99% semiconductor material, and 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 used 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 must be boiled under an argon atmosphere to encourage precipitation. You must not let crystallization be made in the air. After crystallization, remove it from air. The crystals can then be washed, centrifuged, dried at 120°C for 4 hours, and dried with an argon flow. Tin Telluride SnTe Powder Use high-purity inorganics in electronics for display, screen, and catalyst.
