Aluminum Telluride

Al2Te3

Aluminum Telluride Al2Teor Triturium Dialuminium, CAS 12043-29-7, MW 436.76, density 4.5g/cm3, no odor, is gray-black hexagonal crystal, and stable at room temperature, but decomposes into hydrogen telluride and aluminum hydroxide in humid air. Aluminum Telluride Al2Te3,can be formed by reacting Al and Te at 1000°C, the binary system Al-Te contains the intermediate phases AlTe, Al2Te3 (α-phase and β-phase) and Al2Te5, The crystal structure of α- Al2Teis monoclinic. Aluminum Telluride Al2Te3 is mainly used for pharmaceutical raw material, semiconductor and infrared material. Aluminum Telluride Al2Te3 at Western Minmetals (SC) Corporation with 4N 99.99% and 5N 99.999% purity is available in form of powder, granule, lump, chunk, bulk crystal etc or as customized specification with vacuum package by bottle or composite bag.

Arsenic Telluride

As2Te3

Arsenic Telluride or Arsenic Ditelluride As2Te3, a group I-III binary compound, is in two crystallographic Alpha-As2Te3 and Beta-As2Te3, among which Beta-As2Te3 with rhombohedral structure, exhibits interesting thermoelectric (TE) properties by adjusting the content of alloys. Polycrystalline Arsenic Telluride As2Te3 compound synthesized by powder metallurgy may be an interesting platform to design novel TE materials with high efficiency. Single crystals of As2Te3 is prepared hydrothermally by heating and gradually cooling a mixture of stoichiometric quantities of powdered As and Te in a HCl 25% w/w solution. It is mainly used as semiconductors, topological insulators, thermoelectric materials. Arsenic Telluride As2Te3 at Western Minmetals (SC) Corporation with purity of 99.99% 4N, 99.999% 5N can be delivered in form of powder, granule, lump, chunk, bulk crystal etc or as customized specification.

Bismuth Telluride

Bi2Te3

Bismuth Telluride Bi2Te3, P type or N-type, CAS No 1304-82-1, MW 800.76, density 7.642 g/cm3, melting point 5850C, is synthesized by vacuum smelting- controlled crystallization process namely with the Bridgman-Stockbarber method and Zone-floating method. As thermoelectric semiconductor material, the Bismuth Telluride pseudo binary alloy presents the best characteristics for room temperature thermoelectric cooling applications for miniaturized versatile cooling devices in a wide spectrum of equipments and energy generation in space vehicles. By using appropriately oriented single crystals instead of polycrystalline, the efficiency of the thermoelectric device (Thermoelectric Cooler or Thermoelectric Generator) could be increased greatly, which can be founded in semiconductor refrigeration and temperature difference power generation filed, and also for optoelectronic devices and Bi2Te3 thin film material. Bismuth Telluride Bi2Te3 at Western Minmetals (SC) Corporation is in size of powder, granule, lump, rod, substrate, bulk crystal etc to be delivered with 4N 99.99% and 5N 99.999% purity.

Gallium Telluride

GaTe

Gallium Telluride Ga2Te3  is a hard and brittle black crystal with  MW 522.24, CAS 12024-27-0, melting point of 790℃ and density 5.57g/cm3. Single crystal Gallium Telluride GaTe is developed by using different growth techniques such as Bridgman Growth, Chemical Vapor Transport CVT or Flux Zone Growth to optimize grain size, defect concentration, structural, optical, and electronic consistency. But Flux zone technique is a halide free technique used for synthesizing truly semiconductor grade vdW crystals, which distinguishes itself from Chemical Vapor Transport CVT technique to ensure slow crystallization for perfect atomic structure, and impurity free crystal growth. Gallium Telluride GaTe is a layered semiconductor belonging to the III-VI metal compound crystal with two modifications, which are stable α-GaTe of a monoclinic and metastable β-GaTe of hexagonal in structure, good p-type transport properties, a direct band-gap of 1.67 eV in the bulk, the hexagonal phase converts to the monoclinic phase at high temperature. Gallium Telluride layered semiconductor possesses interesting properties attractive for future opto-electronic applications. Gallium Telluride Ga2Te3 at Western Minmetals (SC) Corporation with purity of 99.99% 4N, 99.999% 5N can be delivered in form of powder, granule, lump, chunk, rod, bulk crystal etc or as customized specification.
