Useful:

• Chemical Classes: Metals -> Mercury Compounds, Inorganic
• Canonical SMILES: [Te]=[Hg]
• Uses: Mercury cadmium telluride (MCT)is the mostim- portantmaterial currently in use for the manufacture of high performance infrared (IR) detectors. Mercury telluride and mercury telluride-cadmium telluride are semiconductors which have been investigated as intrinsic infrared detecting materials. Complete coverage of the low-loss fiber windows by mercury telluride quantum dot are used in colloidal nanocrystals for telecommunications. Semiconductor in solar cells, thin-film transistors, infrared detectors, ultrasonic amplifiers.

Technology Process of Mercury telluride

There total 46 articles about Mercury telluride which guide to synthetic route it. The literature collected by LookChem mainly comes from the sharing of users and the free literature resources found by Internet computing technology. We keep the original model of the professional version of literature to make it easier and faster for users to retrieve and use. At the same time, we analyze and calculate the most feasible synthesis route with the highest yield for your reference as below:

synthetic route:

Reference yield: 95.0%

triethylphosphane telluride (2935-45-7) + diphenylmercury(II) (587-85-9,1337-09-3) + triethylphosphine (554-70-1) → mercury(II) telluride (12068-90-5,37248-20-7) + diphenyl ditelluride (32294-60-3) + diphenyl telluride (1202-36-4)

Guidance literature:

In toluene; Addn. of Ph2Hg-soln. and Et3P to Et3PTe soln. and Et3P, heating of mixt. at reflux for 20 h, HgTe pptd.; GC, X-ray powder diffraction.;

Reference yield: 95.0%

tellurium (14683-12-6) + mercury(II) oxide (12653-71-3) → mercury(II) telluride (12068-90-5,37248-20-7)

Guidance literature:

In ethylenediamine; components (2-8% chalcogen excess) mixing in solvent, stirring at ca. 12°C for 6-16 h; ppt. collection, washing (H2O, EtOH), vac. drying at 80°C for 2 h;
