Antimony selenides

The phase diagram and the thermodynamic properties of the liquid phase in the antimony-selenium system were assessed by Ghosh, Lukas, and Delaey [89GHO/LUK] and by Ghosh [93GHO]. Sb2Sc3(cr) is the only intermediary compound in the system.

Stibine is readily oxidized and may be ignited in the presence of air or oxygen to form water and antimony trioxide at lower temperatures metallic antimony and water are slowly formed. Sulfur and selenium react with stibine at 100°C in the presence of light to form antimony trisulfide [1345-04-6], Sb2S3, and antimony selenide [1315-05-5], Sb2Se3, respectively. At elevated temperatures stibine reacts with most metals to give antimonides. Heavy metal salts react with stibine to produce dark, metallic-appearing precipitates. In the case of silver nitrate, silver antimonide is first formed, and this reacts in turn with additional silver nitrate to produce metallic silver and antimony trioxide ... 

The crystal structures of the high-temperature modifications of -sodium antimony sulphide and /3-sodium antimony selenide, determined by X-ray methods, are isotypic and possess a fee lattice of the NaCl type with a statistical distribution of (Na + Sb) atoms in the Na" positions and of S (or Se) atoms in the Cr positions. Crystal data are space group Fm3m for each, a = 5.7748, 5.965 A d(expt.) = 3.54, 4.68 d(calc.) = 3.60, 4.73 Z = 2, 2 for /8-NaSbS2 and -NaSbSe2, respectively. The low-temperature modifications o -NaSbS2 and a-NaSbSe2 are not isostructural and exhibit lower symmetry. Atoms of Na and Sb in... 

The electrolyte in the measurements of the thermodynamic properties of bismuth sele-nide and telluride and of antimony telluride was the easily melted mixture of anhydrous zinc chloride (analytic purity) with sodium and potassium chlorides (chemical purity grade). The melting point of this mixture was Tmp — 208 C. The thermodynamic properties of antimony selenide were determined using a mixture of aluminum chloride (distilled twice in vacuum) and sodium chloride (chemical purity grade). The meltii point of this mixture was Tmp = 150-155°C.

Metals less noble than copper, such as iron, nickel, and lead, dissolve from the anode. The lead precipitates as lead sulfate in the slimes. Other impurities such as arsenic, antimony, and bismuth remain partiy as insoluble compounds in the slimes and partiy as soluble complexes in the electrolyte. Precious metals, such as gold and silver, remain as metals in the anode slimes. The bulk of the slimes consist of particles of copper falling from the anode, and insoluble sulfides, selenides, or teUurides. These slimes are processed further for the recovery of the various constituents. Metals less noble than copper do not deposit but accumulate in solution. This requires periodic purification of the electrolyte to remove nickel sulfate, arsenic, and other impurities. 

Both antimony tribromide and antimony ttiiodide are prepared by reaction of the elements. Their chemistry is similar to that of SbCl in that they readily hydroly2e, form complex haUde ions, and form a wide variety of adducts with ethers, aldehydes, mercaptans, etc. They are soluble in carbon disulfide, acetone, and chloroform. There has been considerable interest in the compounds antimony bromide sulfide [14794-85-5] antimony iodide sulfide [13868-38-1] ISSb, and antimony iodide selenide [15513-79-8] with respect to their soHd-state properties, ferroelectricity, pyroelectricity, photoconduction, and dielectric polarization.

Diselenium dication 145a was formed by the reaction of the corresponding bis-selenide 144 with a 1 2 mixture of sulfuryl chloride and antimony pentachloride (see Equation 41) <1997JS01006>. 

Sulfides of arsenic and antimony are brightly colored, which has given rise to their use as pigments. Some of the sulfides, selenides, and tellurides of arsenic and antimony also function as semiconductors. 

Selenium is extracted as diethyldithiocarbamate complex from the solution containing citrate and EDTA [5]. Ohta and Suzuki [6] found that only a few elements, such as copper, bismuth, arsenic, antimony, and tellurium, are also extracted together with selenium. They examined this for effects of hundredfold amounts of elements co-extracted with the selenium diethyldithiocarbamate complex. An appreciable improvement of interferences from diverse elements was observed in the presence of copper. Silver depressed the selenium absorption in the case of atomisation of diethyldithiocarbamate complex, but the interference of silver was suppressed in the presence of copper. The atomisation profile from diethyldithiocarbamate complex was identical with that from selenide. 

Antimony telluride films have been grown from antimony(III) and tellurium(IV) oxides.167 Antimony telluride films were stoichimetric and consisted of nanoscale particles of the size 100 nm. The films had a good crystallinity.167 Indium selenide films were grown from indium sulphate and selenium oxide precursors.168 The films consisted of large particles, 70 to 200 nm in diameter. The band gap was 1.73 eV.168...

Sulfides, Antimonides, Selenides, and Tellurides are minerals in which sulfur, antimony, selenium, or tellurium combine with one or more metals, or with one metal and one semi-metal. Some sulfide minerals are valuable sources of such elements as copper, silver, zinc, and mercury.
