Indium antimony

Robertson [ 57 ] has measured the adsorption of zinc, caesium, strontium, antimony, indium, iron, silver, copper, cobalt, rubidium, scandium, and uranium onto glass and polyethylene containers. Radioactive forms of these elements were added to samples of seawater, the samples were adjusted to the original pH of 8.0, and aliquots were poured into polyethylene bottles, Pyrex-glass bottles and polyethylene bottles contained 1 ml concentrated hydrochloric acid to bring the pH to about 1.5. Adsorption on the containers was observed for storage periods of up to 75 d with the use of a Nal(Tl) well crystal. Negligible adsorption on all containers was registered for zinc, caesium, strontium, and... 

Figure 1 shows phase diagram of indium and antimony. Indium and antimony formed indium antimonide alloy at compositional ratio of 50 at.% 50 at.%, and formed eutectic structure of Indium antimonide and antimony at compositional ratio of 70 at.% 30 at.%. 

Several p-block compounds have been employed in this acid-amine coupling reaction these include bismuth, indium and antimony. Indium metal has been found useful for the N-formylation of amines. This reaction requires only 10 mol% indium catalyst and can be used for formic acid reactions with amino alcohols resulting in no side reaction on the alcohol terminus. Electron-rich triarylbismuthanes have been reported to couple carbo>ylic acids to amines within reaction times of 12 hours. In numerous cases, high yields were obtained although little amine scope is explored and in some cases where hindered carbojq lic acids were used, only starting materials were recovered. ... 

An electrolyte of this type has been used to synthesize alkyl derivatives of tin, zinc, antimony, indium, magnesium [74-77], silicon, and germanium [78] (Table 8). It is interesting to note that an attempt to synthesize organogermanium compounds on a germanium single crystal as anode was unsuccessful [86]. 

Solders. In spite of the wide use and development of solders for millennia, as of the mid-1990s most principal solders are lead- or tin-based alloys to which a small amount of silver, zinc, antimony, bismuth, and indium or a combination thereof are added. The principal criterion for choosing a certain solder is its melting characteristics, ie, soHdus and Hquidus temperatures and the temperature spread or pasty range between them. Other criteria are mechanical properties such as strength and creep resistance, physical properties such as electrical and thermal conductivity, and corrosion resistance. 

Metallic Antimonides. Numerous binary compounds of antimony with metallic elements are known. The most important of these are indium antimonide [1312-41 -0] InSb, gallium antimonide [12064-03-8] GaSb, and aluminum antimonide [25152-52-7] AlSb, which find extensive use as semiconductors. The alkali metal antimonides, such as lithium antimonide [12057-30-6] and sodium antimonide [12058-86-5] do not consist of simple ions. Rather, there is appreciable covalent bonding between the alkali metal and the Sb as well as between pairs of Na atoms. These compounds are useful for the preparation of organoantimony compounds, such as trimethylstibine [594-10-5] (CH2)2Sb, by reaction with an organohalogen compound.

Of the elements commonly found in lead alloys, zinc and bismuth aggravate corrosion in most circumstances, while additions of copper, tellurium, antimony, nickel, silver, tin, arsenic and calcium may reduce corrosion resistance only slightly, or even improve it depending on the service conditions. Alloying elements that are of increasing importance are calcium especially in maintenance-free battery alloys and selenium, or sulphur combined with copper as nucleants in low antimony battery alloys. Other elements of interest are indium in anodesaluminium in batteries and selenium in chemical lead as a grain refiner ".

The in-V compounds combine the elements of Group HI (aluminum, gallium, indium) with those of Group V (phosphorus, arsenic, antimony, bismuth). As can be imagined, a wide variety of compounds can be produced which, in addition to the binary materials, also include ternary and even quaternary materials. 

Complexes of other metals such as gallium, indium, lead, and antimony have also been used as Lewis acids. Catalytic enantioselective meso-epoxide ring-opening reactions using a chiral gallium(III) catalyst (Ga-Li-linked-BINOL) have been reported (Scheme 84).348 The chemical yields are much improved by linking two BINOL units. 

The colorless tris(0-ethyl dithiocarbonato)arsenic(III) and yellow antimony(III) complexes have been prepared from the corresponding metal trichlorides using this procedure. Tris-(alkyl trithiocarbonato)-, tris(0,0 -dialkyldithiophosphato)-, and other tris(0-alkyl dithiocarbonato)indium(III) complexes can undoubtedly be prepared from the potassium or sodium derivatives of the ligands using this procedure. 

X-ray powder diagrams obtained by the Guinier method show the tris (O-ethyl dithiocarbonato) complexes of chro-mium(III), indium(III), cobalt(III), iron(III), arsenic(III), and antimony(III) to be isomorphous. Carrai and Gottardi have determined the structure of the arsenic(III)18 and anti-mony(III)19 complexes. Crystallographic data for the cobalt(III) and chromium(III) ethylxanthate complexes are given by Derenzini20 and Franzini and Schiaffino,21 respectively.
