Formation and thermal decomposition of indium oxynitride compounds
Tokarzewski,Podsiadlo
, p. 481 - 488 (1998)
During the reactions of lithium oxide with indium nitride, lithium nitride with indium oxide, and lithium nitride with lithium indate LiInO2, the formation of a previously unknown crystalline phase, of composition Li4InNO2, was observed. The course of thermal decomposition of the new compound was determined.
EFFECTIVE SUPPORTED-In2O3 FOR THE PRODUCTION OF HYDROGEN FROM WATER BY THE REDUCTION-OXIDATION CYCLE OF In2O3
Otsuka, Kiyoshi,Shibuya, Shin-ichi,Morikawa, Akira
, p. 987 - 990 (1982)
Eleven kinds of carriers for In2O3 have been tested for the production of hydrogen from water by a reduction and oxidation cycle of In2O3.Of these, the most effective carriers were TiO2, ZrO2, active carbon and ZnO, because the high enchancing effects on the rates of reduction and oxidation and the high final yields of hydrogen by the reduced In2O3 have been observed by usihg these carriers.
Electrodeposition of indium onto Mo/Cu for the deposition of Cu(In,Ga)Se2 thin films
Valderrama,Miranda-Hernández,Sebastian,Ocampo
, p. 3714 - 3721 (2008)
A study of the electrodeposition and the oxidation process of indium on Mo/Cu substrates from a bath containing 0.008 M InCl3, 0.7 M LiCl at pH 3 is described in this work. The voltamperometric study showed a reduction process which corresponds to the conversion of In3+ to In0 and an oxidation process which takes place in different steps. Utilizing the chronoamperometric technique the total efficiency of process, the number of monolayers, the film thickness and the diffusion coefficient were evaluated. The analysis of current transients, using theoretical growth model, showed that the electrodeposition of indium adjusts to a three-dimensional growth under instantaneous nucleation limited by diffusion. The kinetic growth parameters were evaluated through a non-linear fit. The films were characterized by X-ray diffraction and scanning electron microscopy techniques. These studies showed that the films were of crystalline in nature with compact and uniform surface, even for the film with a deposition time of 1 min.
Pressure-induced decomposition of indium hydroxide
Gurlo, Aleksander,Dzivenko, Dmytro,Andrade, Miria,Riedel, Ralf,Lauterbach, Stefan,Kleebe, Hans-Joachim
, p. 12674 - 12678 (2010)
A static pressure-induced decomposition of indium hydroxide into metallic indium that takes place at ambient temperature is reported. The lattice parameter of c-In(OH)3 decreased upon compression from 7.977(2) to ～7.45 A at 34 GPa, corresponding to a decrease in specific volume of ～18%. Fitting the second-order Birch-Murnaghan equation of state to the obtained compression data gave a bulk modulus of 99 ± 3 GPa for c-In(OH)3. The c-In(OH)3 crystals with a size of ～100 nm are comminuted upon compression, as indicated by the grain-size reduction reflected in broadening of the diffraction reflections and the appearance of smaller (～5 nm) incoherently oriented domains in TEM. The rapid decompression of compressed c-In(OH)3 leads to partial decomposition of indium hydroxide into metallic indium, mainly as a result of localized stress gradients caused by relaxation of the highly disordered indium sublattice in indium hydroxide. This partial decomposition of indium hydroxide into metallic indium is irreversible, as confirmed by angle-dispersive X-ray diffraction, transmission electron microscopy imaging, Raman scattering, and FTIR spectroscopy. Recovered c-In(OH)3 samples become completely black and nontransparent and show typical features of metals, i.e., a falling absorption in the 100-250 cm-1 region accompanied by a featureless spectrum in the 250-2500 cm-1 region in the Raman spectrum and Drude-like absorption of free electrons in the region of 4000-8000 cm-1 in the FTIR spectrum. These features were not observed in the initial c-In(OH) 3, which is a typical white wide-band-gap semiconductor.
Synthesis, characterisation and theoretical studies of amidinato-indium(I) and thallium(I) complexes: Isomers of neutral group 13 metal(I) carbene analogues

The synthesis and characterisation of the monomeric amidinato-indium(I) and thallium(I) complexes, [M(Piso)]PisoH, M = In or Tl, Piso- = [ArNC(But)NAr]-, Ar = C6H3Pr 2i-2,6, are reported. These complexes, in which the metal centre is chelated by the amidinate ligand in an N,η3-arene- fashion, can be considered as isomers of four-membered group 13 metal(I) carbene analogues. Theoretical studies have compared the relative energies of both isomeric forms of a model complex, [In{PhNC(H)NPh}]. The Royal Society of Chemistry 2005.

Reduction of indium(III) oxide to indium through mechanochemical route
Kano, Junya,Kobayashi, Eiko,Tongamp, William,Saito, Fumio
, p. 204 - 205 (2008)
A nonthermal reduction of indium(III) oxide (In2O3) to metallic indium (In) was achieved through mechanochemical route in this work. A mixture of In2O3 and lithium nitride (Li3N) under ammonia (NH3) and/or nitrogen (N2) gas environments was milled in a planetary ball mill with uni-size ZrO2 balls to induce mechanochemical reaction between the starting materials. Metallic indium was obtained after milling for 120 min, and the results are confirmed by X-ray diffraction (XRD) analysis. Washing of the milled product with water to remove by-products using the planetary ball mill for a further 10 min resulted in formation of pellets which were analyzed by EPMA, results clearly show that high purity indium metal was obtained.

Synthesis of group 13 sesquialkoxides and their application as precursors to crystalline oxide films

The reaction of Me3Ga with an excess of 4-methylbenzyl alcohol (4-MeC6H4CH2OH) in toluene, under reflux conditions, resulted in the formation of the sesquialkoxide [Ga{MeGa(OCH 2C6H4Me-4)3}3] (1). In contrast, reaction of Me3In with excess of 4-methylbenzyl alcohol (4-MeC6H4CH2OH) under the same conditions afforded another type of sesquialkoxide, [In{Me2In(OCH 2C6H4Me-4)2}3] (2). Compounds 1 and 2 have been characterized by NMR, FTIR, and elemental analysis, and the structure of 1 was determined by X-ray crystallography. The structure of 1 consists of a central Ga3+ ion coordinated by three [MeGa(OCH 2C6H4Me-4)(μ-OCH2C 6H4Me-4)2]- units such that it has a coordination number of six. The surrounding metal ions are four coordinate. 1H NMR data for 1 indicate that in solution two isomers (1:1) are present, namely, the C1- and C3-symmetrical isomers, but in the solid state 1 exists as the C3-symmetrical isomer. Compound 1 possesses the correct ratio of Ga:O atoms (2:3) for that found in gallium oxide (Ga2O3), and LPCVD of 1 afforded crystalline Ga 2O3 films at 600°C. These results are surprising, as Ga2O3 films are typically only crystalline above 700°C.
