ISSN: 1573-4846Keywords: PZT ; film ; powder ; thermal phase evolution ; Pb-precursorSource: Springer Online Journal Archives 1860-2000Topics: Chemistry and PharmacologyNotes: Abstract PZT (PbZr0.53Ti0.47O3) films and powders have been prepared by a precursor mixture containing Pb(NO3)1.5EO3 (EO3=triethylene glycol) and Zr- and Ti-methoxy ethanolates. The gel films have been deposited on Si/Ti/Pt substrates and on glass substrates from which they can easily be removed. The PZT films on the Si/Ti/Pt substrates were prepared with thicknesses up to 200 nm per layer after heating to 700°C. The phase development on heat-treatment of loose gel films to yield PZT was investigated by Powder-XRD, FT-IR, SEM-EDS, TEM-EDS, thermo-mass spectroscopy and DSC and the PZT was found to form in the region 550–700°C. PZT powders of 50–5000 nm sizes were prepared by hydrolysis under basic conditions and washing with water followed by heat-treatment to 650°C.Type of Medium: Electronic ResourceURL: -

ISSN: 1573-4846Keywords: hydrolysis ; Mn-Sb-ethoxides ; FT-IR ; structureSource: Springer Online Journal Archives 1860-2000Topics: Chemistry and PharmacologyNotes: Abstract The hydrolysis-condensation pathways of Mn2Sb4(OEt)16 in various ethanol-toluene solvents have been studied for h 〈 1.5 (h = H2O/Mn2Sb4(OEt)16). The hydrolysis was performed by slow addition of H2O diluted with the ethanol-toluene solvent. Mn2Sb4(OEt)16 and its hydrolysis products were studied by FT-IR spectroscopy, SEM-EDS and single-crystal X-ray diffraction. The hydrolysis pathway for a given h-value was found to depend on the solvent composition. In ethanol-rich solvent mixtures, Mn7Sb4O4(OEt)18(HOEt)2 was obtained in maximum yield at h = 1.14, and in toluene-rich solvents, Mn8Sb4O4(OEt)20 was obtained in maximum yield at h = 1.0. In both cases, the remaining Sb was found as nonhydrolyzed Sb(OEt)3. The structures of the heterometallic ethoxides Mn2Sb4(OEt)16, Mn7Sb4O4(OEt)18(HOEt)2 and Mn8Sb4O4(OEt)20 have been determined earlier by single-crystal X-ray diffraction. According to FT-IR evidence the molecular structures of the latter two are retained almost intact in solution, whereas the first one changes appreciably. The hydrolysis products of Mn2Sb4(OEt)16 are compared with those of Ni2Sb4(OEt)16, and the structural and compositional changes in different solvents and at different h-values are discussed.Type of Medium: Electronic ResourceURL: -
14Processing of ZnO-Based Varistors Using Oxide, Alkoxide, Nitrato-Alkoxide and Carboxylato PrecursorsStaff View
ISSN: 1573-4846Keywords: ZnO-varistor ; sintering ; grain growth ; solution routesSource: Springer Online Journal Archives 1860-2000Topics: Chemistry and PharmacologyNotes: Abstract We have investigated the preparation of ZnO varistors by different chemical solution routes with the aim of improving the homogeneity of the phases formed and to obtain a better control of microstructure. One conventional oxide mixing route and four solution chemical routes have been used to prepare the precursor materials. In all cases, the same composition (mol%) was used; ZnO (95.9), Bi2O3 (1), Sb2O3 (1), NiO (1), Co2O3 (0.5), MnO (0.5), Cr2O3 (0.1). The same sintering procedure was also applied. It was found that the precursor materials consisting of ZnO grains covered by a thin film of the additive oxides yielded smaller ZnO grains. Also the microstructure in the final compacts was improved, compared with that of compacts prepared from oxide mixing routes. The smaller ZnO grain size in the final compacts was attributed to the presence of spinel grains. The spinel grains are formed at lower temperatures and, when they reach a size of 1 μm, they hinder the growth of ZnO grains.Type of Medium: Electronic ResourceURL: -

ISSN: 1573-4846Keywords: hydrolysis pathway ; Ni-Sb-ethoxides ; soI-gelSource: Springer Online Journal Archives 1860-2000Topics: Chemistry and PharmacologyNotes: Abstract The hydrolysis-condensation pathways of Ni-Sb-ethoxides in different toluene-ethanol solvents have been studied. The hydrolysis was performed by slow addition of controlled amounts of water, diluted in toluene-ethanol solvents. Characterization of the hydrolysis products was performed with single crystal X-ray determinations, IR-spectroscopy, UV-Vis spectroscopy and TGA. In this way, a number of different Ni-Sb-(oxo)-ethoxides have been isolated and characterized. It was thereby shown that the Ni∶Sb ratio of the hetero bimetallic oxoalkoxides varied much depending on the degree of hydrolysis and that the species formed vary with the solvent used and the speed at which the water is added.Type of Medium: Electronic ResourceURL: -

ISSN: 1573-4803Source: Springer Online Journal Archives 1860-2000Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision MechanicsNotes: Abstract Binary alkoxide complexes of compositions close to MSb(OEt)5, with M = Mn, Fe, Co and Ni, have been prepared and characterized by their i.r. and u.v.-VIS spectra, while Cr, Cu and Zn do not form similar ethoxide complexes with Sb(OEt)3. The Mn and Fe complexes must be prepared in inert atmosphere as they are very easily oxidized. The Fe complex is metastable and decomposes within a few hours. The Co complex can only be prepared in the presence of acetonitrile. X-ray amorphous gels were formed upon hydrolysis of solutions containing M to Sb species in the ratio 1∶2 for M = Mn, Fe, Co and Ni. The gels consisted of agglomerated particles of sizes from 75 to 300 nm. The decomposition of the gels in air and in nitrogen has been monitored by means of thermogravimetric measurements. Samples of heated gels were quenched from various temperatures in the region 50–950°C, and the formed oxides were characterized by their X-ray powder patterns and by their infrared spectra. At 950 °C MSb2O6 was formed in air, while in nitrogen MSb2O4 (M = Mn, Co and Ni) was formed at intermediate temperatures. At higher temperatures the latter compound decomposed and Sb2O3 sublimated.Type of Medium: Electronic ResourceURL: -

ISSN: 1573-4846Keywords: solution processing ; nano-phase nickel ; film ; spongeSource: Springer Online Journal Archives 1860-2000Topics: Chemistry and PharmacologyNotes: Abstract Routes to nano-phase nickel in the forms of highly porous sponges and dense films have been developed. Nickel acetate and nitrate were mixed with triethanolamine and methanol, and evaporated to a concentrated liquid. Heat-treatment at 10°C/min to 170°C under N2 atmosphere yielded a highly porous sponge consisting of 〈10 nm sized Ni crystallites. Deposition of a 1 M nickel precursor solution on polycrystalline Al2O3, SnO2 : F coated glass or titanium substrates spinning at 2700 rpm, followed by heat-treatment at 10°C/min to 400°C yielded smooth and dense nickel films consisting of 3–5 nm sized crystallites. The precursor concentrate was studied by FT-IR and the phase development on heat-treatment was studied by thermogravimetric analysis, powder X-ray diffraction, scanning and transmission electron microscopy.Type of Medium: Electronic ResourceURL: -
