In this paper, Magnesium Calcium Titanate (MCT) powders were prepared by both conventional solid-state method and the Pechini method. 0.95MgTiO3-0.05CaTiO3 (95MCT) were chosen as the optimum stoichiometry. Microstructure and phase transformation of calcined 95MCT powders have been observed. First, the powders were prepared by conventional solid-state method and calcined at 1000°C, 1100°C and 1200°C. Second, the 95MCT powders were prepared via the Pechini method, then calcined at 900°C and 1000°C. The calcined powders were investigated by X-Ray Diffraction analysis to identify the phases developed during calcination. For both routes, it is observed that MgTiO3 is the main crystalline phase, whereas CaTiO3 and MgTi2O5 are minor phases. However, MgTi2O5 is not desired in the structure because of its negative effect on dielectric properties. Powders produced by the Pechini method were observed to have different microstructures than conventionally produced powders.

Dielectric and piezoelectric properties of PZT ceramics doped with strontium and lanthanum Kalem, Volkan; Çam, İbrahim; Timucin, Muharrem (Elsevier BV, 2011-05-01) PZT based piezoelectric ceramics obtained by doping with various levels of Sr2+ and La3+, designated as PSLZT, were prepared by conventional processing techniques. The effects of Sr2+ and La3+ additions, and that of the Zr/Ti ratio on microstructure, on phase constitution, and on the dielectric and piezoelectric properties were investigated. XRD data revealed that all PSLZT compositions had perovskite structure in which increasing Sr and/or decreasing Zr/Ti ratio increased the tetragonality. In PSLZT cerami...
Polystyrene-organoclay nanocomposites prepared by melt intercalation, in situ, and Masterbatch methods Yılmazer, Ülkü; Ozden, G (Wiley, 2006-06-01) In this study, polystyrene (PS)/montmorillonite nanocomposites were prepared by melt intercalation, in situ polymerization, and masterbatch methods. In the masterbatch method, as the first step, a high clay content composite of PS-organoclay (masterbatch) was prepared by in situ polymerization, and then the prepared masterbatch was diluted to desired compositions with commercial PS in a twin-screw extruder. The structure and mechanical properties of the nanocomposites were examined. X-ray diffraction (XRD) ...
PORE-SIZE DISTRIBUTIONS IN URANIUM-DIOXIDE AND URANIUM DIOXIDE-GADOLINIUM OXIDE FUEL KERNEL PRODUCED BY SOL-GEL TECHNIQUE Gündüz, Güngör; ONAL, I; DURMAZUCAR, HH (1991-02-01) Small kernels of UO2-Gd2O3 were produced from their nitrate solutions by the application of sol-gel process in place of the more conventional process of mixing powders. The sol-gel method consisted of the following steps: sol preparation, sol drop dispersion, gellation, washing of gelled microspheres, aging, drying, calcination, reduction, and sintering. The effect of reduction temperature (873, 1073 and 1773 K) under a reducing gas mixture of 50% H-2 + 50% N2 on pore volume and pore size distribution, was...
Nanoceria supported palladium(0) nanoparticles: Superb catalyst in dehydrogenation of formic acid at room temperature Akbayrak, Serdar; TONBUL, YALÇIN; Özkar, Saim (Elsevier BV, 2017-06-05) Highly efficient dehydrogenation of formic acid (FA) at room temperature was achieved using palladium(0) nanoparticles supported on nanoceria (Pd-0/CeO2) as catalysts. Pd-0/CeO2 was prepared by impregnation of palladium(II) ions on the surface of ceria followed by their reduction with sodium borohydride in aqueous solution at room temperature. Pd((0)/CeO2 was isolated from the reaction solution by centrifugation and characterized by a combination of advanced analytical techniques. The catalytic activity of ...
Synthesis and characterization of polystyrene clay nanocomposites Özden, Gülsüm; Yılmazer, Ülkü; Department of Chemical Engineering (2004) This study was undertaken to prepare polystyrene (PS)/montmorillonite (MMT) nanocomposites by different methods, including melt intercalation, in-situ polymerization and masterbatch methods. The in-situ polymerization method consisted of dispersing the styrene monomer into the galleries of MMT followed by subsequent polymerization. The PS/MMT nanocomposites formed by melt intercalation method were prepared on a twin-screw extruder. The masterbatch method was in fact a two-step process. As the first step, a ...
