Preparation of phase-pure PZT (Pb(Zr0.52Ti0.48)O-3) powders was achieved, in the presence of urea (CH4N2O), by homogeneous precipitation. Aqueous solutions of PbCl2, ZrOCl2. 8H(2)O, and TiCl4 were used as the starting materials in the synthesis of phase-pure PZT powders. Phase evolution behavior of precursor powders was studied by powder X-ray diffraction (XRD) in air, over the temperature range of 90 degrees to 750 degrees C. The morphology of the formed powders was studied by scanning electron microscopy (SEM). Semiquantitative chemical analyses of the samples were performed by energy-dispersive X-ray spectroscopy (EDXS).

Preparation of lead zirconate titanate (Pb(Zr0.52Ti0.48)O-3) by homogeneous precipitation and calcination Oren, EE; Tas, AC (1998-05-06) Aqueous solutions of lead chloride (PbCl2), zirconium oxychloride (ZrOCl2.8H(2)O) and titanium tetrachloride (TiCl4), in appropriate volumetric amounts, were used as the starting materials in the synthesis of phase-pure Pb(Zr0.52Ti0.48)O-3 powders. Preparation of the phase-pure PZT powders were achieved, in the presence of urea (CH4N2O), by the chemical powder synthesis route of homogeneous precipitation.
Preparation of lead zirconate by homogeneous precipitation and calcination Oren, EE; Taspinar, E; Tas, AC (1997-10-01) Antiferroelectric PbZrO3 has been synthesized by homogeneous precipitation from aqueous solutions in the presence of urea (NH2CONH2) and calcination for 6 h at 700 degrees C. SEM studies displayed the presence of submicrometer powder, with a significant degree of agglomeration.
Characterization of degradation products of polyethylene oxide by pyrolysis mass spectrometry Fares, M.M.; Hacaloğlu, Jale; Suzer, S. (1994-01-01) The techniques of direct and indirect (evolved gas analysis) pyrolysis MS are used to characterize the thermal degradation products of polyethylene oxide. Using direct pyrolysis MS technique the main degradation process is determined to be due to C~ and C~C scissions yielding fragments characteristic of the polymer. Evolved gas analysis indicates formation of small molecular stable compounds such as C2H•OCzH 5, CH3CHO, CO,, CO and C2H 4.
PREPARATION OF Pb(Zr,Ti)O-3 THIN FILMS AND POWDERS BY THE SOL-GEL PROCESS Ozenbas, Macit; Ergin, Umit (Informa UK Limited, 1996-01-01) The present paper describes the preparation of Pb(Zr,Ti)O-3 thin films and powders from metal chlorides by homogeneous precipitation using urea. The rate of decomposition of urea is very slow and the particles formed are very small in size (micron-sized) and highly homogeneous in composition. The coating of the films was carried out on alumina and silicon substrates in an ambient atmosphere. Heat treatment temperatures in excess of 800 degrees C were required to ensure that the perovskite phase dominated in...
Use of Seydisehir alumina as a support for Co oxidation catalysts Mbaraka, I; Üner, Deniz (2003-05-01) An Al2O3 sample obtained from Seydisehir Eti Aluminyum A.S was treated and characterized for its potential use as a catalyst support. Atomic absorption spectroscopy and flame photometry characterization revealed the presence of 95.52% Al2O3 , 4.44% Na2O, and 0.043% Fe2O3 in the original sample. Both gamma-Al2O3 and alpha-Al2O3 phases were identified in the crystalline structure by X-ray diffraction analysis. However, alpha-Al2O3 was found to be the phase in abundance. The BET surface area of the original sa...
