Preparation of lead zirconate titanate (Pb(Zr0.52Ti0.48)O-3) by homogeneous precipitation and calcination

Oren, EE
Tas, AC
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 titanate (Pb(Zr0.52Ti0.48)O-3) by homogeneous precipitation and calcination
Tas, AC (1999-06-01)
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 ...

Synthesis of tempo containing chiral polymers for kinetic resolution of secondary alcohols.
Yücel, Ece Ayç; Akdağ, Akın; Department of Chemistry (2020)
Optically pure secondary alcohols are important building blocks for the synthesis of chemicals used in pharmaceutical sciences. Kinetic resolution of secondary alcohols through selective oxidation of one enantiomer to the corresponding ketone is a classical and efficient method to obtain enantiopure alcohols. An oxidative kinetic resolution is achieved by exploiting two enantiomers’ unequal rates of oxidation reaction with a chiral reagent or catalyst. The general approach towards a kinetic resolution via a...
Extraction of some transition metals with N,N-dibutyl-N '-benzoylthiourea into molten paraffin at 65 degrees C
Merdivan, M; Gungor, A; Savasci, S; Aygün, Rüveyde Sezer (2000-10-02)
The solid-liquid extraction behaviour of some transition metals (Cu(II), Co(II), Ni(II), Cd(II) and Pb(II)) by the use of N,N-dibutyl-N'-benzoylthiourea as an extractant in paraffin (58-60 degrees C) has been investigated at 65.0 +/- 0.5 degrees C. The effect of equilibration time, pH of the aqueous phase, concentration of extractant and solid solvent used on the extraction efficiency of these metals have been discussed. The interferences of various ions are examined. The method has been applied to the dete...
Preparation and microstructure of sol-gel derived silver-doped silica
Akkopru, Betul; Durucan, Caner (2007-08-01)
Silver-doped silica was prepared by hydrolysis and condensation of tetraethyl orthosilicate (TEOS, Si(OC2H5)(4)) in the presence of a silver nitrate (AgNO3) solution by two different synthesis methods. In the first synthesis route, sol-gel mixtures were prepared using an acid catalyst. In the second synthesis route, silver-doped silica gels were formed by two-step acid/base catalysis. For the same concentration of silver dopant [AgNO3]/[TEOS] = 0.015 acid-catalyzed sol-gel formed a microporous silica with a...
