Preparation and characterization of nanosized SrBi2Nb2O9 powder by the combustion synthesis
(Elsevier B.V., 2003-06-01)
This work presents the preparation of SrBi2Nb2O9 (SBN) directly by the combustion synthesis. Strontium nitrate, niobium ammonium oxalate (NH4H2[NbO-(C2O4)(3)].3H(2)O) and bismuth oxide were used as oxidant reactants and ...
Room-temperature photoluminescence of BaTiO3: Joint experimental and theoretical study
(Amer Physical Soc, 2005-02-01)
Strong photoluminescent emission has been measured at room temperature for noncrystalline BaT'O-3 (BT) perovskite powders. A joint experimental and theoretical study has been carried out to rationalize this phenomenon. ...
Influence of seed particle frequency on the phase formation and on the microstructure of 0.88 PZN-0.07 BT-0.05 PT ceramic
(Elsevier B.V., 2000-01-01)
The Pechini method as well as the simultaneous addition of seeds particles and dopant solutions of BaTiO3 (BT) and PbTiO3 (PT) were used to prepare the perovskite phase 0.88 PZN-0.07 BT-0.05 PT. To study the influence of ...
Influence of the LiNbO3 and KNbO3 seeds on the sintering and electrical properties of PMN ceramic
(Taylor & Francis Ltd, 2002-01-01)
The effect of LiNbO3 and KNbO3 seeds on the microstructure and dielectric characteristics of PMN ceramic prepared by columbite route have been investigated with the addition of 0, 1, and 2-wt% of seeds. X-ray diffraction, ...
Mechanochemical synthesis of PZT powders
(Elsevier B.V., 2003-03-25)
PZT ceramic powders were successfully prepared from the mixture of PbO, ZrO2 and TiO2 by mechanochemical synthesis in a planetary ball mill, under different milling conditions. Phase evolution during synthesis was monitored ...
Microwave synthesis of calcium bismuth niobate thin films obtained by the polymeric precursor method
(Elsevier B.V., 2006-08-10)
The crystal structure, surface morphology and electrical properties of layered perovskite calcium bismuth niobate thin films (CaBi2Nb2O9-CBN) deposited on platinum coated silicon substrates by the polymeric precursor method ...
Structural and dielectric relaxor properties of yttrium-doped Ba(Zr0.25Ti0.75)O-3 ceramics
(Elsevier B.V. Sa, 2010-05-15)
In this work, [Ba1-xY2x/3](Zr0.25Ti0.25)O-3 ceramics with different concentrations (x = 0, 0.01, 0.025 and 0.05) were synthesized by Solid state reaction. The X-ray diffraction patterns indicated that these crystalline ...
