Mechanochemical synthesis of barium titanate
(Elsevier B.V., 2005-01-01)
A powder mixture of BaO and TiO2, was mechanochemically treated in a planetary ball mill in an air atmosphere for up to 4 h, using zirconium oxide vial and zirconium oxide balls as the milling medium. Mechanochemical ...
Photoluminescence in amorphous zirconium titanate
(Springer, 2004-02-01)
Photoluminescence at room temperature was observed in amorphous zirconium titanate obtained from the polymeric precursor method. This was the first time in which PL was noticed in an amorphous compound made of two network ...
Synthesis and characterization of PLZT (9/65/35) by the Pechini method and partial oxalate
(Elsevier B.V., 1998-05-01)
ZrTiO4 (ZT), obtained by the Pechini method, was used as precursor for obtaining PLZT (lead lanthanum zirconium titanate). An aqueous solution of oxalic acid was prepared with particles of ZT, Pb(NO3)(2) and La2O3. After ...
Observation of piezoelectric response on tungsten doped barium zirconium titanate ceramics
(2010-04-01)
This study describes observation of piezoelectric response of Ba(Zr 0.10Ti 0.90.O3 ceramics modified with tungsten (BZT:2W) by the mixed oxide method. According to X ray diffraction analysis, the ceramics are free of ...
Pressure-induced phase transitions in Zr-rich PbZr1-xTixO3 ceramics
(2001-08-20)
A Raman study of structural changes in the Zr-rich PbZr1-x TixO3 (PZT) system under hydrostatic pressures up to 5.0 GPa is presented. We observe that externally applied pressure induces several phase transitions in PZT ...
Sintering and characterization of PLZT (9/65/35)
(Elsevier B.V., 2000-01-01)
PLZT(9/65/35) obtained by association between the Pechini method (ZT) and partial oxalate (PLZT) was prepared. The stoichiometric phase and monophasic (cubic) PLZT obtained by calcination did not occur after sintering. The ...
Luminescence in semi-crystalline zirconium titanate doped with lanthanum
(Elsevier B.V., 2006-10-25)
This paper aims to describe the synthesis of the semi-crystalline and crystalline powder of lanthanum doped with zirconium titanate (65/35), LZT through Pechini method. The analysis done by Raman demonstrated that ...
Dielectric investigations of vanadium modified barium zirconium titanate ceramics obtained from mixed oxide method
(Elsevier B.V. Sa, 2009-06-24)
Vanadium modified barium zirconium titanate ceramics Ba(Zr(0.10)Ti(0.90))O(3):2V (BZT:2V) were prepared from the mixed oxide method. According to X-ray diffraction analysis, addition of vanadium leads to ceramics free of ...
Electrophoretic deposition of BaTi0.85Zr0.15O3 nanopowders
(ABM, ABC, ABPol, 2013-12-01)
The present study reports the results of thick films (20-130 µm) produced through electrophoretic deposition of BaTi0.85Zr0.15O3 (BTZ) nanometric powders synthesized by the Pechini's method. The BTZ powderscalcined at ...
Dielectric and ferroelectric characteristics of barium zirconate titanate ceramics prepared from mixed oxide method
(Elsevier B.V. Sa, 2008-08-25)
Barium zirconium titanate (BZT) ceramics were prepared by mixed oxide method. X-ray diffraction showed the presence of a single phase while Raman scattering confirmed structural transitions as a function of different Zr/Ti ...
