Dense mullite–zirconia–zirconium titanate ceramic composites by reaction sintering
(Elsevier, 2016-01)
Materials from the Al2O3-SiO2-ZrO2 and the Al2O3-SiO2-ZrO2-TiO2 systems have several high temperature applications because they present the good refractoriness, chemical inertness, adequate mechanical and thermo-mechanical ...
Thickness dependence of structure and piezoelectric properties at nanoscale of polycrystalline lead zirconate titanate thin films
(2013-05-14)
Lead zirconate titanate Pb(Zr0.50Ti0.50)O3 (PZT) thin films were deposited by a polymeric chemical method on Pt(111)/Ti/SiO2/Si substrates to understand the mechanisms of phase transformations and the effect of film thickness ...
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 ...
Sintering and Microwave Properties of Zirconium Tin Titanate Doped with Select Oxides
(SPRINGERNEW YORK, 2012)
Zirconium tin titanate (ZST) is often used as a dielectric resonator for the fabrication of microwave devices. Pure compositions do not sinter easily by solid state sintering; therefore, sintering ZST requires sintering ...
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 ...
Structural and functional characterization of barium zirconium titanate/epoxy composites
(2011)
The dielectric behavior of composite materials (barium zirconium titanate / epoxy system) was analyzed as a function of ceramic concentration. Structure and morphologic behavior of the composites was investigated by X-ray ...
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 ...
Microscopic and dielectric analyses of vanadium and tungsten modified barium zirconium titanate ceramics
(2010-12-01)
Dielectric spectroscopy was used in this study to examine polycrystalline vanadium and tungstendoped BaZr 0.1Ti 0.90O 3 (BZT10:2V and BZT10:2W) ceramics obtained by the mixed oxide method. According to X-ray diffraction ...
