Electrical properties of niobium doped barium bismuth-titanate ceramics
(Pergamon-Elsevier Science Ltd, Oxford, 2012)
BaBi4Ti4-5/4xNbxO15 (BBNTx, x = 0.0.05, 0.15, 0.30) ceramics have been prepared by solid state method. XRD data indicate the formation of single-phase-layered perovskites for all compositions. SEM micrographs suggest that ...
The electrical properties of chemically obtained barium titanate improved by attrition milling
(Springer, New York, 2013)
Barium titanate ceramics were prepared using the nanopowder resulting from a polymeric precursor method, a type of modified Pechini process. The obtained nanopowder was observed to agglomerate and in order to de-agglomerate ...
Dielectric and ferroelectric properties of BST ceramics obtained by a hydrothermally assisted complex polymerization method
(Elsevier Sci Ltd, Oxford, 2015)
Ba0.8Sr0.2TiO3 (BST) powder, obtained by a hydrothermal treatment of precursor solution previously prepared by a complex polymerization method (HT-CPM), was uniaxially pressed and sintered at 1280 degrees C for 1-32 h. The ...
Impedance Response and Dielectric Relaxation in Liquid-Phase Sintered Zn2SnO4-SnO2 Ceramics
(Springer, New York, 2010)
Impedance/admittance and dielectric spectroscopy were used to investigate the effect of temperature on the electrical response of liquid-phase sintered Zn2SnO4-SnO2 ceramics. The measurements were performed over a wide ...
Dielectric and magnetic properties of BaTiO3-NiFe2O4 multiferroic composites
(Elsevier Sci Ltd, Oxford, 2014)
Multiferroic composites with the general formula x BaTiO3-(1-x) NiFe2O4 (x=0.5, 0.7, 0.8) were prepared by mixing chemically obtained nickel ferrite and barium titanate powders. Optimum processing parameters for a reduction ...
Dielectric and ferroelectric properties of Ho-doped BiFeO3 nanopowders across the structural phase transition
(Elsevier Sci Ltd, Oxford, 2017)
We have studied Ho-doped BiFeO3 nanopowders (Bi1-xHoxFeO3, x = 0-0.15), prepared via sol-gel method, in order to analyse the effect of substitution-driven structural transition on dielectric and ferroelectric properties ...
Donor-acceptor joint effect in barium titanate systems
(Elsevier Sci Ltd, Oxford, 2015)
Modified Pechini process was used to prepare nanopowders of barium titanate (BT) co-doped with different concentrations of niobium and manganese. Influence of dopants on the grain growth inhibition and microstructure ...
Structural and electrical properties of sintered Fe2O3/TiO2 nanopowder mixtures
(Elsevier Sci Ltd, Oxford, 2014)
Starting nanopowders of TiO2 (anatase 99.7%) and alpha-Fe2O3 (hematite) were mixed in the weight ratios 60:40 and 40:60. Green samples were sintered in the temperature range 750-1250 degrees C in air. Structural, morphological ...
Properties of lanthanum doped BaTiO3 produced from nanopowders
(Elsevier Sci Ltd, Oxford, 2010)
Pure and barium titanate (BT) powders doped with different lanthanum concentration were prepared by the polymeric precursor method (Pechini process) which was carried out as a three-stage process from organometallic ...
Effect of La substitution on the structural and electrical properties of BaBi4-xLaxTi4O15
(Elsevier Sci Ltd, Oxford, 2013)
Pure and lanthanum doped barium bismuth titanate BaBi4-xLaxTi4O15 (BBLT, x=0, 0.05, 0.15, 0.30) ceramics were prepared utilizing solid state method. The X-ray diffraction (XRD) data confirmed formation of single-phase ...
