Impedance response and dielectric relaxation in liquid-phase sintered Zn 2SnO 4-SnO 2 ceramics
(Springer US, 2010)
Impedance/admittance and dielectric spectroscopy were used to investigate the effect of temperature on the electrical response of liquid-phase sintered Zn 2SnO 4-SnO 2 ceramics. The measurements were performed over a wide ...
Electret state in Bi4Ti3O12 ceramics
The effect of thermal treatment atmosphere (argon, air or oxygen) on the electret behavior of bismuth titanate (Bi4Ti3O12) ceramics was investigated. Polycrystalline ferroelectric ceramics were prepared by reactive liquid ...
Electrical properties of barium titanate stannate functionally graded materials
Barium titanate stannate (BTS) functionally graded materials (FGMs) with different tin/titanium concentration gradient were prepared by the powder-stacking method and uniaxially pressing process, followed by sintering. ...
Structural and electrical properties of barium-zinc-titanate ceramics sintered at 1300ºc
(Belgrade : Institute of Technical Sciences of SASA, 2010)
The aim of this work was an investigation of structural and electrical properties of sintered barium-zinc-titanate ceramics. Mixtures of BaCO3, ZnO and TiO2 were mechanically activated in a planetary ball mill up to 80 ...
Intergranular fractal impedance analysis of microstructure and electrical properties of rare-earth doped BaTiO3
(Hoboken, NJ : John Wiley & Sons, 2010)
Microstructure properties of barium-titanate based materials, expressed in grain boundary contacts, are of basic importance for electric properties of these material. In this study, the model of intergranular impedance ...
