Ferroelectric properties of pyridinium tetrafluoroborate

Physical Review B, 1994
The differential thermal analysis of a single crystal of pyridinium tetrafluoroborate was performed revealing two solid-solid phase transitions at 205 and 240 K. The real part of the dielectric permittivity was measured between 190 and 290 K. The large anomaly at the higher phase transition is interpreted as the Curie point of a new ferroelectric ...

Optical Properties of Relaxor Ferroelectrics

Ferroelectrics, 2004
The optical absorption spectrum, luminescent emission and photoconductivity were investigated in single crystal PbMg1/3Nb2/3O3 and in the Pb0.91La0.09(Zr0.65Ti0.35)O3 ceramics in the wide temperature region. The spectrum of the luminescence correlates with spectrum of photoconductivity emission.

Ferroelectric properties of PbTiO3

Physica, 1962
Abstract A new method for growing single crystals of ferroelectric PbTiO3 is described. A mixture of TiO2, Pb3O4 and KF in the ratio 1 : 2.5 : 6.5 is taken in a platinum crucible and heated to a temperature of about 900°C to 950°C for about 20 hours. The melt is then slowly cooled to room temperature.

Ferroelectric properties of colemanite

Inorganic Materials, 2006
The electrical conductivity, dielectric permittivity, and loss tangent of colemanite single crystals are measured as functions of temperature, and the fractal scaling law exponent is evaluated. The origin of the colossal dielectric response of hydrogen-bonded crystals is discussed.

MECHANICAL PROPERTIES OF FERROELECTRIC CERAMIC NANOCOMPOSITES

International Journal of Nanoscience, 2005
The micro- and nano-indentation techniques and compression tests were employed to determine the mechanical properties of PZT based composites dispersed with Al 2 O 3 nano-particles for comparison. Compared with the reduced modulus, the nano-hardness, which exhibited indentation size effect (ISE), seemed to be more sensitive to the indentation depth ...

Low-temperature thermal properties of ferroelectrics

Physical Review B, 1985
Through measurements of the low-temperature thermal conductivity and specific heat, we show that two classes of ferroelectrics can be distinguished. One class exhibits behavior typical of crystalline solids and the other displays behavior identical to that seen in structural glasses.

PLZT: Precursor characterization and ferroelectric properties

Integrated Ferroelectrics, 1998
Abstract PZT and PLZT precursor solutions were prepared by a sol-gel route, varying the Zr/Ti ratio and the La doping level. They were characterized by TGA coupled with FT-IR. Reactions taking place during heat treatments are discussed. Composition of PZT and PLZT thin films was measured by RBS and their orientation determined by XRD.
