Thermal Conduction in Ferroelectric Ceramics
Journal of the Physical Society of Japan, 1960Apparatuses were constructed and measurements were made on the thermal conductivity of insulating crystals over the temperature ranges from -200°C to 600°C. For the lower temperature range, the absolute measurement was used, while for the higher one, the comparative method was adopted.

Thinned ferroelectric crystals and ceramics
Proceedings of 1994 IEEE International Symposium on Applications of Ferroelectrics, 2002In interpreting the properties of thin film ferroelectrics, it is useful to have baseline electrical property data on thinned single crystals and ceramics over the same thickness range, In this study, the properties of thinned BaTiO/sub 3/ have been investigated. To examine the quality of the surfaces produced, spectroscopic ellipsometry (SE) was used.

Domain structure of ferroelectric ceramics
Ceramics International, 2000Abstract PZT ceramics were statically and dynamically evaluated to examine the relationship between domain structures and electrical properties. We investigated the domain structures of tetragonal, M.P.B. and rhombohedral PZT ceramics at various poling fields to measure the poling field dependence of the crystal orientations and electrical properties

The dielectric constants of a ferroelectric ceramic
Ferroelectrics, 1973The problem of estimating the dielectric constants of a ferroelectric ceramic from those of the single crystal is tackled theoretically. It is pointed out that conventional formulae, such as those that average the dielectric constant or its inverse, presuppose particular microscopic geometries and lead to great inaccuracies in the case of ...

Stress Effects in Ferroelectric Ceramics
1979Electromechanical transducers made of ferroelectric ceramic materials such as those based on barium titanate (BT) or on various lead zirconate titanate (PZT) compositions have become widely used for a variety of applications over the past 25 years [1].

Piezoelectric effects in ferroelectric ceramics
IEEE Spectrum, 1970Ferroelectric ceramics exhibit piezoelectric effects and optical birefringence that are electrically controllable. Consequently, these ceramics are applicable to a wide variety of devices. An article in the February issue has already described electrically actuated light valves and electrically controlled optical filters. The present article deals with

Transparent Ferroelectric Glass-Ceramics
Ferroelectrics, 2004In recent years, there has been a resurgence of interest in transparent ferroelectric glass-ceramics (TFGCs), which are a special class of glass-ceramic composites that combine the low cost of fabrication and forming of transparent glass with the superior nonlinear optical and electro-optical properties of ferroelectric crystals.
