PLZT—Synthesis, sintering and ceramics microstructure

Journal of the European Ceramic Society, 2006
Abstract Producing of PLZT powders by original two-stage co-precipitation method from mixed solution of inorganic salts ZrOCl 2 ·8H 2 O, TiCl 4 , La(NO 3 ) 3 ·6H 2 O, Pb(NO 3 ) 2 , was carried out. The sequence of phases formed during PLZT synthesis has been studied by X-ray and DTA analysis.

Laser-induced selftransparency in PLZT ceramics

Ferroelectrics, 1988
Abstract We report measurements of selftransparency effects in PLZT 8/65/35 ceramics for various wavelength of laser radiation λ = 0. 5+6 νm. The results are interpreted in terms of thermally induced phase transitions, thermal lens and photorefraction in PLZT. Optimal conditions for the light-by-light control in PLZT 8/65/35 are achieved and discussed.

Diffuse critical point in PLZT ceramics

EPL (Europhysics Letters), 2013
The ferroelectric transition line in the electric-field temperature phase diagram of the canonical relaxor ferroelectric ceramics 9/65/35 PLZT has been studied via polarization and high-resolution heat capacity measurements. The modified calorimetric relaxation measurements show a change of the sample temperature if the applied electric field is ...

Far infrared properties of PLZT ceramics

Journal of Materials Science, 1997
Far infrared and mid infrared reflectivity measurements have been made of lead titanate zirconate (PLZT) ceramics at room temperature in the frequency range 40–1500 cm-1. Kramers-Kronig analysis and a fitting procedure based on a four parameter model of the spectrum, determined the infrared active transverse and longitudinal optical modes and their ...

Photostrictive Actuator Using PLZT Ceramics

Japanese Journal of Applied Physics, 1985
Photostriction explainable by the superposition of the bulk photovoltaic effect and piezoelectricity has been investigated in the solid solution ceramics of (Pb, La)(Zr, Ti)O3. Using the optimum composition PLZT(3/52/48), we have fabricated a photodriven relay as a trial photostrictive actuator.

Evaluation of PLZT ceramics for applications in optical communications

Optics Communications, 1972
Abstract An evaluation is made to determine the suitability of fine grained ferroelectric ceramic Pb 0.91 La 0.09 Zr 0.65 Ti 0.35 O 3 (PLZT) for applications in optical modulators. It was found that the electro-optic materials and comparisons of the electrode geometries suitable for ceramics and for single crystals are made.

Asymmetry of electroconductivity in polarized plzt ceramics

Ferroelectrics, 1986
Asymmetry of electroconductivity in PLZT X/65/35 ferroelectric ceramics has been observed. The density of steady-state current for one direction of field applied along the remanent polarization was 2-5 times larger than the current density in the opposite field direction.

Elastic Properties of Rhombohedral PLZT Ceramics

Japanese Journal of Applied Physics, 1989
Elastic compliance constants, elastic stiffness constants, electro-mechanical coupling coefficients, mechanical losses and thermal expansion coefficients have been obtained for lanthanum doped lead zirconate-titanate ceramics having composition of (X/65/35) with X=1 to 7.5 (abbreviated to rhombohedral PLZT) over a temperature range including the ...

Grain boundary structures in plzt ceramics

Ferroelectrics, 1989
Abstract Some possible atomic structural models of the grain boundary in PLZT transparent ferroelectric ceramics were constructed according to the HREM image photomicrographs taken near the grain boundary from a high resolution electron microscope. These models give not only a clear picture of the grain boundary structure in PLZT ceramics, but can also

Holographic Storage in Quadratic PLZT Ceramics

Journal of the American Ceramic Society, 1974
Photoinduced changes in refractive index in a quadratic electrooptic PLZT ceramic were observed. Thick‐phase holograms were recorded with high diffraction efficiency (η∼ 0.10 to 0.50). The dependencies of the diffraction efficiency on the density of light energy and applied field were determined.
