Poling strategy of PLZT ceramics

Ferroelectrics, 1984
Abstract The best conditions of poling are reported for PLZT 8/65/35 and 12/40/60 ceramics. Selection of different poling parameters has been studied as well as their influence on aging. Results are in accordance with the classical concept of domain switching.

Holographic storage and photoconductivity in PLZT ceramic materials

Applied Optics, 1976
The dynamics of holographic recording in quadratic electrooptic materials are analyzed. High optical quality PLZT ceramic is found to conform to the behavior predicted for quadratic materials. The operation of PLZT as a holographic store and as a photoconductor is studied, and mechanisms that limit the material sensitivity are postulated.

Aging of Strontium Barium Niobate and PLZT Ceramic

Physica Status Solidi (a), 1980
SBN 75 and PLZT 8/65/35, two ferroelectrics with different structure and symmetry which exhibit diffused phase transition, show similar aging effects: a lessening of the dielectric losses and of the dielectric dispersion by lowering the low-frequency dielectric constant (DC), a doubling of the hysteresis loop within the slim loop region, a lowering of ...

PLZT ceramic numeric display devices

1974 International Electron Devices Meeting (IEDM), 1974
The longitudinal fringe-field electrooptic effect in slim-loop lead lanthanum zirconate titanate (PLZT) ceramics offers the best known possibility of using ferroelectric ceramics for low-voltage, high-contrast numeric and alphanumeric display devices. Such devices appear feasible using either transmitted or reflected ambient light.

Microstructure of organometallic derived PLZT ceramics

Journal of the European Ceramic Society, 2001
The PLZT powders with the formula Pb 0.905 La 0.095 (Zr 0.65 Ti 0.35 ) 0.976 O 3 + 3.5 wt.% PhO were prepared by the organometallic precursor method (Pechini and partial oxalate processes). The microstructure of sintered 9.5/65/35 PLZT ceramics obtained from a partial oxalate procedure shows that the outstanding feature of this microstructure is its ...

The shape-memory effect in PLZT ceramics

Ferroelectrics, 1981
Abstract The shape-memory effect has been investigated in ferroelectric-ferroelastic PLZT ceramic samples of composition 6.5/65/35 by bending and twisting experiments and temperature cycling. The effect of an electric field on the shape memory produced by bending is also examined. During the course of these experiments some additional evidence was also

Some special properties of PLZT ceramics

Ferroelectrics, 1978
The increase of the elastic compliance s11 of PLZT during cooling through Tc is discussed in terms of the model developed by Smolensky et al. for ferroelectrics with diffuse phase transition. The decrease of s11 and of the mechanical quality with increasing biasing field strength above Tc, as well as some peculiarities during polarization reversal ...

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.

Excitation and emission of Pr3+:PLZT ceramics

Ceramics International, 2016
Abstract Excitation and emission spectra of Pr 3+ :PLZT ceramics have been studied. Several emission bands were measured under blue laser excitation, which correspond to 3 P 0 → 3 H 4 , 1 D 2 → 3 H 4 , 3 P 0 → 3 H 4 and 3 P 0 → 3 F 2 transitions of trivalent Pr 3+ . Their integrated emission intensities were determined.

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.
