Lead zirconate titanate ceramics with aligned crystallite grains

Science, 2023
The piezoelectric properties of lead zirconate titanate [Pb(Zr,Ti)O 3 or PZT] ceramics could be enhanced by fabricating textured ceramics that would align the crystal grains along specific orientations. We present a seed-passivated texturing process to fabricate textured PZT ceramics by using newly developed Ba(Zr ...

Lead titanate zirconate — based pyroelectric ceramics

Ceramurgia International, 1978
Abstract Ceramics with a base composition PbTlxZr1−xO3 (x = 0.07) and modified materials by additions of Nb2O5, Fe2O3 and U3O8 In ≤ 1 wt. % concentration were pressure sintered to near theoretical densities. The effect of these additives on the microstructure and on the dielectric properties are reported and discussed in terms of the A- and O ...

Refatigue of Ferroelectric Lead Zirconate Titanate

Journal of the American Ceramic Society, 2010
Bipolar fatigue of ferroelectric lead zirconate titanate ceramics can be partly recovered by thermal annealing. For samples of initially, intermediately, or highly fatigued state, subsequent refatiguing yields a much more rapid decay in polarization and piezoelectric constant than the initially nonfatigued samples despite very ...

Lead titanate and lead zirconate titanate piezoelectric glass-ceramics

Ferroelectrics, 1994
Abstract The crystallization behavior and electrical properties of a piezoelectric glass-ceramic system consisting of lead titanate (PT) or lead zirconate titanate (PZT) in a lead borosilicate matrix is presented. Glass powders of compositions in this system densify at 650°C, and crystallize the ferroelectric PT or PZT phases.

Layered lead zirconate titanate and lanthanum-doped lead zirconate titanate ceramic thin films

Journal of Materials Research, 2002
The physical layering of sol-gel-derived lead zirconate titanate (PZT) 52/48 and lanthanum-doped PZT (PLZT) 2/52/48 on platinized silicon substrates was investigated to determine if the ferroelectric properties and fatigue resistance could be influenced by different layering sequences.

Fractoemission from Lead Zirconate‐Titanate

Journal of the American Ceramic Society, 1985
We present measurements of the electron, positive ion, and photon emission accompanying the fracture in vacuum of poly‐crystalline 95/5 lead zirconate‐titanate. The intensities of the charged‐particle components of this fractoemission are shown to depend strongly on the direction (relative to the direction of fracture) and magnitude of polarization ...

Unipolar fatigue of ferroelectric lead–zirconate–titanate

Journal of the European Ceramic Society, 2003
In multilayer actuators the ferroelectric material is known to degrade under bipolar and to some degree under unipolar electric loading. Fatigue effects due to unipolar cycling of a commercial bulk lead–zirconate–titanate up to 4·108 cycles at 2 Ec are demonstrated. Unipolar as well as bipolar polarisation and strain hysteresis loops are measured after
