On the design of a piezoelectric self-sensing smart composite laminate

open access: yesMaterials & Design, 2022
The structural health monitoring of composite laminates is a rapidly emerging need in structural applications. Different real-time sensors integrated into laminates have been proposed, such as fiber Bragg gratings and piezoceramics.

Birefringence of lead titanate (PbTiO3) [PDF]

open access: yesJournal of Applied Crystallography, 2004
Since lead titanate was first grown in single-crystal form in the 1930s, several independent reports of its linear birefringence have been published. Whilst there is overall qualitative agreement on its behaviour with temperature, the absolute values show some degree of variation.

Topotatic‐Like Phase Transformation of Amorphous Lead Titanate to Cubic Lead Titanate

open access: yesJournal of the American Ceramic Society, 2002
The crystallization process of lead titanate (PT) prepared using the polymeric precursor method was investigated using X‐ray diffractometry, Raman spectroscopy, electron microscopy, and X‐ray absorption spectroscopy techniques. The results showed that amorphous PT was formed by an O–Ti–O structure composed of fivefold and sixfold oxygen‐coordinated ...

The preparation of a novel layered lead titanate and its conversion to the perovskite lead titanate PbTiO3 [PDF]

open access: yesMaterials Research Bulletin, 2001
A novel layered lead titanate with the approximate composition PbTiO2(CO3)0.3(NO3)0.35(OH) has been synthesized hydrothermally under acidic conditions. The structure has been solved and refined from X-ray and neutron powder diffraction data in the space group P -3 1 m, with cell dimensions a = 5.1787(5) Å and c = 8.5222(7) Å.

Magnetic and electric properties of bismuth ferrite lead titanate ceramics [PDF]

open access: yes, 2010
Solid solutions of multiferroic BiFeO3 doped with ferroelectric PbTiO3 (BFPT) can be prepared by conventional mixed oxide processing to produce a range of polycrystalline ceramics ranging throughout the xBiFeO3 - (1-x)PbTiO3 series. Sintered ceramics are

Highly efficient lead zirconate titanate ring modulator

open access: yesAPL Photonics
Advanced photonic integrated circuits require large-scale integration of high-speed electro-optic (EO) functional components on a chip. Low power consumption and high operation speed are thus key metrics for almost all integrated EO devices.
