Characterization of highly-oriented ferroelectric Pb_xBa_(1-x)TiO_3 [PDF]

open access: yes, 2005
Pb_xBa_(1-x)TiO_3 (0.2 ≾ x ≾ 1) thin films were deposited on single-crystal MgO as well as amorphous Si_3N_4/Si substrates using biaxially textured MgO buffer templates, grown by ion beam-assisted deposition (IBAD).

Elastic, dielectric and electromechanical properties of (Bi0.5Na0.5)TiO3-BaTiO3 piezoceramics at the morphotropic phase boundary region [PDF]

open access: yes, 2016
A systematic study of the functional properties of the (1-x)(Bi0.5Na0.5)TiO3–xBaTiO3 (BNT-xBT) piezoceramic system for 0.05 = x = 0.07 is performed. The samples are obtained through the conventional solid-state route.

Colossal Electric Conductivity in Ag-defect Ag5Pb2O6

open access: yes, 2003
Bystroem-Evers compound Ag5 Pb2O6 has been annealed at 500-540 K under flow of electric current which results in a textured structure and anisotropic colossal electric conductivity (> 10^9 ohm-1cm-1) between 210-525 K. The related physical properties are

Lead-free textured piezoceramics using tape casting: A review

open access: yesJournal of Materiomics, 2018
In this review, the evolution of textured lead-free piezoceramics has been explored, primarily focusing on the technique of templated grain growth (TGG) and reactive-templated grain growth (RTGG), as an alternative to single crystals.
