Influence of alkali reagents on phase formation and crystal morphology of hydrothermally derived lead titanate

Mechanism of hydrothermal growth of ferroelectric PZT nanowires

“…Grown typically by hydrothermal synthesis, the PX phase is of a fibrous morphology [20,[23][24][25][26], which is compatible with its highly anisotropic structure (Fig. 6a), where vacant channels go along its [001] axis leading to a substantially higher surface energy of the (001) plane [21].…”

Fabrication and dielectric properties of lead titanate nanocomposites

“…1), which were synthesized via ball-milling, vibro-milling, and hydrothermal techniques, respectively. The characteristics of each starting PT materials and their processing details are described in our previous works [21][22][23]. The powder mixtures (matrix:dispersoid ratio of 1:1) were formed into pellets by adding 3 wt.% polyvinyl alcohol (PVA) binder, prior to pressing in a pseudouniaxial die press at 100 MPa.…”

Single-crystal lead titanate perovskite dendrites derived from single-crystal lead titanate pyrochlore dendrites by phase transition at elevated temperature

“…Among the methods, the hydrothermal technique is an aqueousbased precipitation route allowing control over the nucleation, growth, and aging processes. Previous works have demonstrated that the hydrothermally synthesized lead titanate powders exhibit different crystal structures such as perovskite type [21,22], pyrochlore type [30][31][32][33], tetragonal body-centered type (also named as PX-phase) [21], and pre-perovskite type (named as Pre-PT in this paper hereafter) [7], and various morphologies (e.g. spherical, tabular, rod-shaped, tubular, and acicular), depending on the reaction conditions (e.g.…”
