Textured Li2O · 2SiO2 glass ceramics

Journal of Non-Crystalline Solids, 1996
Abstract Textured glass ceramics of Li2O · 2SiO2 composition were prepared with a highly oriented microstructure. This orientation was achieved by surface crystallization and by volume crystallization moving the glass through a temperature gradient. The microstructure was determined by scanning electron microscopy. Quantitative texture investigations

Textured Lead-Free Piezoelectric Ceramics for Flexible Energy Harvesters.

ACS Applied Materials and Interfaces, 2023
A lead-free (K,Na)NbO3-based piezoelectric ceramic is textured along the (001) direction using the NaNbO3 (NN) seeds. The composition 0.96(K0.5Na0.5)(Nb0.965Sb0.035)O3-0.01CaZrO3-0.03(Bi0.5K0.5)HfO3 (KNN) is found to provide an excellent combination of ...

Preparation of textured Bi3TiNbO9 ceramics

Materials Chemistry and Physics, 2007
Abstract Single phase of textured Bi3TiNbO9 (BTNO) ceramics were prepared by a two-step sintering method: synthesizing seed-crystal platelets by molten-salt method with oxide mixture as precursor and then sintering the platelets via hot-pressing method. Molten-salt-synthesized fine BTNO plate-like crystallines (∼400 nm) had an orientation degree of 0.

Anisotropic Properties in Textured Ceramics

Materials Science Forum, 1998
Preferred orientation results from processing of many ceramic and intermetallic materials. Preferred orientation of crystals, anisometric grain shapes and oriented defects can enhance or compromise the performance of ceramic components. The limited research to date on textured ceramics has focused on either materials for structural applications or for ...

Textured BiScO3-PbTiO3 piezoelectric ceramics with both high electromechanical coupling factor and high curie temperature

Applied Physics Letters, 2023
High-temperature piezoelectric devices require piezoelectric ceramics with high Curie temperatures and high-temperature stability of piezoelectric properties to avoid the depolarization of piezoelectric ceramics during application. However, piezoelectric

Templated Grain Growth of Textured Piezoelectric Ceramics

Critical Reviews in Solid State and Materials Sciences, 2004
ABSTRACT Crystallographic texturing of polycrystalline ferroelectric ceramics offers a means of achieving significant enhancements in the piezoelectric response. Templated grain growth (TGG) enables the fabrication of textured ceramics with single crystal-like properties, as well as single crystals.

Textured α-SiAlON Ceramics via Templated Grain Growth

Materials Science Forum, 2007
In this study, textured α-SiAlON ceramic was produced by templated grain growth process. In order to enhance the alignment of the seeds, gated tape casting arrangement was utilized. Y-Ce codoped seeds were synthesized to induce the preferred orientation. For the production of the seeds, Ce3+ was used as a sintering additive due to its well-known effect
