Textured ferroelectric ceramics with high electromechanical coupling factors over a broad temperature range

Nature Communications, 2021
Only a few relaxors can be grown into crystals, which show high piezoelectricity, but their operable temperature range is limited by the low phase transition temperature.

Bismuth Sodium Titanate Based Materials for Piezoelectric Actuators [PDF]

, 2015
The ban of lead in many electronic products and the expectation that, sooner or later, this ban will include the currently exempt piezoelectric ceramics based on Lead-Zirconate-Titanate has motivated many research groups to look for lead-free substitutes.

Biomimetic microtextured surfaces to improve tribological and antibacterial behaviors of 3Y-TZP ceramics

Journal of Materials Research and Technology, 2023
Surface texturing has been a powerful means to improve the service performance of various engineering materials. The 3 mol% yttria-stabilized tetragonal zirconia polycrystal (3Y-TZP) represents the most-used ceramic oxide in restorative dentistry due to ...

Current limiting and negative differential resistance in indium oxide based ceramics [PDF]

, 2009
Indium oxide based ceramics with bismuth oxide addition were sintered in air in the temperature range 800-1300 ºC. Current-voltage characteristics of In2O3-Bi2O3 ceramics sintered at different temperatures are weakly nonlinear.

Texture design for microwave dielectric (Ca0.7Nd0.3)0.87TiO3 ceramics through reactive-templated grain growth

Science and Technology of Advanced Materials, 2015
Plate-like Ca3Ti2O7 (CT) and Nd2Ti2O7 (NT) particles were synthesized in molten salts and used as reactive templates for the preparation of highly textured (Ca0.7Nd0.3)0.87TiO3 bulk ceramics (CNT) with preferred pseudocubic 〈100〉 and 〈110〉 orientations ...

The contribution of 211 particles to the mechanical reinforcement mechanism of 123 superconducting single domains [PDF]

, 2003
Hardness and fracture toughness of Dy-123 single-domains were studied by Vickers micro-indentation. A significant anisotropy of the mechanical properties was observed. Hardness tests give higher values when performed in (001) planes rather than in planes

An attempt to obtain Bi_{4}Ti_{3}O_{12}-PVC textured ceramics-polymer composites

, 2013
Bi_{4}Ti_{3}O_{12}-PVC composites were fabricated. Ceramics powders of bismuth titanate were prepared by the sol-gel method using bismuth nitrate pentahydrate Bi(NO_{3})_{3} \cdot 5H_{2}O and tetrabutyl titanate Ti(CH_{3}(CH_{2})_{3}O)_{4} as precursors.
