Templated grain growth of Bi(Zn0.5Zr0.5)O3 modified BiScO3−PbTiO3 piezoelectric ceramics for high temperature applications

open access: yesJournal of Asian Ceramic Societies, 2021
2.5Bi(Zn0.5Zr0.5)O3−37.5BiScO3−60PbTiO3 (BZZ-BS-PT) ceramics were successfully textured in the [001] by templated grain growth (TGG) process using 5 vol% -oriented BaTiO3 (BT) plate-like templates. The templates were aligned in the matrix powder via tape

Temperature-insensitive KNN-based ceramics by elevating O-T phase transition temperature and crystal texture

open access: yesJournal of Materiomics, 2023
The inferior temperature stability of piezoelectric response is the main drawback of KNN-based ceramics. Here, the Ba-doped 0.97(K0.48Na0.52)(Nb0.96Sb0.04)O3-0.03Bax(Bi0.5Ag0.5)1-xZrO3 (abbreviated as KNNS-BxBAZ) textured ceramics were prepared by the ...

Textures in Ceramics [PDF]

open access: yesTexture, Stress, and Microstructure, 1995
The texture is defined as the orientation distribution of the crystallites in a polycrystalline material. This definition is the same for all kinds of materials. Also the motivation for texture studies is the same in all materials i.e. the formation of textures by anisotropic solid state process and the influence of textures on anisotropic physical or ...

Residual stress relaxation and microstructure in ZnO thin films [PDF]

open access: yes, 2006
Stability under normal environmental conditions over a long period of time is crucial for sustainable thin-film device performance. Pure ZnO films with thicknesses in the 140 - 450 nm range were deposited on amorphous glass microscope slides and (100 ...

Laser surface texturing of a WC-CoNi cemented carbide grade: surface topography design for honing application [PDF]

open access: yes, 2018
Abrasive effectiveness of composite-like honing stones is related to the intrinsic surface topography resulting from the cubic boron nitride (CBN) grains protruding out of the metallic matrix.

Preparation and anisotropic properties of textured structural ceramics: A review

open access: yesJournal of Advanced Ceramics, 2019
Ceramics are usually composed of randomly oriented grains and intergranular phases, so their properties are the statistical average along each direction and show isotropy corresponding to the uniform microstructures.
