Additive manufacturing of textured ceramics

The Journal of the Acoustical Society of America, 2021
The study of tailoring crystallographic gain orientation has been an area of great interest due to the ability to enhance specific material properties. Bulk textured ceramics are commonly manufactured by aligning seed grains in a polycrystalline material through tape casting.

Additive manufacturing of highly textured alumina ceramics

Open Ceramics, 2021
In this work we demonstrate the feasibility of fabricating textured alumina employing a lithography-based ceramic manufacturing process. The combination of vat rotation and platform immersion contributes to the alignment of alumina templates during ...

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

Journal 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

High-throughput synthesis of thermoelectric Ca$_3$Co$_4$O$_9$ films [PDF]

, 2013
Properties of complex oxide thin films can be tuned over a range of values as a function of mismatch, composition, orientation, and structure. Here, we report a strategy for growing structured epitaxial thermoelectric thin films leading to improved ...

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

, 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 ...

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

Journal 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]

Texture, 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 ...
