Porous textured ceramics with controlled grain size and orientation

Texture in dense or porous ceramics can enhance their functional and structural properties. Current methods for texturation employ anisotropic particles as starting powders processes that drive orientation into specific directions. Using ultra-low magnetic fields combined with slip casting, it is possible to purposely orient magnetically responsive any direction. When those are suspended nanoparticles, templated grain growth occurs during sintering yield a textured ceramic. Yet, the final grains usually micrometric, leading weak mechanical Here, we explore how tune size using casting growth. Our strategy consists changing of ensuring alignment densification occurs. The obtained featured large range anisotropy, submicrometric thickness Textured tunable dimensions porosity promising filtering, biomedical composite applications.
