Summary

Aqueous colloidal processing of nanosized and submicron ceramic particles by means of electrophoretic deposition is considered a new process for manufacturing multifunctional electroceramics. Electrophoretic shaping process emphasizes the integration of colloidal particles into multifunctional structures and the production of novel architectures at finer scales in monolithic, composite and thick film form. Designing of advanced monolithic ceramics, layers and composites by electrophoretic deposition includes research of interaction between ceramic particles, organic and/or inorganic dopants and substrate surfaces influenced by external electrical fields.

This work represents a brief summary of our continuous research on electrophoretic processing of multifunctional electroceramic materials. It focuses on tailoring electrochemical and dielectrical properties of functionally graded mixed ionic-electronic conductors and ceramic piezoelectrics for use as sensors and actuators. Based on impedance measurements and transmission electron microscopy analysis qualitative and quantitative microstructure-property relations for both application fields are given. Prospective applications of EPD processing methods are derived, by comparing these results with mixed ionic-electronic conductors and xPbZrO3-(1-x)PbTiO3 (0 < x < i) binary system characteristics given in the state of the art.
