Electrophoretic Deposition (EPD) process is a fabrication technique that has received huge attention in the recent years. The EPD process requires relatively short processing time and simple set-up and allows the forming of both thick and thin ceramic components economically. Although EPD has many advantages over the other methods of forming ceramic films, the process is not fully established in both experimental and theoretical aspects. As EPD is basically a colloidal process, a thorough understanding on the colloidal stability of the suspension is necessary. In this project, focus was placed on the study of colloidal theory and the EPD forming process of an advanced functional ceramics, Lead Zirconate Titanate (PZT). In the first part of this report, the synthesis of the PZT powders was discussed. Next, in the second part, the EPD studies were carried out. Theoretical relationships were examined and validated using experimental results obtained.
