| Summary: | 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. |
