Dissertation completed in partial fulfillment of the requirements for the degree of Masters of Science in Materials Science and Engineering at the Kazuo Inamori School of Engineering, New York State College of Ceramics at Alfred UniversityCentrifugal bio-freeze casting, (CBFC), is a revolutionary new technique for the production of near net shape piezoelectric components. CBFC exploits the unique ability of Pseudomonas syringae bacteria to promote ice formation near 0°C. By combining water, bacteria and Pb(ZrxTi1-x)O3 in a centrifuge, it is possible to produce dense near net shape green bodies which later undergo vacuum-assisted dehydration and sintering. CBFC is an environmentally favorable process which avoids the use of binders to make complex piezoelectric components for a variety of applications. The economic viability and simplicity of CBFC makes it attractive on an industrial level.42 pagesen-USThesis
