| Abstract Scope |
Directional tailoring of performance for oxide materials has been largely limited to taking advantage of anisotropies in single crystal materials. This presentation outlines the current status of process technology and scale up considerations for tailoring directionally oriented ceramic microstructures, with a focus on highly oriented ceramic piezoelectric materials primarily in the PMN-PZT family of materials. The engineering challenges associated with scaling each step of the manufacturing process to yield 150mm square by 10mm thick tiles will be outlined as will observations regarding process variability within a given tile and between multiple tiles from multiple powder lots. In addition, we will discuss modifications to these textured compositions and processes to control performance characteristics such as loss factor and coercive field. The electro-mechanical performance and performance trade-offs of materials for acoustic applications where power loss and self-heating are a significant issue will be the primary focus. |
