Description
Summary:Directional tailoring of performance for ceramic materials has been largely limited to taking advantage of anisotropies in single crystal or composite materials. This presentation outlines the process technology and scale up considerations for tailoring directionally oriented ceramic microstructures, with a focus on achieving near single crystal performance from highly oriented ceramic piezoelectric materials in the PIN-PMN-PT, and PMN-PZT families of materials. The engineering challenges associated with scaling each step of the manufacturing process for both tape cast approaches and additive manufacturing approaches will be outlined as will observations regarding process variability. 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 will be discussed.
