Textured Piezoelectric Ceramics - Relationship between Processing and Properties

Main Content

Textured piezoelectric ceramics bridge the gap between traditional polycrystalline ceramics, such as PZT, and single crystal materials. Created by adding seed crystals to the ceramic powder slurry, textured piezoceramics can approach the high piezoelectric performance of single crystals at a considerably lower cost, making them desirable in many applications. In this webinar, we will discuss the connections between processing, preferred microstructure alignment and the electro-mechanical properties of the end material, focusing mainly on the Mn-doped PMN-PZT material family. The engineering challenges associated with each step of the manufacturing process to yield tailored properties will be outlined and linked to the ability to control the process in a repeatable fashion. We will discuss performance parameter and material trade-offs for both transmit and receive applications. Presenters: Dr. Mark Fanton, Research Associate Professor at Penn State University. Dr. Gerald Stranford, Senior Engineering Manager at CTS Corporation.
