With restrictions on hazardous substance usage in various applications comes lead-free compositions in certain piezoceramic applications. The current knowledge of primary piezoelectric properties has reached a sufficient level for use in applications, but research efforts continue toward a better understanding of secondary properties. Efforts to reduce the production and waste disposal of toxic lead has resulted in open avenues for new materials with properties better than lead zirconate titanate.

The August, 2018 issue of MRS Bulletin focused on ​Lead-free Piezoceramics, and this webinar builds on the information presented in the issue.  Attendees were able to participate in a live Q&A session with the speakers at the conclusion of each talk.
