Toward lead-free piezoelectrics: KNN-based ceramic demonstrates enhanced electrical properties thanks to two-step sintering process

By Lisa McDonald / January 6, 2023

Awareness of lead’s toxicity drives research on alternative lead-free piezoelectric materials. But traditional high-temperature sintering processes can inadvertently deteriorate a lead-free ceramic’s piezoelectric response. A two-step sintering process can minimize this deterioration, and researchers in China identified the optimum temperature and dwell time for the first step.
