Achieving Synergistic Enhancement of Piezoelectric Properties in KNN-based Ceramics
K sodium niobate(KNN)-based lead-free piezoelectric ceramics have become one of the most promising alternatives to lead-based piezoelectric ceramics due to their excellent piezoelectric properties, high Curie temperature, and simple preparation process. Piezoelectric ceramic devices such as ultrasonic transducers need to withstand large mechanical loads during operation, which can easily lead to microcracks and fracture failure … Read more
