Lead-Free Piezoelectrics

Covering a key contemporary issue in the piezoelectrics ceramics industry, this volume is a comprehensive overview of current research into materials and products that contain alternatives to lead, the use of which is becoming ever more restricted.

Ecological restrictions in many parts of the world are demanding the elimination of Pb from all consumer items. At this moment in the piezoelectric ceramics industry, there is no issue of more importance than the transition to lead-free materials. The goal of Lead-Free Piezoelectrics is to provide a comprehensive overview of the fundamentals and developments in the field of lead-free materials and products to leading researchers in the world. The text presents chapters on demonstrated applications of the lead-free materials, which will allow readers to conceptualize the present possibilities and will be useful for both students and professionals conducting research on ferroelectrics, piezoelectrics, smart materials, lead-free materials, and a variety of applications including sensors, actuators, ultrasonic transducers and energy harvesters.

Provides information on all the important families of materials that are being considered as viable candidate for lead-free piezoelectrics Covers in-depth material properties of most promising compositions illustrating the effect of dopants, domain engineering, texturing, and microstructure Serves as the foundation for transitioning the lead-free materials into consumer electronics
