The elimination of lead in piezoelectric applications remains challenging. Since the
advances in the piezoelectricity were found in the perovskite family in 2000, studies into lead …

We present a critical review that encompasses the fundamentals and state-of-the-art
knowledge of barium titanate-based piezoelectrics. First, the essential crystallography …

Piezoelectric materials are known to mankind for more than a century, with numerous
advancements made in both scientific understandings and practical applications. In the last …

High-performance piezoceramics are some of the most important and widely used materials,
and as such research into this topic is at the forefront of high-technology advanced …

After twenty years of partly quiet and ten years of partly enthusiastic research into lead-free
piezoceramics there are now clear prospects for transfer into applications in some areas …

Due to issues with Pb toxicity, there is an urgent need for high performance Pb-free
alternatives to Pb-based piezoelectric ceramics. Although pure BaTiO3 material exhibits …

Both low strain hysteresis and high piezoelectric performance are required for practical
applications in precisely controlled piezoelectric devices and systems. Unfortunately …

In this paper, two displacive phase transitions around the morphotropic phase boundary
(MPB) in Ba (Zr 0.2 Ti 0.8) O 3-x (Ba 0.7 Ca 0.3) TiO 3 (BZT-xBCT) ceramics were detected …

Abstract The Ba (Zr 0.2 Ti 0.8) O 3–x (Ba 0.7 Ca 0.3) TiO 3 system was synthesized in a wide
compositional range in order to study the relationship between its phase diagram and …

Lead free piezoelectric ceramics barium zirconate titanate–barium calcium titanate,[xBZT–
(1− x) BCT](0.48≤ x≤ 0.52), were synthesized by sol–gel method. Calcination of the as …
