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 …

The field of lead-free piezoceramics, which aims to replace lead zirconate titanate (PZT) and
related perovskite materials, has been vibrant for almost 15 years. Once the science in this …

Piezoelectric materials convert mechanical energy into electric energy, and vice versa. They
have been applied in many critical fields, such as motor vehicles, medical devices, the …

The electrostrictive effect has some advantages over the piezoelectric effect, including
temperature stability and hysteresis-free character. In the present work, we report the diffuse …

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 …

There is great interest in lead-free (B a 0.85 C a 0.15)(T i 0.90 Z r 0.10) O 3 (15/10BCTZ)
because of its exceptionally large piezoelectric response [Liu and Ren, Phys. Rev. Lett. 103 …

High-performance lead-free piezoelectric materials have become a hot topic in the field of
advanced functional materials. In 2009, the (1− x) Ba (Zr0. 2Ti0. 8) O3–x (Ba0. 7Ca0. 3) TiO3 …

In the present work, various grain size phenomena were studied in promising lead-free
piezoelectric ceramics (Ba 0.85 Ca 0.15)(Zr 0.10 Ti 0.90) O 3 fabricated via chemical and …

The search for electroceramic materials with enhanced ferro-pyro-piezoelectric properties
and revealing the perovskite type structure has been the objective of a significant number of …
