High‐entropy strategy is a design that uses multiple elements to increase configurational
entropy. As an emerging research field, high‐entropy was originally applied to metals, but it …

In the present work, the nature of phase evolution of (1− x)(Na 0.5 Bi 0.5) TiO 3-xSrTiO 3
(NBT-xST) solid solutions with x of 0–0.6 is revealed by characterizing the dielectric and …

Piezoelectric materials transform electrical energy to mechanical energy and vice-versa
making them technologically important as actuators, sensors and transducers in wide …

For the development of lead-free Bi 0.5 Na 0.5 TiO 3 prototype materials, it seems conflicting
to improve the piezoelectric response (d 33) and depolarization temperature (T d) …

Influence of Bi-non-stoichiometry is studied on the dielectric and ferroelectric properties of
0.72 Bi 0.5+ x Na 0.5 TiO 3-0.22 SrTi 0.875 Nb 0.1 O 3-0.06 BaTiO 3 (BNBSNT) lead-free …

Abstract Na 0.5 Bi 0.5 TiO 3-BaTiO 3 (NBT-BT)-based lead-free piezoelectric ceramics have
been actively studied in recent years as a potential replacement for lead-based materials in …

Driven by environmental concerns and governmental directives, a sustained research effort
in the last decade and half has led to the development of lead-free alternatives which can …

Abstract Na1/2Bi1/2TiO3 (NBT) based ceramics are amongst the most promising lead‐free
ferroelectric materials. It was expected that the defect chemistry and the effect of doping of …

The designed defect-engineering has been proved to be an effective way to promote
properties in potassium sodium niobate (KNN)-based ceramics. Here, we focus on the …

Abstract Na 0.5 Bi 0.5 TiO 3 (NBT)-based compositions are among the most promising lead-
free ferroelectrics. Although studies of modification of NBT-based compositions' properties …
