Due to ever-increasing environmental concerns, lead-free piezoceramics have been studied
for more than half a century with the purpose of replacing toxic lead-based counterparts. A …

The similar electronic structure of Bi 3+ and Pb 2+ has motivated researchers to explore
bismuth-based perovskite compounds, which in the past decade has been further fuelled by …

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 …

The present work demonstrates the effect of the grain size on electrocaloric and pyroelectric
properties in BaTiO 3-based ceramics prepared by a chemical coating method and then …

3-xBi 0.5 Na 0· 41 K 0· 09 ZrO 3 (x= 0.05) ceramics annealed in air, oxygen, and argon …

In this work, we have prepared some doped BaTiO 3 powders with the aim to study the
change of physical properties and some behaviors to be closely sensitive to the nature of the …

Na1/2Bi1/2TiO3-based materials have gained considerable attention for their potential to
exhibit giant strain, very-high ionic conductivity comparable to yttria stabilized zirconia or …

This study was designed to better understand the microstructural and phase evolution of
lead-free sodium potassium niobate based piezoceramics with a nominal composition (K 0.5 …

Abstract Na 1/2 Bi 1/2 TiO 3-based materials exhibit potential for applications in high-power
ultrasonics. The composites of Na 1/2 Bi 1/2 TiO 3-yBaTiO 3 (NBTyBT; y denotes mole%) …

Crack opening displacements were evaluated on semi‐elliptical indentation cracks in lead‐
free (1− x)(Na1/2Bi1/2) TiO3–xBaTiO 3 piezoceramics and a commercially available PZT …
