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 recent review for the Restriction of Hazardous Substances Directive (RoHS) by the
expert committee, appointed by the European Union, stated that the replacement of PZT “ …

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 …

The ban of lead in many electronic products and the expectation that, sooner or later, this
ban will include the currently exempt piezoelectric ceramics based on Lead-Zirconate …

The weld reinforcement has a strong impact on mechanical properties of MIG welded joints.
This paper investigates the effect of weld reinforcement on tensile, high cycle fatigue and …

A considerable body of knowledge now exists from studies involving the development of
lead‐free piezoelectric ceramics and a number of high potential alternatives to current lead …

Fatigue in ferroelectric ceramics is the gradual change of material properties with cyclic
loading. It is caused by microscopic material modifications of mechanical or electrical origin …

The newly developed spherical smart aggregate (SSA) based on a radially polarized
spherical piezoceramic shell element has unique omnidirectional actuating and sensing …

Causes of breakdown, both mechanical and electrical, in high voltage, high energy density,
BaTiO 3 capacitors were studied. The flexural strength of the capacitors was 96 MPa. Failure …

Fatigue in ferroelectric ceramics is the result of an intricate interplay of electrical, mechanical
and electrochemical processes, each of which has been claimed responsible for fatigue. We …
