“…8,9,[15][16][17][18] Time-of-flight (TOF) neutron scattering data were collected on powdered samples on the Nanoscale Ordered Materials Diffractometer (NOMAD) at the Spallation Neutron Source (SNS) located at Oak Ridge National Laboratory (ORNL) with a collection time between 2 h to 4 h per sample. 23 Samples were loaded in a fused silica capillary, and an empty capillary was collected and subtracted as background.…”

“…These compounds have been previously characterized from the viewpoint of their dielectric properties, Raman spectroscopy, average x-ray structure, and electron microscopy. 8,9,[15][16][17][18] Some of the key findings that emerge include that despite the small substitution levels, the Sn 2+ lone pairs drive the local ordering behavior. The local structure of both compounds more closely follow the behavior of PbTiO 3 than that of the parent compounds SrTiO 3 and BaTiO 3 , respectively.…”

Average and local structure of the Pb-free ferroelectric perovskites (Sr,Sn)TiO3 and (Ba,Ca,Sn)TiO3 The characteristic structural off-centering of Pb 2+ in oxides, associated with its 6s 2 lone pair, allows it to play a dominant role in polar materials, and makes it a somewhat ubiquitous component of ferroelectrics. In this work, we examine the compounds Sr0.9Sn0.1TiO3 and Ba0.79Ca0.16Sn0.05TiO3 using neutron total scattering techniques with data acquired at different temperatures. In these compounds, previously reported as ferroelectrics, Sn 2+ appears to display some of the characteristics of Pb 2+ . We compare the local and long-range structures of the Sn 2+ -substituted compositions to the unsubstituted parent compounds SrTiO3 and BaTiO3. We find that even at these small substitution levels, the Sn 2+ lone pairs drive the local ordering behavior, with the local structure of both compounds more similar to the structure of PbTiO3 rather than the parent compounds.

“…So far, chemical modifications and a controlled microstructure led to a maximum ~ 160 °C on this family of materials. [266][267][268][269] In the search for new lead-free piezoceramics, an attempt was made to look for a cation comparable to Pb 2+ . The cation Bi 3+ was discussed as a candidate due to similar ionic radii and inertpair 6s 2 electrons as in Pb 2+ .…”

“…It has been reported that the Curie temperature of (Ba,Ca)TiO 3 ceramics can be increased by doping Sn 2+ in the A-site of perovskite structures by calcining and sintering in a reducing atmosphere [64,65,66,67]. We investigated the Curie temperature and piezoelectric properties of Sn 2+ -doped KNN-based ceramics that were calcined and sintered in a reducing atmosphere [60].…”

Although lead-free piezoelectric ceramics have been extensively studied, many problems must still be overcome before they are suitable for practical use. One of the main problems is fabricating a multilayer structure, and one solution attracting growing interest is the use of lead-free multilayer piezoelectric ceramics. The paper reviews work that has been done by the authors on lead-free alkali niobate-based multilayer piezoelectric ceramics co-fired with nickel inner electrodes. Nickel inner electrodes have many advantages, such as high electromigration resistance, high interfacial strength with ceramics, and greater cost effectiveness than silver palladium inner electrodes. However, widely used lead zirconate titanate-based ceramics cannot be co-fired with nickel inner electrodes, and silver palladium inner electrodes are usually used for lead zirconate titanate-based piezoelectric ceramics. A possible alternative is lead-free ceramics co-fired with nickel inner electrodes. We have thus been developing lead-free alkali niobate-based multilayer ceramics co-fired with nickel inner electrodes. The normalized electric-field-induced thickness strain (Smax/Emax) of a representative alkali niobate-based multilayer ceramic structure with nickel inner electrodes was 360 pm/V, where Smax denotes the maximum strain and Emax denotes the maximum electric field. This value is about half that for the lead zirconate titanate-based ceramics that are widely used. However, a comparable value can be obtained by stacking more ceramic layers with smaller thicknesses. In the paper, the compositional design and process used to co-fire lead-free ceramics with nickel inner electrodes are introduced, and their piezoelectric properties and reliabilities are shown. Recent advances are introduced, and future development is discussed.
