Ba(Ti1−xSnx)O3 (x=0.13) nanomaterials produced by low-temperature aqueous synthesis

Enhanced near-ambient temperature energy storage and electrocaloric effect in the lead-free BaTi0.89Sn0.11O3 ceramic synthesized by sol–gel method

“…However, despite their high dielectric constant, sharp dielectric peaks were observed. The relaxation degree γ of our ceramic reached 1.428 which shows a rather broad (diffuse) dielectric constant peak compared to 1.34 reported by Merselmiz et al reported important γ values of 1.536, 1.44 and 1.5 for a BTS13, BTS5 and BTS10 respectively but the dielectric constants were relatively low [23], [30], [34]. Hence, the enhanced dielectric properties found in our BTS11 ceramic synthesized by a sol-gel process is mainly due to the quasi quadruple point where all phases coexist.…”

Defect mediated mechanism in undoped, Cu and Zn-doped TiO2 nanocrystals for tailoring the band gap and magnetic properties

“…The band centered at nearly 550 cm À1 are due to bonding among metal and oxygen, i.e., metal-oxygen bonds of (Ti-O) in undoped, (Ti-O, Cu-O) and (Ti-O, Zn-O) in Cu and Zn doped TiO 2 nanocrystals. 55,56 Furthermore, no peak corresponding to any other oxide phases of doped elements appeared in the spectra. It reveals that doped metal ions are introduced into the Ti framework.…”

Influence of Zirconium (Zr4+) Substitution on the Crystal Structure and Optical and Dielectric Properties of Sr0.8Mg0.2(Sn1–xZrx)O3 Ceramics

“…However, the temperatures needed for these two alternate methods are 800 or 1000 °C, respectively. Low-temperature and quick synthesis methods are uncommon even with the numerous processes and characterizations of strontium stannate (SrSnO 3 ) that have been frequently investigated in the literature. − Long synthesis times are a feature of all of the ceramic routes for the stannates mentioned above (up to 16 h). As a result, it is clear that a more cost-effective, shorter-cycle, and lower-temperature synthesis process is required.…”
