Microstructure design and multifunctionality of barium zirconate titanate-barium calcium titanate thin films prepared by chemical solution deposition
Barium zirconate titanate-barium calcium titanate 0.5Ba(Zr0.2Ti0.8)O3-0.5(Ba0.7Ca0.3)TiO3 (BZT-BCT) ceramic exhibits a high piezoelectric response in the vicinity of room temperature. It is an environment-friendly alternative to Pb(Zr1-xTix)O3 (PZT), the most used ceramic material in piezoelectric applications. Thin films meet the requirements related to the miniaturization of electronic components such as in …
Microstructure development in lithium lanthanum titanate solid electrolyte
All-solid-state batteries are one of the key technologies for future energy storage and the transition to a climate-neutral society. They offer improved safety, stability, and a broader operating temperature range compared to conventional batteries with liquid electrolyte. Perovskite Li0.33La0.56 0.11TiO3 (LLTO) is recognized as one of the most promising solid …
Mechanisms and Effect of Deep Cryogenic Treatment on Steel Properties
Deep cryogenic treatment (DCT) is a type of cryogenic treatment, during which a material is subjected to temperatures below −160 °C. When a metallic material is modified with DCT, changes occur down to the nanoscopic level. DCT induces microstructural changes such as grain size refinement, formation of new grains, movement …
Structural and electrical properties of 0.65PMN-0.35PT thick films on different substrates
A starting powder with the nominal composition 0.65Pb(Mg1/3Nb2/3)O3–0.35PbTiO3 (0.65PMN–0.35PT), which corresponds to the morphotropic phase boundary (MPB) composition, was prepared by mechanochemical activation followed by attritor milling and low-temperature calcination at 700°C. It had a narrow particle size distribution with the median particle size equal to 0.3 μm. From the …
