Nanocrystalline zirconia based powders synthesized by hydrothermal method

Structure and Morphology of Nanocrystalline BZT Powders Prepared Using Hydrothermal Method

The nanocrystalline of BaZrxTi1-xO3 (BZT) (where x= 0, 0.001 and 0.008) powders have been prepared by hydrothermal method at 150 o C for 2h using as prepared titanium tetraclouride, zirconium oxyclouride and barium hydroxide as starting materials. They were investigated by x-ray diffraction XRD, transmission electron microscopy TEM, selection area electron diffraction SAED and high resolution t...

Detection of tetragonal zirconia in alumina–zirconia powders by thermoluminescence

The thermoluminescence (TL) after excitation by UV or X-rays radiation of alumina-zirconia powders is investigated. The composites present five of the characteristic peaks of zirconia at −170, −145, −90, 0 and 95 °C. After a thermal treatment of mixed oxides, a new peak is observed at −35 °C in TL. This peak reveals the presence of stabilized tetragonal zirconia in the material. Moreover by com...

Piezoelectric Materials Synthesized by the Hydrothermal Method and Their Applications

Synthesis by the hydrothermal method has various advantages, including low reaction temperature, three-dimensional substrate availability, and automatic polarization alignment during the process. In this review, powder synthesis, the fabrication of piezoelectric thin films, and their applications are introduced. A polycrystalline lead zirconate titanate (PZT) thin film was applied to a micro ul...

Characteristics of BNT films synthesized by a hydrothermal method

Metallic copper nanostructures synthesized by a facile hydrothermal method.

A facile hydrothermal route has been developed for the synthesis of nearly spherical copper nanoparticles, copper nanocubes and ribbon-like network nanostructures. The as-prepared copper nanostructures were characterized by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), transmission electron microscopy (TEM), high-resolution TEM (HRTEM), and...
