Synthesis, Structural, and Electrical Properties of Pure PbTiO3 Ferroelectric Ceramics

Energy-storage properties and high-temperature dielectric relaxation behaviors of relaxor ferroelectric Pb(Mg1/3Nb2/3)O3–PbTiO3 ceramics

1 − x)Pb(Mg1/3Nb2/3)O3−xPbTiO3 (x = 0, 5, and 10 mol%) ceramics were prepared using a conventional mixed oxide solid state reaction method. The low-temperature relaxor behavior of (1 − x)Pb(Mg1/3Nb2/3)O3–xPbTiO3 ceramics were examined in the temperature range from 120 to 523 K. A broad dielectric maximum that shifted to higher temperatures with increasing frequency, signified the relaxor-type b...

Synthesis and Processing of Ferroelectric Pzt Powders, Ceramics and Films

In this chapter, various synthesis routes for PZT powders and fabrication processing techniques for PZT ceramics and films are reviewed. Emphasis is placed on chemical routes, especially the hydrothermal synthesis of PZT powders. The principles of the colloidal chemistry in ceramic suspension and its application to the colloidal processing of ceramics and films, especially when using sub-micron...

Structural, magnetic and electrical properties of pure and Dy-doped Fe2O3 nanostructures synthesized using chemical thermal decomposition technique

Pure (S1) and Dy3+-doped α-Fe2O3 (S2 and S3) nanoparticles were prepared by a combustion synthesis method at 700 ºC for 8 h using Fe(acac)3 (Tris(acetylacetonato)Iron(III)) as raw material. Characterizations of the prepared powders were carried out by powder X-ray diffraction (PXRD). Structural analysis was performed b...
