Structural phase transitions of PbZr0.52Ti0.48O3 ceramic: An infrared spectroscopy study
(Taylor & Francis Ltd, 2006-01-01)
The recent discovery of a ferroelectric monoclinic phase in the PbZr1-xTixO3 (PZT) system attained the attention of several researchers due to the possibility of understanding the relationships between structural features ...
The Aerosol OT + n-butanol + n-heptane + water system: Phase behavior, structure characterization, and application to Pt70Fe30 nanoparticle Synthesis
(Amer Chemical Soc, 2007-10-23)
A phase diagram of the pseudo-ternary Aerosol OT (AOT) + n-butanol/n-heptane/water system, at a mass ratio of AOT/n-butanol = 2, is presented. Conductivity measurements showed that within the vast one-phase microemulsion ...
Pressure-induced phase transitions in Zr-rich PbZr1-xTixO3 ceramics
(2001-08-20)
A Raman study of structural changes in the Zr-rich PbZr1-x TixO3 (PZT) system under hydrostatic pressures up to 5.0 GPa is presented. We observe that externally applied pressure induces several phase transitions in PZT ...

Structural characterization of phase transition of Al2O3 nanopowders obtained by polymeric precursor method
(Elsevier B.V., 2007-06-15)
Nanocrystalline Al(2)O(3)powders have been synthesized by the polymeric precursor method. A study of the evolution of crystalline phases of obtained powders was accomplished through X-ray diffraction, micro-Raman spectroscopy ...

Metal-insulator transition in Nd1-xEuxNiO 3 compounds
(2006-07-05)
Polycrystalline Nd1-xEuxNiO3 (0≤x≤0.5) compounds were synthesized in order to investigate the character of the metal-insulator (MI) phase transition in this series. Samples were prepared through the sol-gel route and ...
