Rapid synthesis of LiCr0.15Mn1.85O4 by glycine-nitrate method
(Solid State Ionics, 2006)
LiCr0.15Mn1.85O4 spinel has been successfully synthesized by glycine-nitrate method (GNM). The presence of pure spinel phase was confirmed by long term XRPD measurements and the Rietveld structural refinement. Lattice ...
Dielectric relaxation and conductivity in barium salt of 12-tungstophosphoric acid hydrate
(Solid State Ionics, 2002)
Barium salt of 12-tungstophosphoric acid (WPA) hydrate BaHPW12O40.7H(2)O (BaHWPA-7H20) has been investigated both in the microwave (X-band) region and in the lower frequency (5 Hz-500 kHz) region. This work is a continuation ...
Structural modifications of dodecatungstophosphoric acid hexahydrate induced by temperature in the 10-358 K range. In situ high-resolution neutron powder diffraction investigation
(Solid State Ionics, 2002)
Dodecatungstophosphoric acid hexahydrate H3PW12O40.6H(2)O crystal structure has been investigated by neutron powder diffraction (NPD) at different temperatures in the 10-358 K range. A nonconvergent reversible phase ...
Thermodynamic modeling of the cerium-yttrium-oxygen system
(Solid State Ionics, 2008)
The published data for the thermochemical properties and phase relationships of the cerium-yttrium-oxygen system have been critically examined. The thermodynamic properties of the phases are described using compound energy ...
The influence of monovalent and bivalent cations on the electrical properties of 12-Tungstophosphoric acid salts
(Solid State Ionics, 2005)
The effect of monovalent and bivalent cations on some electrical properties of 12-tungstophosphoric acid (WPA) salts were studied. The charge carriers in this acid are protonic entities such as H+, OH- and various forms ...
Heteropoly compounds - From proton conductors to biomedical agents
(Solid State Ionics, 2005)
Heteropoly compounds (HPCs) have been a matter of interest in basic and applied science for more than a century. From their first synthesis, many advances have been made to promote the use of HPCs in different ways in ...
Nanostructured phosphorous tungsten bronzes from ultrasonic spray pyrolysis
(Solid State Ionics, 2005)
