Description
Summary:Na 2 O-CoO-P 2 O 5 materials were synthesized by soft hydrothermal technique at relatively low temperature and pressure conditions. These materials have shown positive correlation of crystallanity, size, thermal stability, magnetic properties and ionic conductivity with the concentration of Cobalt ions. Microstructures of the nano crystals were identified by taking the Scanning Electron Microscopy pictures. Thermal properties and minute structural variations of the prepared materials were investigated by DTA and FTIR studies. Magnetic results have revealed that these are frequency dependent prospective paramagnetic materials. A preliminary impedance analysis result indicates these are prospective solid electrolyte materials.
