Abstract
In the present work, a Frenkel cationic conductor Ba(NO3)2 was dispersed with chemically inert oxide ZrO2 (<100nm in size) using mechanical mixing for an hour in the presence of acetone and it is done for different m/o of ZrO2 (5,10,15,20 and 25m/o). The pellets were prepared at a pressure of 4 tones/cm2 and sintered at 400oc for 12 hr. The characterizations of these samples were done through XRD, TG- DTA, SEM, EDAX and FTIR. X-Ray Diffractograms, TG- DTA and FT-IR spectrum revealed that there was neither formation of solid solution between host and dispersoid nor a new phase. Scanning Electron Micrographs have shown uniform distribution of dispersoid in the host material and also agglomerations of dispersoid particles at higher m/o of ZrO2. FT-IR spectroscopy gave evidence for the existence of OH-1(hydroxyl group) ion in pure ZrO2 and dispersed samples. EDAX confirmed the presence of Ba, N,O,Zr atoms in all the dispersed solid electrolyte system (1-x) Ba(NO3)2: x ZrO2.
