Silver(II) oxide (AgO), an active material for batteries, wits synthesized by oxidation of silver(I) nitrate in alkaline medium and was characterized using various physico-chemical techniques for trace metal impurities, structure and thermal stabilities and various physical parameters. The results of analytical analyses involving x-ray fluorescence, atomic absorption and emission spectrometries reveal that the synthesized AgO has the purity >98% and contain Na, Fe, Ca, Cu, Mg Zn, Si Al, B etc. as traces. The structural and thermal investigations show that AgO has monoclinic structure and is stable upto 130 degreesC, beyond that AgO decomposes into two stages; the first stage corresponds to the conversion of AgO to Ag2O while the second stage is the indicative of Ag2O to Ag conversion The determined values of densities lie in the order of bulk density < tap density < true density, having surface area 0.307 m(2)/g average particle size 20.73 micron pore volume 0.235 cm(3)/g and porosity 57%.
