Research ArticleOpen accessPhrase in the titleElectrical Properties of Cobalt Oxide/Silica Nanocomposites Obtained by Sol-Gel TechniqueGomaa A.M. Ali, Osama A. Fouad, Salah A. MakhloufThis work is an extension of our previous studies on cobalt oxide nanoparticles impeded in a silica matrix. Here we study the preparation and characterization of high cobalt content materials (60-90 wt%). In addition, the DC electrical conductivity of the prepared materials in a wide temperature range (350-673 K) was measured and discussed. The activation energy has been obtained according … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 1 · 18 Nov 2015 · 8,678 accessesView PDF Cite
