The changes in the microstructure of activated carbon, after activation at three different temperatures (800 degrees C, 900 degrees C, 1000 degrees C) using different amounts of the activating agent, KOH (KOH/C ratio of 1: 1, 2: 1, 3: 1 and 4: 1), are studied using X-ray diffraction and Raman spectroscopy. The results showed the formation of localized nanographitic domains, along with the changes in the surface area and porosity of the activated carbon. The changes in the microstructure are found to be directly correlated with the magnetic properties and electrical conductivity. The interplay between ordering and disordering parameters in the activated carbon is found to determine the electrical conductivity and magnetic properties.1 aRaj, Kovummal, Govind1 aJoy, Pattayil, Alias  uhttps://library.ncl.res.in/content/role-localized-graphitization-electrical-and-magnetic-properties-activated-carbon
