Influence of selected coal contaminants on graphitic

Influence of selected coal contaminants on graphitic carbon electro-oxidation for appliion to the direct carbon fuel cell. cold setting, epoxy resin. The sample was then ground using various grades of silicon carbide paper on a rotating turn-table and finally polished using diamond and silica compounds. This resulted in a relatively flat
