Traditional vs. non-traditional materials for carbon paste electrode preparation: on relation between the composition and properties

Abstract

Several new types of carbon pastes were prepared as well as pastes made from various abrasive materials, examined and characterized. The main attention has been paid to the changes in their ohmic resistance, relative to the dependence on the composition of powder material to paraffin oil as pasting liquid. The results were compared with those of “traditional” carbon paste electrodes based on graphite powder and the differences in physical as well as electrochemical properties were discussed and explained. As found, the most evident difference was in the optimal carbon-to-binder ratio of the paste.
