Electrical Conductivity Of Aluminum Reinforced Graphite Electrodes
MetadataShow full item record
Composite, disc-like aluminum reinforced graphite electrodes were prepared, and an integrated parametric analysis has been performed to investigate the effect of some processing parameters on the electrical conductivity of the prepared samples. The presence of aluminum improved the electrical conductivity of graphite electrodes. A maximum in the electrical conductivity is always observed for samples baked at 600°C and/or for 1.5 hours baking time. The conductivity also increases with the compacting pressure. The novel idea of reinforcing graphite with metallic particulate fillers works well in improving the transport properties of graphite electrodes.
