Studying The Effect of Annealing Temperature and Annealing Time on Physical Properties of Graphite


Graphite electrodes prepared by using carbon black as a filler material andphenolic resin as a binder. The samples treated thermally within temperature rangof 750-950)c for two and three hours . the variation in electrical resistivity andstructural properties as a function of the two variables were studied . electricalresistivity decreased with increasing treatment temperature and time. Increasingtemperature resulting in graphitization degree increasing ,also the inter atomicdistance comparing to the standard values decreased with increasing treatmenttemperature and time of treatment.
