I-graphite plate (isikebhe se-graphite) sisebenzisa impahla esezingeni eliphakeme ye-graphite, ifaka i-organic organic enokumelana okuqinile kwe-acid. It is refined by high-pressure ukwakha, ukukhulelwa kwe-vacuum, kanye nokwelashwa okushisa okuphezulu. Inokumelana okungajwayelekile kwe-asidi nokushisa. Kuyinto enhle yokufaka ulwelwesi lwamathangi okuphendula i-phosphoric acid kanye namathangi wokugcina i-phosphoric acid embonini yamakhemikhali. Umkhiqizo unezici zokumelana nokugqoka, ukumelana namazinga okushisa, ukumelana nengcindezi, ukumelana nokugqwala, ukumelana okungangena, uwoyela-wamahhala wokuzithambisa, i-coefficient encane yokwandisa, nokusebenza okuphezulu kokufaka uphawu.
