Makhalidwe a calcined petroleum coke ndi carbon yambiri, low volatility content, high density and intensity. calcined petroleum coke ingagwiritsidwe ntchito ngati zopangira kapena zowonjezera popanga carbon black, zomwe zimakhudza magwiridwe antchito ndi ubwino wa carbon black, yomwe imagwiritsidwa ntchito mu rabara, inki, zokutira ndi mafakitale ena. Mu gawo la mphamvu zatsopano monga ma fuel cell, ingagwiritsidwe ntchito ngati zopangira zopangira ma electrode, ndipo pambuyo pochizidwa ndi kukonzedwa kwapadera, ingagwiritsidwe ntchito kukonzekera ma electrode okhala ndi ma conductivity abwino amagetsi komanso mphamvu zothandizira kukula kwa ma fuel cell.
