Iinkcukacha eziphambili ze-graphite petroleum coke zezi zilandelayo: umxholo wokufuma ongaphantsi kwe-0.5%, isalfure engaphantsi kwe-0.05%, i-phosphorus ephakathi kwe-0.04-0.01, i-hydrogen nitrogen engaphantsi kwe-100%ppm. Umxholo ophezulu wekhabhoni wobukhulu bamasuntswana uphakathi, i-porosity iya kuba nkulu, isantya sokufunxa siyakhawuleza, kwaye ukwakheka kwayo kweekhemikhali kucocekile, izinga lokufunxa liya kuba phezulu. Ubungakanani bamasuntswana 0-5mm, 1-5mm, 0-10mm, njl.njl., bunokucutshungulwa ngokweemfuno zabathengi.
