Soo saaraha batroolka kookaha (GPC).

Graphite petroleum coke waxaa si weyn loogu isticmaalaa sidii kor u qaadida kaarboon ee samaynta birta iyo warshadaha tuurista saxda ah, sida beeralayda warshadaha aasaasiga ah, sida wakiilka dhimaya ee warshadaha biraha iyo sida walxaha refractory. Graphite petroleum coke waxay kor u qaadi kartaa nukleation of graphite ee xalka birta, kordhinta qadarka birta ductile iyo hagaajinta ururka iyo darajada birta cawl. Iyada oo loo marayo indho-indheynta qaab-dhismeedka yar-yar, kookaha batroolka graphite wuxuu leeyahay sifooyinka soo socda: Marka hore, maadada ferrite ee birta ductile si weyn ayaa loo kordhin karaa iyada oo aan la isticmaalin stabilizers pearlite; Marka labaad, saamiga V-qaabeeya iyo garaafyada VI-qaabeeya waa la kordhin karaa inta lagu jiro isticmaalka; Saddexaad, marka la barbar dhigo hagaajinta qaabka khad nodular ah, korodhka la taaban karo ee qadarka khad nodular-ku wuxuu yarayn karaa isticmaalka walxaha qaaliga ah ee nukliyeerka ah ee hadhow hagaajinta, taasoo keentay kayd qiimo badan.
