Coke ya peteroli ifite graphite nyinshi (GPC) ikozwe muri coke ya peteroli nziza cyane munsi y'ubushyuhe bwa 2,500-3,500°C. Nk'ibikoresho bya karuboni bifite imiterere ya karuboni nyinshi, ifite imiterere ya karuboni nyinshi, sulfur nkeya, ivu rikeya, porosity nkeya n'ibindi. Ishobora gukoreshwa nk'umurinzi wa karuboni (Recarburizer) kugira ngo ikore icyuma cyiza, icyuma gikozwe mu ibumba n'ibumba. Ishobora kandi gukoreshwa muri pulasitiki na rubber nk'inyongeramusaruro.
