Koke ya peteroli ifite graphite nyinshi ikoreshwa mu nganda zikora ibyuma bicukurwa mu buryo bwa ductile

Ibisobanuro bigufi:

Coke ya peteroli ifite graphite nyinshi kandi isukuye cyane ikorwa muri coke ya peteroli nziza cyane iri ku bushyuhe bwa 2,500-3,500°C. Nk'ibikoresho bya karuboni bifite imiterere isukuye cyane, ifite imiterere ya karuboni nyinshi idahinduka, sulfur nkeya, ivu rikeya, porosity nkeya n'ibindi.
