Inkcazo emfutshane:

I-Needle coke luhlobo olukumgangatho ophezulu oluye lwaphuhliswa ngamandla kwizinto zekhabhoni. Inkangeleko yayo iqinile njengesilivere-grey enemingxuma ene-metallic luster. Xa ithelekiswa necala elifana nefayibha okanye i-needle-like texture, inomvakalelo wokuthambisa. Yinto esetyenziswa ekuveliseni iimveliso zekhabhoni eziphezulu ezifana nezixhobo zekhabhoni ezikhethekileyo ze-electrode ephezulu, iifayibha zekhabhoni kunye nezinto ezidityanisiweyo. Ngokwezinto ezahlukeneyo zemveliso, i-needle coke inokwahlulwa ibe yi-Needle coke yi-needle coke esekelwe kwi-oyile kunye ne-needle coke esekelwe kumalahle. I-needle coke eveliswa kwi-petroleum residue njengezinto eziluhlaza yi-needle coke esekelwe kwi-oyile; i-needle coke eveliswa kwi-coal tar pitch kwaye amaqhekeza ayo yi-needle coke esekelwe kumalahle. I-Coke.
