Umgubo wegrafiti luhlobo lomthombo wezimbiwaumguboenokwakheka okubalulekileyo. Icandelo layo eliphambili yikhabhoni elula, ethambileyo, engwevu emnyama kwaye inamafutha. Ubulukhuni bayo yi-1 ~ 2, kwaye iyanda iye kwi-3 ~ 5 xa kusanda umxholo wokungcola kwicala elithe nkqo, kwaye ubunzima bayo obuthile yi-1.9 ~ 2.3 Phantsi kwemeko yokwahlula umoya kunye neoksijini, indawo yayo yokunyibilika ingaphezulu kwe-3000℃, enye yezona zixhobo zezimbiwa ezimelana nobushushu.
Kwiqondo lobushushu begumbi, indlela yokuhlalutya ulwazi lweekhemikhali, ulwakhiwo kunye neempawu zazoumgubo wegrafayithiicwangcisiwe kwaye izinzile, kwaye ayinyibiliki emanzini, inyibilikiswe yi-asidi, inyibilikiswe yi-alkali kunye nesinyibilikisi sendalo. Umsebenzi wophando lwesayensi yezinto ezibonakalayo unentsebenzo ethile yokhuseleko lwenethiwekhi yokuqhuba edibeneyo enganyangekiyo kubushushu obuphezulu, enokusetyenziswa njengezinto eziphambili zoyilo olunganyangekiyo kumlilo, izixhobo ezisebenzayo eziqhubayo kunye nezixhobo zobugcisa zokuthambisa ezinganyangekiyo.
Kwiimeko zobushushu ezahlukeneyo eziphezulu, isabela kunye neoksijini ukuze iveliseikhabhonii-dioxide okanye i-carbon monoxide. Phakathi kwekhabhoni, yi-fluorine kuphela enokuthi iphendule ngqo kwi-elemental carbon. Xa ishushu, i-graphite powder ifakwa lula kwi-asidi. Kubushushu obuphezulu, i-graphite powder inokusabela kwiintsimbi ezininzi ukuze yenze ii-metal carbides, kwaye iintsimbi zinokunyibilikiswa kubushushu obuphezulu.
Umgubo wegrafiti yinto ebuthathaka kakhulu kwimpendulo yeekhemikhali, kwaye ukumelana kwayo kuya kutshintsha phantsi kweemeko ezahlukeneyo.Umgubo wegrafitisisixhobo esiqhubayo esingeyontsimbi esilungileyo kakhulu. Ukuba nje umgubo wegrafiti ugcinwe kwizinto zokukhusela, uya kutshajwa njengocingo oluncinci, kodwa ixabiso lokuxhathisa alilonani lichanekileyo. Ngenxa yokuba ubukhulu bomgubo wegrafiti bahlukile, ixabiso lokuxhathisa lomgubo wegrafiti liya kwahluka ngokwahluka kwezinto kunye nokusingqongileyo.
