Usha garaafiga ee alaabada aan biraha ahayn, sida habka jarista kaarboonka ee goynta qafiska ee loo baahan yahay marka la isticmaalayo jarista alxanka kahor, waxay ka samaysan tahay kaarboon, garaafit iyo dhejis ku habboon, iyada oo loo marayo sameynta xoqidda, ka dib 2200℃Wareegga dubista ka dib marka la dahaadho lakab naxaas ah oo la sameeyay, iska caabin heerkul sare leh, koronto-qaadis wanaagsan, aan si fudud loo jabin karin, oo ku habboon in birta loo jaro qaabka loo baahan yahay.
Ulaha garaafiga waxaa badanaa loo isticmaalaa jirka kuleylinta ee foornada faakuumka heerkulka sare leh, heerkulka ugu badan ee isticmaalka wuxuu gaari karaa 3000°C, way fududahay in oksaydh lagu sameeyo heerkul sare, marka lagu daro faakiyuumka, waxaa loo isticmaali karaa oo keliya jawi dhexdhexaad ah ama jawiga oo yareynaya. Isku-darka ballaarinta kulaylka waa yar yahay, isku-darka kulaylka waa weyn yahay, isku-darka iska caabinta waa (8~13)× 10-6Ω ·m, habka wax-qabadku wuu ka fiican yahay SiC, usha MoSi2, iska caabbinta heerkulka sare, qabow aad u daran iyo iska caabbinta kulaylka daran, qiimuhu waa ka jaban yahay.
Dhalaalidda dahabka Platinum iyo dahaarka. Astaamaha Graphite: iska caabin oksaydh oo xooggan, iska caabin hoose, heerkulka isticmaalka ilaa 1800 darajo Celsius iyo iska caabin daxalka.
Usha Graphite-ka ee sahay usha garaafitka, usha garaafitka ee dhulka lagu riixay, usha garaafitka ee isostatic-ka ah ee la riixay, shaabadda hiphite/carbon-graphite/kaarboon-graphite ee la qaadi karo/garaafitka EDM.
