Ruushku waa soo dejinta saafiga ah ee electrodes graphite.Mugga sannadlaha ah ee soo dejinta ee graphite electrodes waa qiyaastii 40,000 tan, taas oo in ka badan kala badh kheyraadka ay ka yimaadaan Shiinaha, inta soo hartayna waxay ka yimaadaan India, France iyo Spain.Laakiin isla mar ahaantaana, Ruushku sidoo kale wuxuu leeyahay ku dhawaad ​​20,000 oo tan oo elektrodes graphite ah oo loo dhoofiyo sannad kasta, gaar ahaan Maraykanka, Midowga Yurub, Belarus, Kazakhstan iyo dalal kale.Maadaama inta badan foornooyinka korontada ku shaqeeya ee wadamada kor ku xusan ay ka sarreeyaan 150 tan, electrodes-ka graphite ee uu dhoofiyo Ruushka ayaa sidoo kale ah inta badan koronto-xawaad ​​aad u sarreeya.

Tilmaamaha budada graphite: korantada xooggan iyo kuleylka kuleylka, nadiifin sare iyo qaab dhismeedka crystalline sare, xasilloonida xooggan (molecules kaarboonka ayaa weli ah mid aan isbeddelin heerkulka sare), iyo saliidda sare.
Kaarboon Yunai wuxuu leeyahay waayo-aragnimo sanado badan ah soo saarista agab garaafeed, taasoo horseed u ah farsamaynta tignoolajiyada oo uu ka sareeyo waxqabadka qiimaha.Aqoon-is-weydaarsiga wax-soo-saarka budada graphite ee madax-bannaan wuxuu ku siin karaa budada garaafka tayada sare leh (nadiifinta sare, budada garaafka caadiga ah iyo ultra-fine) oo leh granularity kala duwan sida waafaqsan shuruudaha macaamiisha, iyo tusmooyinka jirka iyo kiimikaad ee alaabadu waxay ka sarreeyaan heerka celceliska warshadaha.
