Lisebelisoa tse tala tse sebelisoang tlhahiso ea toner hangata li kenyelletsa flake graphite, petroleum coke le enke ea majoe a microcrystalline. Ho hloeka ha graphite ho phahame, boleng ba tšebeliso bo phahame. Mekhoa ea ho hloekisa graphite e ka aroloa ka mekhoa ea 'mele le mekhoa ea lik'hemik'hale. Mekhoa ea tlhoekiso ea 'mele e kenyelletsa ho phaphamala le tlhoekiso ea mocheso o phahameng,' me mekhoa ea tlhoekiso ea lik'hemik'hale e kenyelletsa mokhoa oa acid-base, mokhoa oa hydrofluoric acid le mokhoa oa ho halika chloride. Har'a bona, mokhoa o phahameng oa ho hloekisa mocheso o ka sebelisa sebaka se phahameng sa ho qhibiliha (3773K) le ntlha e belang ea graphite ho finyella 4N5 le bohloeki bo phahameng, bo kenyelletsang ho tsoa mouoane le ho tsoa ha litšila tse nang le ntlha e tlaase e belang, e le ho finyella sepheo sa tlhoekiso [6]. Theknoloji e ka sehloohong ea toner e phahameng ea bohloeki ke ho tlosoa ha litšila.
