Hoelectrode ea graphitebakeng sa ho etsa tšepe kapa peista ea anode bakeng sa aluminium le ho etsa magnesium (elektrode e qhibilihisang), e le ho etsa coke ea petroleum (coke) ho finyella litlhoko, coke e calcined.Mocheso oa calcination, petroleum coke volatiles li nkoa e le lintlha.

(1) Tlosa mongobo le lintho tse sa tsitsang linthong tse tala

Likahare tse sa tsitsang tsa thepa e tala li ka felisoa ka calcination, kahoo ho eketsa carbon content e tsitsitseng ea lihlahisoa tse tala.Metsi a lintho tse tala a felisitsoe ke calcination, e thusang ho silakanya, ho hlahloba le ho sila, ho ntlafatsa ts'ebetso ea adsorption ea lisebelisoa tse tala tsa carbon ho binder, le ho ntlafatsa boleng ba lihlahisoa.

(2) Ntlafatsa ho teteana le matla a mochini a lisebelisoa tse tala

Ka mor'a ho ba calcined, thepa ea carbon e fokotseha ka bongata, e eketseha ka sekhahla le matla ka lebaka la ho felisoa ha li-volatiles, 'me e fumana botsitso bo ntlafetseng ba mocheso, kahoo e fokotsa ho fokotseha ha bobeli ha lihlahisoa nakong ea calcination.

(3) Ntlafatsa conductivity ea lihlahisoa tse tala

Ka mor'a calcination, li-volatile li tlosoa, 'me sebopeho sa limolek'hule le sona se fetoha, ho fokotsa matla a motlakase le ho ntlafatsa motlakase oa thepa e tala.Ha re bua ka kakaretso, ha tekanyo ea calcination e phahame, ho molemo hore ho be le conductivity ea thepa ea calcined.

(4) Ntlafatsa khanyetso ea oxidation ea lisebelisoa tse tala

Ka mor'a calcination, ha mocheso oa carbon e tala o ntse o phahama, litšila tse kang hydrogen, oksijene le sebabole li tla ntšoa ka tatellano ka mokhoa oa pyrolysis le polymerization, 'me ts'ebetso ea lik'hemik'hale e tla fokotseha' me thepa ea 'mele le ea lik'hemik'hale e tla tsitsa, kahoo ho ntlafatsa oxidation. khanyetso ea lihlahisoa tse tala.

Calcined char e sebelisoa haholo-holo tlhahiso eaelectrode ea graphite, lihlahisoa tsa carbon paste, carborundum, indasteri ea phosphorus ea lijo, indasteri ea metallurgic le calcium carbide, eo har'a eona electrode ea graphite e sebelisoang ka ho fetisisa.'Me coke ntle le ho chesa ho ka sebelisoa ka ho toba bakeng sa khalsiamo carbide e le thepa e ka sehloohong, tlhahiso ea silicon carbide le boron carbide e le lisebelisoa tsa ho sila, empa hape le bakeng sa ts'ebetso ea ho lahla ka coke e teteaneng le likarolo tse ling.
