I-Graphite crucible idla ngokusetyenziswa ekuvelisweni kwezinto zesinyithi kunye neze-semiconductor. Ukuze izinto zesinyithi kunye neze-semiconductor zifikelele kubunyulu obuthile kwaye zinciphise ukungcola, kufuneka umgubo we-graphite onomxholo ophezulu wekhabhoni kunye nokungcola okuphantsi. Ngeli xesha, kuyimfuneko ukususa ukungcola kwi-graphite powder ngexesha lokucubungula. Abathengi abaninzi abazi ukuba bajongane njani nokungcola kwi-graphite powder. Namhlanje, uMhleli we-Furuite Graphite uza kuthetha ngeengcebiso zokususa ukungcola kwi-graphite powder ngokweenkcukacha:
Xa sivelisa umgubo wegrafiti, kufuneka silawule ngokungqongqo umxholo wokungcola ekukhetheni izinto ezikrwada, sikhethe izinto ezikrwada ezinomlotha omncinci, kwaye sithintele ukwanda kokungcola kwinkqubo yokucubungula umgubo wegrafiti. Ii-oxide zezinto ezininzi ezingcolileyo zihlala zibola kwaye ziphuma kubushushu obuphezulu, ngaloo ndlela siqinisekisa ubunyulu bomgubo wegrafiti ovelisiweyo.
Xa kuveliswa iimveliso ezijikelezileyo zegrafiti, ubushushu besiseko sefurnace bufikelela malunga ne-2300℃ kwaye umxholo wokungcola okuseleyo umalunga ne-0.1%-0.3%. Ukuba ubushushu besiseko sefurnace bunyuswa bufikelele kwi-2500-3000℃, umxholo wokungcola okuseleyo uya kuncipha kakhulu. Xa kuveliswa iimveliso zomgubo wegrafiti, i-petroleum coke enomxholo ophantsi womlotha idla ngokusetyenziswa njengezinto zokuxhathisa kunye nezinto zokugquma.
Nokuba iqondo lobushushu be-graphitization linyuswe nje ukuya kwi-2800℃, ezinye izinto ezingcolileyo zisenzima ukuzisusa. Ezinye iinkampani zisebenzisa iindlela ezifana nokunciphisa isiseko sesithando somlilo kunye nokwandisa uxinano lwangoku ukuze kukhutshwe umgubo we-graphite, nto leyo enciphisa imveliso yesithando somlilo we-graphite powder kwaye yonyusa ukusetyenziswa kwamandla. Ke ngoko, xa ubushushu besithando somlilo we-graphite powder bufikelela kwi-1800℃, igesi ecociweyo, efana ne-chlorine, i-freon kunye nezinye ii-chloride kunye ne-fluoride, iyangeniswa, kwaye iyaqhubeka nokongeza iiyure ezininzi emva kokusilela kombane. Oku kwenzelwa ukuthintela ukungcola okuphekwe ngumphunga ukuba kungene kwisithando somlilo kwicala elichaseneyo, kunye nokukhupha igesi ecociweyo eseleyo kwimingxunya yomgubo we-graphite ngokungenisa i-nitrogen ethile.
