I-graphite crucible isoloko isetyenziselwa ukuveliswa kwesinyithi kunye nezixhobo ze-semiconductor. Ukuze wenze izinto zetsimbi kunye ne-semiconductor zifikelele ekuhlambulukeni okuthile kwaye zinciphise inani lokungcola, i-graphite powder enomxholo ophezulu wekhabhoni kunye nokungcola okuncinci kuyadingeka. Ngeli xesha, kuyimfuneko ukususa ukungcola kwi-graphite powder ngexesha lokucubungula. Abathengi abaninzi abayazi indlela yokujongana nokungcola kwigraphite powder. Namhlanje, iFuruite Graphite Editor iya kuthetha malunga neengcebiso zokususa ukungcola kwigraphite powder ngokweenkcukacha:
Xa sivelisa i-graphite powder, kufuneka silawule ngokungqongqo umxholo wokungcola ekukhethweni kwezinto eziluhlaza, ukhethe izinto eziphathekayo ezinomlotha ophantsi, kwaye uthintele ukwanda kokungcola kwinkqubo yokucubungula i-graphite powder. I-oxides yezinto ezininzi ezingcolileyo zihlala zichithwa kwaye zikhutshwe kwiqondo lokushisa eliphezulu, ngaloo ndlela ziqinisekisa ukucoceka kwe-graphite powder eveliswayo.
Xa uvelisa iimveliso zegraphical jikelele, iqondo lobushushu elingundoqo le-furnace lifikelela malunga ne-2300 ℃ kwaye umxholo wokungcola okushiyekileyo umalunga ne-0.1% -0.3%. Ukuba iqondo lobushushu eliphambili lesithando somlilo liphakanyiselwe kwi-2500-3000℃, umxholo wobumdaka obushiyekileyo uya kuncitshiswa kakhulu. Xa uvelisa iimveliso ze-graphite powder, i-petroleum coke enomxholo ophantsi wothuthu idla ngokusetyenziswa njengezinto ezixhathisayo kunye ne-insulation material.
Nokuba iqondo lobushushu legraphitization linyuswe nje ukuya kuma-2800℃, okunye ukungcola kusenzima ukukususa. Ezinye iinkampani zisebenzisa iindlela ezinje ngokucutha undoqo wesithando somlilo kunye nokwandisa ukuxinana kwangoku ukukhupha umgubo wegraphite, okunciphisa ukukhutshwa kwesithando somgubo wegraphite kunye nokwandisa ukusetyenziswa kwamandla. Ke ngoko, xa iqondo lobushushu legrafu yesithando somlilo lifikelela kwi-1800 ℃, irhasi esulungekileyo, efana neklorini, ifreon kunye nezinye iikloridi kunye neefluorides, iye yaziswa, kwaye iyaqhubeka idityaniswa iiyure ezininzi emva kokusilela kombane. Oku kukuthintela ukungcola okwenziwa ngumphunga ukuba kungasasazeki kwiziko kwelinye icala, kunye nokukhupha igesi eseleyo ehlambulukileyo kwi-pores ye-graphite powder ngokuzisa i-nitrogen.
