Amathiphu okukhipha ukungcola ku-graphite powder

I-graphite crucible ivame ukusetshenziswa ekukhiqizeni izinto zensimbi ne-semiconductor. Ukuze wenze izinto zensimbi neze-semiconductor zifinyelele ekuhlanzekeni okuthile futhi zinciphise inani lokungcola, i-graphite powder enokuqukethwe okuphezulu kwekhabhoni kanye nokungcola okuphansi kuyadingeka. Ngalesi sikhathi, kuyadingeka ukususa ukungcola kusuka ku-graphite powder ngesikhathi sokucubungula. Amakhasimende amaningi awazi ukuthi angabhekana kanjani nokungcola kwe-graphite powder. Namuhla, i-Furuite Graphite Editor izokhuluma ngamathiphu okususa ukungcola ku-graphite powder ngokuningiliziwe:

Lapho sikhiqiza i-graphite powder, kufanele silawule ngokuqinile okuqukethwe kokungcola kusukela ekukhethweni kwezinto zokusetshenziswa, khetha izinto ezingavuthiwe ezinomlotha ophansi, futhi uvimbele ukwanda kokungcola ohlelweni lokucubungula i-graphite powder. Ama-oxide ezakhi eziningi ezingcolile ahlala ebola futhi ahwamukile ekushiseni okuphezulu, ngaleyo ndlela aqinisekise ukuhlanzeka kwe-graphite powder ekhiqizwayo.

Lapho kukhiqizwa imikhiqizo ejwayelekile ye-graphitized, izinga lokushisa eliphakathi kwesithando somlilo lifinyelela cishe ku-2300 ℃ futhi okuqukethwe okusele kokungcola cishe ku-0.1% -0.3%. Uma izinga lokushisa lengqikithi yesithando somlilo likhushulelwa ku-2500-3000℃, okuqukethwe kokungcola okuyinsalela kuzoncipha kakhulu. Lapho kukhiqizwa imikhiqizo ye-graphite powder, i-petroleum coke enokuqukethwe komlotha ophansi ngokuvamile isetshenziswa njengezinto zokumelana nezinto zokufakelwa.

Ngisho noma izinga lokushisa le-graphitization limane lenyuke laya ku-2800 ℃, okunye ukungcola kusenzima ukukususa. Ezinye izinkampani zisebenzisa izindlela ezinjengokuncipha komgogodla wesithando somlilo nokwandisa ukuminyana kwamanje ukuze kukhishwe i-graphite powder, okunciphisa ukukhishwa kwesithando somlilo we-graphite futhi kwandise ukusetshenziswa kwamandla. Ngakho-ke, lapho izinga lokushisa lesithando somlilo se-graphite lifinyelela ku-1800 ℃, kwethulwa igesi ehlanzekile, njenge-chlorine, i-freon namanye ama-chloride nama-fluoride, futhi iyaqhubeka nokungezwa amahora ambalwa ngemva kokuphelelwa amandla. Lokhu kwenzelwa ukuvimbela ukungcola okuhwamukile ukuthi kungasakazeki esithandweni kolunye uhlangothi, nokukhipha igesi esele ehlanziwe ezimbotsheni ze-graphite powder ngokwethula initrogen ethile.
