Ubukhulu be-Graphite Silicon Carbide Crucibles ku-Metal Melting Applications

Emkhakheni wokusebenza kwensimbi nokukhiqiza, ukukhethwa kwezinto ezibonakalayo kudlala indima ebalulekile ekunqumeni ukusebenza kahle, ikhwalithi, kanye nokusebenza kahle kwezindleko zenqubo yokuncibilika. Phakathi kwezinto ezihlukahlukene ezitholakalayo,graphite silicon carbide (SiC) crucibleszigqame ngezakhiwo zazo ezingavamile, okuzenza zibe yinketho ekhethwayo yezinhlelo zokusebenza zokuncibilikisa insimbi ezisezingeni eliphezulu. Lesi sihloko sicubungula izinzuzo eziyingqayizivele ze-graphite SiC crucibles uma kuqhathaniswa nezinye izinto ezifana ne-graphite ehlanzekile, i-alumina, nezinsimbi zensimbi, ezigqamisa ukusetshenziswa kwazo ezimbonini ezahlukene.

Ukuzinza Okumangalisayo Kokushisa kanye Nokumelana Nokushisa

I-graphite SiC crucibles ibonisa ukuzinza okushisayo okungenakuqhathaniswa kanye nokumelana nezinga lokushisa eliphezulu, ekwazi ukumelana nezindawo ezishisa njengo-1600°C kuya ku-1650°C. Lokhu kubekezelela ukushisa okuphawulekayo akuvumeli nje kuphela ukuncibilika kwezinsimbi ezincibilika kakhulu njengethusi, igolide, isiliva, nensimbi kodwa futhi kuqinisekisa ubuqotho be-crucible nokuphila isikhathi eside ngaphansi kwezimo ezishisayo ezishisayo. Ngokuphambene, izinto ezifana ne-graphite emsulwa ne-alumina zinikeza ukumelana nokushisa okuphansi, zikhawulela ukufaneleka kwazo kwezinye izinhlelo zokusebenza ezisezingeni eliphezulu.

I-Chemical Corrosion Resistance

I-inertness yamakhemikhali ye-graphite SiC crucibles kungenye inzuzo ephawulekayo, ehlinzeka ngokuqina ngokumelene nokuhlasela okulimazayo kwamakhemikhali ahlukahlukene ahilelekile ezinqubweni zokuncibilika kwensimbi. Lesi sici siqinisekisa ukuthi i-crucible ayingcolisi ukuncibilika, ukucatshangelwa okubalulekile kwezimboni lapho ukuhlanzeka kwensimbi kubaluleke kakhulu, njengokukhiqiza i-semiconductor kanye nokukhiqizwa kwamaphaneli elanga. Nakuba ama-graphite crucibles ahlanzekile nawo anokumelana okuhle namakhemikhali, angase angasebenzi kahle ezindaweni ezigqwalile uma kuqhathaniswa nezinsimbi ze-graphite SiC.

I-High Thermal Conductivity yokuncibilika Okuphumelelayo

I-thermal conductivity ephezulu ye-graphite SiC crucibles yenza kube lula ukusatshalaliswa kokushisa okusheshayo nokufana okufanayo, okubalulekile ekuncibilikeni kwensimbi okuphumelelayo nokungaguquguquki. Lesi sici sinciphisa kakhulu ukusetshenziswa kwamandla kanye nesikhathi sokuncibilika, sithuthukisa ukukhiqiza okuphelele kwenqubo yokuncibilika. I-graphite crucibles ehlanzekile yabelana ngalesi sici esizuzisayo, kodwa ama-graphite SiC crucibles ayihlanganisa nokuzinza okushisayo okuphakeme, enikeza inzuzo ehlukile ekusetshenzisweni okudingayo.

Izicelo Kuzo zonke Izimboni

Izakhiwo ezihlukile ze-graphite SiC crucibles zizenza zifanelekele uhla olubanzi lwezinhlelo zokusebenza ngaphandle kokuncibilika kwensimbi. Embonini ye-semiconductor, ukumelana kwazo emazingeni okushisa aphezulu kanye nokugqwala kwamakhemikhali kuzenza zilungele ukukhiqiza ama-silicon wafers nezinye izinto zokwakha ze-semiconductor. Umkhakha wamandla elanga nawo uzuza ekusetshenzisweni kwe-graphite SiC crucibles ekukhiqizeni i-silicon ephezulu yokuhlanzeka kwamapaneli elanga. Ngaphezu kwalokho, ukuqina nokusebenza kahle kwazo kuzenze zaba into ekhethwayo kumalabhorethri ocwaningo nasezinhlelweni ezikhethekile zokusebenza kwensimbi, lapho ukunemba nokwethembeka kubalulekile.

Isiphetho

I-graphite silicon carbide crucibles imelela inqubekelaphambili ebalulekile kubuchwepheshe be-crucible, enikeza ukusebenza okuphakeme kumazinga okushisa aphezulu, ukuhlanzeka okuphezulu, kanye nezinqubo zokuncibilikisa insimbi ezisebenza kahle kakhulu. Ukuzinza kwazo okungenakuqhathaniswa kokushisa, ukumelana namakhemikhali, kanye nokuguquguquka kokushisa kuzenza zibe yisinqumo esikhethwayo sezinhlelo zokusebenza ezihlukahlukene zezimboni nokucwaninga, ukubeka izindinganiso ezintsha zekhwalithi nokusebenza kahle emsebenzini wensimbi. Njengoba izimboni ziqhubeka nokuvela, isidingo sezinto zokwakha ezingamelana nezimo ezimbi kakhulu kuyilapho iletha ukusebenza okukhethekile silokhu sikhula, sibeka izinsimbi ze-graphite SiC phambili kwezesayensi yokukhiqiza nempahla yesimanje.

Lokhu kuhlola izinzuzo nokusetshenziswa kwezinsimbi ze-graphite SiC kugcizelela ukubaluleka kwazo endaweni yanamuhla yezimboni, okuhlinzeka ngemininingwane ngendima yazo ekuthuthukisweni kobuchwepheshe bokukhiqiza nokuba negalelo ekuthuthukisweni kwekhwalithi ephezulu, imikhiqizo emisha.
