Embonini yesimanje yokushisa okuphezulu,i-silicon carbide graphite crucibleisibe yinto ebalulekile ngenxa yezakhiwo zayo ezinhle kakhulu zokushisa, ukumelana namakhemikhali namandla aphezulu, futhi isetshenziswa kabanzi ekuncibilikiseni insimbi, ukukhiqiza ingilazi, ucwaningo lwaselabhorethri neminye imikhakha. Lesi sihloko sizocubungula izici eziyingqayizivele, ububanzi bohlelo lokusebenza kanye namathemba entuthuko yesikhathi esizayo ye-silicon carbide graphite crucibles.

Izici ze-silicon carbide graphite crucible
Inhlanganisela ye-silicon carbide (SiC) ne-graphite inikeza i-crucible izici ezinhle kakhulu zazo zombili izinto. Le nhlanganisela inikeza i-silicon carbide graphite crucibles izinzuzo ezibalulekile ezilandelayo:

Ukumelana nokushisa okuphezulu okuhle kakhulu: I-silicon carbide graphite crucible ingasebenza ngokuzinzile emazingeni okushisa angaphezu kuka-1600 ° C ngaphandle kokuncibilika noma ukuguqulwa.
Ukusebenza kahle kwe-thermal: I-thermal conductivity iphakeme kakhulu kunezinto ze-ceramic zendabuko, iqinisekisa ukusatshalaliswa kokushisa okufanayo ku-crucible kanye nokwenza ngcono ukusebenza kahle kokushisa.
Ukumelana nokugqwala kwamakhemikhali okuqinile: Ingakwazi ukumelana ngokuphumelelayo nokugqwala kwama-reagents amakhemikhali ahlukahlukene futhi yandise impilo yayo yesevisi.
Amandla emishini amahle kakhulu: Ukuhlanganisa ubulukhuni be-silicon carbide namandla e-graphite, ingagcina izakhiwo ezinhle zemishini ngisho nasezindaweni zokushisa okuphezulu.
Ukumelana nokushaqeka okuhle kakhulu kokushisa: Abajwayele ukuqhekeka ngesikhathi sezinqubo zokushisisa ngokushesha noma zokupholisa, okubenza balungele ukufudumeza okusheshayo noma izinqubo zokupholisa.
Izindawo zokufaka izicelo
I-silicon carbide graphite crucibles ihamba phambili ezinhlelweni eziningi zokushisa okuphezulu, okuhlanganisa:

Ukuncibilikiswa kwensimbi: Ngenxa yokuguquguquka kwayo okuhle kakhulu kokushisa nokumelana nokugqwala, isetshenziswa kakhulu ezinqubweni zokuncibilikisa nokucwengisiswa kwe-aluminium, ithusi, igolide nezinye izinsimbi.
Ukukhiqiza ingilazi: Nikeza ngendawo enezinga lokushisa eliphezulu ezinzile phakathi nenqubo yokuncibilika kwengilazi ukuze kuqinisekiswe ukufana kokuncibilika nokwakheka kwengilazi.
Ucwaningo lwaselabhorethri: Iziqukathi eziyisampula ezivame ukusetshenziswa ocwaningweni lwesayensi yezinto kanye nokuhlolwa kwezinga lokushisa eliphezulu ukuze kuhlinzekwe ngokulawula izinga lokushisa okunembayo.
Imboni yamakhemikhali: isetshenziswa emikhunjini ephendula izinga lokushisa eliphezulu nemikhumbi yokuphatha amakhemikhali abolayo nama-reactants asezingeni eliphezulu.
Amathemba entuthuko yesikhathi esizayo
Ngokuthuthuka okuqhubekayo kobuchwepheshe kanye nesidingo esikhulayo ezimbonini ezisezingeni eliphezulu, izinsimbi ze-silicon carbide graphite crucibles zinamathemba abanzi okusebenza. Ucwaningo nokuthuthukiswa kwesikhathi esizayo kuzogxila kulezi zici ezilandelayo:

Ukuthuthukiswa Kwezinto Ezibalulekile: Ucwaningo lwe-Nanotechnology nezinto eziyinhlanganisela luqhubekisela phambili ukuthuthukisa ukusebenza okushisayo kwe-crucible namandla emishini.
Ukulawulwa kwezindleko: Thuthukisa inqubo yokukhiqiza, unciphise izindleko zokukhiqiza, wenze izinsimbi ze-silicon carbide graphite zingabizi kakhulu, futhi wandise ububanzi bokusebenza kwazo.
Ukuthuthukiswa kwemvelo: Ukuthuthukisa izinto ezingasetshenziswa kabusha ezihambisana nemvelo ukuze kuncishiswe umthelela emvelweni futhi kukhuthaze ukuthuthukiswa kobuchwepheshe bezinga lokushisa eliphezulu eliluhlaza.
Ekuphetheni
Njengento esebenza kahle kakhulu, i-silicon carbide graphite crucible idlala indima ebalulekile embonini yesimanje yokushisa okuphezulu nokumelana kwayo okuvelele kokushisa okuphezulu, ukuqhutshwa kwe-thermal, ukumelana nokugqwala nezinye izici. Ngokuthuthuka okuqhubekayo kobuchwepheshe kanye nokwandiswa kwezinkambu zokufaka izicelo, i-silicon carbide graphite crucibles izodlala indima ebaluleke kakhulu kubuchwepheshe bezinga lokushisa eliphezulu lesikhathi esizayo futhi ikhuthaze ukukhiqizwa okusebenza kahle nokunobungani kwemvelo ezimbonini ezihlukahlukene.

Ngokuqonda okujulile kanye nokusetshenziswa kwe-silicon carbide graphite crucibles, impumelelo enkulu ingafinyelelwa ekucubunguleni izinga lokushisa eliphezulu, ukushayela inqubekelaphambili yezobuchwepheshe kanye nokuthuthukiswa kwezimboni.
