I-Silicon Carbide Crucible: Inketho Engcono Kakhulu Yokuncibilikisa Izinsimbi

Emkhakheni wokucubungula insimbi kanye ne-metallurgy,i-silicon carbide cruciblesavele njengamathuluzi abalulekile, atuswa ukusebenza kwawo okuhle kakhulu nokuqina. Ukwethulwa kwezinsimbi ze-silicon carbide crucible kuthuthukise kakhulu ukusebenza kahle kanye nekhwalithi yenqubo yokuncibilikisa insimbi. Lawa ma-crucibles adume ngezinto zawo ezibonakalayo eziyingqayizivele, ezizenza zikwazi ukumelana nezinga lokushisa eliphezulu futhi zimelane nokugqwala kwamakhemikhali, ziqinisekise ukusebenza okuzinzile ngisho nasezimweni ezimbi kakhulu.

I-silicon carbide crucibles ikhiqizwa ngezinto ezisezingeni eliphakeme ze-silicon carbide, ezaziwa ngobulukhuni bayo obukhethekile kanye ne-thermal conductivity. Lezi zakhiwo ziqinisekisa ukuthi i-crucible igcina ubuqotho bayo besakhiwo ngisho nangaphansi kwezimo zokushisa eziqinile zokuncibilika kwensimbi. Ngokungafani nezinsimbi ze-graphite crucibles, izinsimbi ze-silicon carbide ziqhayisa impilo ende yesevisi. Awohloki kalula lapho esetshenziswa futhi amelana nokusabela ngezinsimbi ezincibilikisiwe, okubalulekile ekugcineni ukuhlanzeka kwensimbi encibilikisiwe.

Esinye sezici ezivelele ze-silicon carbide crucibles ukumelana kwazo namazinga okushisa aphezulu. Bangakwazi ukubekezelela izimfuno ezinzima zezinqubo zokuncibilikisa insimbi, okuvame ukubandakanya amazinga okushisa afinyelela ezinkulungwaneni ezimbalwa zamadigri Celsius. Ukwengeza, lezi zinsimbi zibonisa ukumelana okuphawulekayo nokugqwala kwamakhemikhali, okuzivumela ukuthi zingathintwa izimo zamakhemikhali ezinonya ezivame ukuhlangana nazo ngesikhathi sokuncibilikiswa kwensimbi. Lokhu kumelana kuqinisekisa ukuthi ama-crucibles aqhubeka nokusebenza kahle kakhulu esikhathini eside.

Enye inzuzo ebalulekile ye-silicon carbide crucibles yi-coefficient yabo ephansi yokwanda okushisayo. Lesi sici sinciphisa ubungozi bokuqhekeka phakathi nemijikelezo yokushisisa nokupholisa okusheshayo, isenzakalo esivamile ezinqubweni zokuncibilikisa nokuphonsa. Amandla okumelana nalezi zingcindezi ezishisayo enza ama-silicon carbide crucibles afaneleke ikakhulukazi izinhlelo zokusebenza ezifunwayo ezifana nokusakazwa kwensimbi kanye nokukhiqizwa kwe-alloy. Kungakhathaliseki ukuthi kusendaweni yaselabhorethri ngezinjongo zocwaningo noma ekukhiqizweni kwezimboni ezinkulu, i-silicon carbide crucibles ihlangabezana ngokuqhubekayo nezidingo ezihlukahlukene zokusebenza kokucubungula insimbi.

Ukuguquguquka nokuthembeka kwe-silicon carbide crucibles kuholele ekwamukelweni kwazo okusabalele kuzo zonke izinhlelo zokusebenza ze-metallurgical. Ocwaningweni lwaselabhorethri, bahlinzeka ngokulawula okunembayo ezinqubweni zokuncibilika, okwenza ososayensi bakwazi ukwenza izivivinyo ngokunemba okuphezulu. Ezilungiselelweni zezimboni, ukuqina nokusebenza kwazo kunomthelela ekwandiseni ukusebenza kahle kokukhiqiza kanye nokunciphisa izindleko zokusebenza.

Ngokufigqiwe,i-silicon carbide crucibles kancane kancane ashintsha ama-crucibles endabuko, abe yinketho ekhethwayo embonini yesimanje yensimbi ngenxa yokusebenza kwayo okuhle kakhulu kanye namathemba okusebenza abanzi. Njengoba ubuchwepheshe buqhubeka nokuthuthuka, kulindeleke ukuthi izinsimbi ze-silicon carbide zizodlala indima ebaluleke nakakhulu esikhathini esizayo semboni yokucubungula insimbi. Ikhono labo lokubekezelela izimo ezimbi kakhulu, kuhambisana nokuphila isikhathi eside nokwethembeka, libabeka njengenketho engcono kakhulu yezinhlelo zokusebenza zokuncibilikisa insimbi.
