I-carbon bonded silicon carbide crucible, isetshenziswa kabanzi kuma-laboratories okushisa okuphezulu.Lawa ma-crucibles anikeza izinzuzo ezahlukahlukene njengamandla aphezulu kanye nokumelana nokuguqulwa nokuqhekeka emazingeni okushisa aphezulu.Nokho, kuyaphawuleka ukuthi nabo banezinkinga ezithile okufanele zicatshangelwe.
Enye yezinto ezimbi kakhulu ze-silicon carbide crucibles ubuthakathaka babo.Lawa ma-crucibles athambekele ekuqhekekeni lapho ehlaselwa ukushaqeka komshini ngesikhathi sokusetshenziswa.Uma zonakalisiwe, zingabangela ukuhlola ukuthi kuhluleke noma konakalise ukunemba kwedatha yokuhlola.Lokhu kuba sengozini kufanele kucatshangelwe futhi kuthathwe izinyathelo ezifanele ngesikhathi sokuphatha nokusebenzisa.
Okunye okungalungile kwe-silicon carbide crucibles ukuthi ijwayele ukusabela kwe-oxidation emazingeni okushisa aphezulu.Uma kuvezwa amazinga okushisa aphezulu, ungqimba lwe-oxide lungakheka endaweni ye-crucible, engaphazamisa imiphumela yokuhlola.Kubalulekile ukuvimbela lokhu ku-oxidation ngokuthatha izinyathelo zokuzivikela, njengokumboza indawo ye-crucible ngesendlalelo sokuzivikela.
Ngaphezu kwalokho, i-silicon carbide crucibles ingaphansi kwemikhawulo ethile ngenxa yezinto ezifana nenqubo yokukhiqiza kanye nezindleko.Le mikhawulo ingakhawulela usayizi, umumo, kanye nomthamo we-crucible.Ngakho-ke, abacwaningi nabakhiqizi badinga ukucabangela le mikhawulo lapho bekhetha ama-crucible ngezidingo zabo ezithile.
Ukubhekana nokushiyeka kwe-silicon carbide crucibles, izixazululo eziningana ziyatholakala.Okokuqala, ukuze kuthuthukiswe impilo yesevisi ye-crucible, izindlela zingasetshenziswa ukuqinisa ukusekelwa odongeni lwangaphakathi ukuze zenze kube nzima ukugqoka nokuqina.Lokhu kusiza ukuvimbela ukuphuka futhi kunwebe impilo ye-crucible.
Okwesibili, ukuze kuvinjelwe i-oxidation, ungqimba oluvikelayo lungasetshenziswa ebusweni be-crucible.Lesi sendlalelo sivimbela i-crucible ukuthi ingaphenduli nge-oxygen emazingeni okushisa aphezulu, ngaleyo ndlela ivimbele ukwakheka kongqimba lwe-oxide.
Okokugcina, ukuze unqobe imikhawulo ye-silicon carbide crucibles, umklamo ungathuthukiswa futhi wamukelwe izinqubo zokukhiqiza ezithuthuke kakhulu.Ngokwenza kanjalo, amajamo amakhulu, ajulile, futhi ayinkimbinkimbi kakhulu angadalwa, okuvumela ukusetshenziswa kwalezi ziphambano kuhlu olubanzi lokusetha kokuhlola.Ukwengeza, ezinye izinto ezinjengama-ceramics asezingeni eliphezulu zingase zicatshangelwe ukuthi zithathe indawo ye-silicon carbide crucibles.
Sengiphetha, izinsimbi ze-silicon carbide zinezinkinga ezithile, kodwa ukusetshenziswa kwazo elabhorethri kusazuzisa kakhulu.Ukusebenza sekukonke kanye nokuguquguquka kwe-silicon carbide crucibles kungathuthukiswa ngokuthatha izinyathelo ezifanele nokulungiswa ukuze kubhekwane nobulukhuni bazo, ukuba sengozini kwe-oxidation, kanye nemikhawulo.Abacwaningi nabakhiqizi kufanele bacabangele lezi zici ngokucophelela lapho bekhetha ama-crucibles okuhlola ezinga lokushisa eliphezulu.
