I-silicon ye-carbide cruciblesziyaziwa ngokusebenza kwazo okuphezulu kobushushu obuphezulu kwaye ziyakwazi ukumelana namaqondo obushushu aphezulu kakhulu okusebenza. Ngokuqhelekileyo, iicrucibles ze-silicon carbide ezikumgangatho ophezulu zinokusebenza ngokukhuselekileyo kwaye ngokuzinzileyo kuluhlu lobushushu lwe-1600 ° C ukuya kwi-2200 ° C (2912 ° F ukuya kwi-3992 ° F), kwaye ezinye iicrucibles eziyilwe ngokukodwa kwaye ziphathwe ziyakwazi ukumelana namaqondo okushisa ukuya kuma-2700 °. C (4952°F).
Kwizicelo ezisebenzayo kwiimvavanyo zobushushu obuphezulu okanye iinkqubo zokuvelisa ezifana nokunyibilika kwesinyithi kunye ne-ceramic sintering, iqondo lokushisa elithile elisebenzayo le-silicon carbide crucible kufuneka limiselwe ngokusekelwe kwiimfuno zenkqubo ethile, iimeko ze-atmospheric kunye neempawu zekhemikhali zezinto eziphathekayo. Ukongezelela, iinkqubo ezifanelekileyo zokusebenza kufuneka zilandelwe ukukhusela i-crucible ekuqhekekeni okanye yonakaliswe ngenxa yokutshintsha ngokukhawuleza kwiqondo lokushisa.
Nangona i-silicon carbide crucibles inokumelana nokushisa okuphezulu, kubalulekile ukuphepha ukugqithisa ubushushu bokusebenza okuphezulu ukukhusela umonakalo kwizinto eziphathekayo okanye ukubonakala kokungcola. Iinkqubo zokupholisa ezifanelekileyo kufuneka zilandelwe emva kokusetyenziswa ukuthintela ukuqhekeka xa kubekwe kwiindawo ezibandayo, kwaye kufuneka kuthathwe unonophelo ukuze kugwenywe impembelelo yomzimba egqithisileyo ngexesha lokusetyenziswa ukukhusela umonakalo.
