Ikhabhoni edityaniswe nesilicon carbide crucible, isetyenziswa ngokubanzi kwiilebhu zobushushu obuphezulu. Ezi crucibles zibonelela ngeenzuzo ezahlukeneyo njengamandla aphezulu kunye nokuchasana ne-deformation kunye nokuphuka kumaqondo aphezulu. Nangona kunjalo, kubalulekile ukuqaphela ukuba nabo banezinye iingxaki ezifuna ukuqwalaselwa.
Enye yezinto ezingalunganga eziphambili kwi-silicon carbide crucibles bubuthathaka babo. Ezi crucibles zithande ukuphuka xa ziphantsi kokutshatyalaliswa komatshini ngexesha lokusetyenziswa. Xa yonakele, inokubangela ukuba imifuniselo ingaphumeleli okanye idibanise ukuchaneka kwedatha yovavanyo. Obu buthathaka kufuneka buthathelwe ingqalelo kwaye kuthathwe amanyathelo okhuseleko afanelekileyo ngexesha lokuphatha kunye nokusetyenziswa.
Enye into engalunganga ye-silicon carbide crucibles kukuba iyakwazi ukusabela kwi-oxidation kumaqondo aphezulu. Xa ibonakaliswe kumaqondo okushisa aphezulu, i-oxide layer inokwakheka phezu kwe-crucible, enokuphazamisa iziphumo zovavanyo. Kubalulekile ukukhusela le oxidation ngokuthatha amanyathelo okukhusela, njengokugubungela umphezulu we-crucible kunye nomgangatho okhuselayo.
Ukongeza, i-silicon carbide crucibles ixhomekeke kwimida ethile ngenxa yezinto ezifana nenkqubo yokuvelisa kunye neendleko. Le mida inokukhawulela ubungakanani, imilo, kunye nomthamo we-crucible. Ke ngoko, abaphandi kunye nabavelisi kufuneka bathathele ingqalelo le mida xa bekhetha ama-crucibles kwiimfuno zabo ezithile.
Ukujongana neentsilelo ze-silicon carbide crucibles, kukho izisombululo ezininzi ezikhoyo. Okokuqala, ukwenzela ukuba kuphuculwe ubomi benkonzo ye-crucible, iindlela zingasetyenziselwa ukuqinisa ukuxhaswa kwodonga lwangaphakathi ukuze zenze kube nzima ukunxiba kunye nokuqina. Oku kunceda ukuthintela ukuqhekeka kunye nokwandisa ubomi be-crucible.
Okwesibini, ukwenzela ukuthintela i-oxidation, umaleko okhuselayo ungasetyenziswa kumphezulu we-crucible. Olu luhlu luvimbela i-crucible ekuphenduleni nge-oksijini kumaqondo aphezulu, ngaloo ndlela ikhusela ukubunjwa kwe-oxide layer.
Okokugqibela, ukoyisa imida ye-silicon carbide crucibles, uyilo lunokuphuculwa kunye neenkqubo zokuvelisa eziphucukileyo zamkelwe. Ngokwenza njalo, iimilo ezinkulu, ezinzulu, kunye nezintsonkothileyo zinokudalwa, zivumela ukusetyenziswa kwezi crucibles kuluhlu olubanzi lokuseta uvavanyo. Ukongeza, ezinye izinto ezinje nge-ceramics zobushushu obuphezulu zinokuqwalaselwa endaweni ye-silicon carbide crucibles.
Ukuqukumbela, ii-silicon carbide crucibles zinezinto ezingalunganga, kodwa ukusetyenziswa kwazo kwilabhoratri kuseluncedo kakhulu. Ukusebenza ngokubanzi kunye nokuguquguquka kwe-silicon carbide crucibles kunokuphuculwa ngokuthatha amanyathelo afanelekileyo kunye nokulungiswa kokujongana no-brittleness yabo, ukuchaphazeleka kwi-oxidation, kunye nemida. Abaphandi kunye nabavelisi kufuneka baqwalasele le miba ngononophelo xa bekhetha iicrucibles zovavanyo lobushushu obuphezulu.
