Ukusebenza okugqwesileyo kwe-silicon carbide crystal boat kwindawo yobushushu obuphezulu

Isikhephe se-silicon carbide crystal sisixhobo esineempawu ezibalaseleyo, ezibonisa ubushushu obungaqhelekanga kunye nokumelana nokugqwala kwiindawo eziphakamileyo zobushushu. Yikhompawundi eyenziwe ngezinto zekhabhoni kunye ne-silicon ezinobunzima obuphezulu, indawo ephezulu yokunyibilika kunye ne-thermal conductivity egqwesileyo. Oku kwenza iinqanawa ze-silicon carbide crystal zilungele usetyenziso olwahlukeneyo lobushushu obuphezulu, obunje nge-aerospace, amandla enyukliya, iikhemikhali, njl.

Okokuqala, i-silicon carbide crystal boat inokumelana nobushushu obugqwesileyo kwiindawo eziphakamileyo zobushushu. Ngenxa yesakhiwo sayo esikhethekileyo se-crystal, i-silicon carbide crystal boat iyakwazi ukugcina iimpawu zayo zomzimba kunye neekhemikhali phantsi kweemeko ezinzulu zokushisa. Iyakwazi ukumelana namaqondo okushisa ukuya kwi-1500 degrees Celsius ngaphandle kokuguqulwa okanye ukuphuka, okwenza ukuba isetyenziswe ngokubanzi kwiqondo lokushisa eliphezulu lokunyibilika, ukusabela kobushushu obuphezulu kunye nezinye iinkqubo.

Okwesibini, isikhephe se-silicon carbide crystal sinokumelana nokugqwesa okugqwesileyo kwindawo yobushushu obuphezulu. Kwezinye iimeko zeekhemikhali ezigqithisileyo, ezininzi zetsimbi kunye nezinye izinto ziya kuchaphazeleka ngokubola, kodwa i-silicon carbide crystal boat inokugcina uzinzo. Ayingcoliswanga yi-asidi, i-alkali kunye nezinye izinto ezinobungozi, ezenza ukuba zisetyenziswe ngokubanzi kwiikhemikhali, ze-elektroniki kunye namanye amashishini.

Ukongeza, i-thermal conductivity ye-silicon carbide crystal boat ikwayenye yeenzuzo zayo. Ngenxa yesakhiwo sayo esiyingqayizivele se-crystal, i-silicon carbide crystal boat ine-conductivity ephezulu ye-thermal kwaye iyakwazi ukuqhuba ubushushu ngokukhawuleza kwaye igcine ukusabalalisa ukushisa okufanayo. Oku kuyenza isetyenziswe ngokubanzi kunyango lobushushu, ukwenziwa kwe-semiconductor kunye neminye imimandla.

Ngamafutshane, isikhephe se-silicon carbide crystal esinokumelana nobushushu obugqwesileyo, ukumelana nokugqwala kunye nokuhanjiswa kwe-thermal, ibe yeyona nto ifanelekileyo kwindawo yobushushu obuphezulu. Inoluhlu olubanzi lwezicelo, inokuhlangabezana neemfuno zeenkqubo ezahlukeneyo zobushushu obuphezulu, kwaye inamandla amakhulu ekuphuhlisweni kwexesha elizayo.
