Ukusebenza okuhle kakhulu kwesikebhe se-silicon carbide crystal endaweni yokushisa ephezulu

Isikebhe se-silicon carbide crystaliyinto enezinto ezinhle kakhulu, ekhombisa ukushisa okungajwayelekile nokumelana nokugqwala ezindaweni zokushisa okuphezulu. Kuyinhlanganisela eyakhiwe ngezinto ze-carbon ne-silicon ezinokuqina okuphezulu, indawo ephezulu yokuncibilika kanye ne-thermal conductivity enhle kakhulu. Lokhu kwenza izikebhe ze-silicon carbide crystal zilungele ukusetshenziswa okuhlukahlukene kokushisa okuphezulu, njenge-aerospace, amandla enuzi, amakhemikhali, njll.

Okokuqala, iisikebhe se-silicon carbide crystalinokumelana nokushisa okuhle kakhulu ezindaweni ezishisayo. Ngenxa yesakhiwo sayo esikhethekile se-crystal, i-isikebhe se-silicon carbide crystaliyakwazi ukugcina izakhiwo zayo ezingokomzimba namakhemikhali ngaphansi kwezimo zokushisa ezeqisayo. Ingakwazi ukumelana namazinga okushisa afinyelela ku-1500 degrees Celsius ngaphandle kokuguquka noma ukuphuka, okwenza isetshenziswe kabanzi ekuncibilikeni kwezinga lokushisa eliphezulu, ukusabela okuphezulu kwezinga lokushisa nezinye izinqubo.

Okwesibili, iisikebhe se-silicon carbide crystalinokumelana nokugqwala okuhle kakhulu endaweni yokushisa ephezulu. Kwezinye izindawo zamakhemikhali ezeqisayo, izinsimbi eziningi nezinye izinto zizothinteka ngokugqwala, kodwa isikebhe se-silicon carbide crystal singagcina ukuzinza kwaso. Ayidliwe yi-asidi, i-alkali nezinye izinto ezigqwalile, okuyenza isetshenziswe kabanzi ezimbonini zamakhemikhali, zikagesi nezinye.

Ngaphezu kwalokho, i-conductivity ezishisayoisikebhe se-silicon carbide crystalfuthi ingenye yezinzuzo zayo. Ngenxa yesakhiwo sayo esiyingqayizivele se-crystal, isikebhe se-silicon carbide crystal sine-conductivity ephezulu yokushisa futhi siyakwazi ukuqhuba ukushisa ngokushesha futhi sigcine ukusabalalisa ukushisa okufanayo. Lokhu kuyenza isetshenziswe kabanzi ekwelapheni ukushisa, ekukhiqizeni ama-semiconductor neminye imikhakha.

Kafushane,isikebhe se-silicon carbide crystalngokumelana kwayo nokushisa okuhle kakhulu, ukumelana nokugqwala kanye ne-thermal conductivity, ibe yinto efanelekile endaweni yokushisa ephezulu. Inezinhlobonhlobo zezinhlelo zokusebenza, ingahlangabezana nezidingo zezinqubo ezihlukahlukene zokushisa okuphezulu, futhi inamandla amakhulu ekuthuthukisweni kwesikhathi esizayo.
