Kwicandelo lemizi-mveliso, iipayipi zizinto ezibalulekileyo zokuthutha izixhobo ezahlukeneyo, kwaye ukusebenza kwazo kuchaphazela ngokuthe ngqo ukusebenza kakuhle kwemveliso kunye nokhuseleko. Ngokuqhubeka kwesayensi yezinto,imibhobho ye-silicon carbideziye zavela kwaye zavela kancinci kancinci kumashishini amaninzi aneempawu ezininzi ezintle.
I-silicon carbide, ngokwendlela ekwakhiwe ngayo, yi-compound eyenziwe zizinto ezimbini: i-silicon (Si) kunye ne-carbon (C). Ngokwembono ye-microscopic, ii-athomu zayo ziqhagamshelwe ngokuqinileyo ngee-covalent bonds, zenza isakhiwo se-lattice esizinzileyo nesicwangcisiweyo. Esi sakhiwo sikhethekileyo sinika iipayipi ze-silicon carbide uluhlu lweempawu ezibalaseleyo.
Okokuqala, iipayipi ze-silicon carbide zinokumelana nokuguguleka okuhle kakhulu. Kwezinye iindawo ezifuna ukuthuthwa kwee-particles eziqinileyo, ezifana nokuthuthwa komgubo wamalahle ekuveliseni umbane oshushu kunye nokuthuthwa kodaka lwe-ore kwishishini lezemigodi, iipayipi eziqhelekileyo ziya kukhawuleza ziguge, zinciphe, kwaye zibhoboke phantsi kokuguguleka okuqhubekayo kwee-particles, nto leyo ebangela ukutshintshwa rhoqo kweepayipi, nto leyo enganyusi nje iindleko kodwa ikwachaphazela imveliso. Iipayipi ze-silicon carbide, ngenxa yeempawu zazo zobulukhuni obuphezulu, zinokumelana ngempumelelo nokuguguleka kwee-particles, zandise kakhulu ubomi benkonzo yeepayipi kwaye zinciphise ukugcinwa nokutshintshwa rhoqo.
Okwesibini, ukumelana nobushushu obuphezulu beepayipi ze-silicon carbide kuyamangalisa kakhulu. Kwiindawo ezinobushushu obuphezulu, amandla eepayipi zesinyithi eziqhelekileyo aya kuncipha kakhulu, kwaye neengxaki zinokuvela nokuba nokuguquguquka, ukuthamba, kunye nezinye iingxaki. Umzekelo, kumashishini anobushushu obuphezulu afana nokuvelisa isinyithi kunye neglasi, amaqondo obushushu anokufikelela kumakhulu okanye amawaka eedigri zeCelsius. Phantsi kweemeko ezinjalo zobushushu obuphezulu, iipayipi ze-silicon carbide zisenokugcina iipropati zomzimba nezekhemikhali ezizinzileyo, ziqinisekisa ukusebenza okuqhelekileyo kweepayipi kwaye zigcina imveliso iqhubeka.
Okokugqibela, iipayipi ze-silicon carbide nazo zinokumelana okuhle nokugqwala. Kwinkqubo yokuveliswa kweekhemikhali, kudla ngokubandakanya ukuthuthwa kwezinto ezahlukeneyo ezigqwala ezifana nee-asidi ezinamandla kunye nee-alkali. Iipayipi zemveli zidla ngokugqwala, okukhokelela ekuvuzeni okuphakathi, okungachithi nje kuphela izixhobo kodwa kunokubangela neengozi zokhuseleko. Iipayipi ze-silicon carbide, kunye nokuzinza kwazo kweekhemikhali, zinokumelana nokugqwala kweekhemikhali ezahlukeneyo, ziqinisekise ukhuseleko kunye nokuzinza kwemveliso.
Iipayipi ze-silicon carbide, ezineenzuzo ezininzi ezifana nokungagugi, ukumelana nobushushu obuphezulu, kunye nokungagqwali, ngokuthe ngcembe ziba yeyona nto ithandwayo kwicandelo leepayipi zoshishino, zibonelela ngeziqinisekiso eziqinileyo zemveliso esebenzayo nezinzileyo kumashishini amaninzi. Ngophuhliso oluqhubekayo lwetekhnoloji kunye nokuphuculwa ngakumbi kweendleko, sikholelwa ukuba iipayipi ze-silicon carbide ziya kuba noluhlu olubanzi lwezicelo kunye namathuba ophuhliso olubanzi kwixesha elizayo.
