I-Silicon Carbide ifumaneka ngeendlela ezimbini, i-reaction bonded kunye ne-sintered. Ngolwazi oluthe vetshe ngezi nkqubo zimbini nceda usithumelele i-imeyile apha[i-imeyile ekhuselweyo]
Zombini izixhobo zi-ultra-hard kwaye zine-conductivity ephezulu ye-thermal. Oku kukhokelele ekubeni i-silicon carbide isetyenziswe ekuthwaleni nasekufakweni kwesitywina esijikelezayo apho ukonyuka kokuqina kunye nokuhanjiswa kuphucula ukutywinwa kunye nokusebenza.
I-Reaction bonded silicon carbide (RBSC) ineempawu ezilungileyo kumaqondo obushushu aphezulu kwaye ingasetyenziswa kwizicelo ezichasayo.
Izinto zeSilicon carbide zibonisa ukhukuliseko olulungileyo kunye nokuxhathisa kwe-abrasive, ezi zakhiwo zinokusetyenziswa kwiintlobo ezahlukeneyo zezicelo ezifana nemibhobho yokutshiza, imibhobho yokudubula kunye namalungu e-cyclone.
IiNzuzo eziPhambili kunye neePropati zeSilicon Carbide Ceramics:
l Ukuhanjiswa kwe-thermal ephezulu
l I-coefficient yokwandisa i-thermal ephantsi
l Ukuxhathisa ukothuka kwe-thermal
l Ubunzima obugqithisileyo
l Semiconductor
l Isalathiso serefractive esikhulu kunedayimani
Ngolwazi oluthe kratya malunga neSilicon Carbide Ceramics nceda usithumelele i-imeyile[i-imeyile ekhuselweyo]
Imveliso yeSilicon Carbide
I-Silicon Carbide ivela kwi-powder okanye ingqolowa, eveliswa kwi-carbon yokunciphisa i-silica. Iveliswa njengomgubo ocolekileyo okanye ubunzima obukhulu obudityanisiweyo, obuthi ke bucunyuzwe. Ukucoca (ukususa i-silica) ihlanjwe nge-hydrofluoric acid.
Kukho iindlela ezintathu eziphambili zokwenza imveliso yorhwebo. Indlela yokuqala kukuxuba i-silicon carbide powder kunye nenye into efana neglasi okanye isinyithi, oku kunyangwa ukuvumela isigaba sesibini ukuba sibophe.
Enye indlela kukuxuba umgubo kunye nekhabhoni okanye i-silicon powder yesinyithi, ethi emva koko i-reaction ihlanganiswe.
Ekugqibeleni i-silicon carbide powder inokuxinwa kwaye ifakwe kwi-boron carbide okanye enye i-sintering aid ukwenza iiseramics ezinzima kakhulu. Kufuneka kuqatshelwe ukuba indlela nganye ifanelekile kwizicelo ezahlukeneyo.
