Muva nje, izikebhe zekristalu ze-silicon carbide zidonsele ukunaka kwabezindaba bomhlaba wonke. Ziyisikebhe sekristalu esimangalisayo esenziwe ngobuchwepheshe be-silicon carbide. Asigcini nje ngokubukeka okumangalisayo, kodwa futhi sinamandla. Ngobuhle baso obuyingqayizivele kanye nokusebenza okuhle kakhulu ukuheha inani elikhulu labathengi. Igobolondo laso lenziwe ngezinto ze-silicon carbide, ukumelana nokushisa okuphezulu, ukumelana nokushisa okuphansi, ukumelana nomlilo, ukumelana nokugqwala, ukumelana nomswakama nokushisa, ukumelana nokugqwala kwamakhemikhali, ukumelana nomoya, ukumelana nokugqwala okuhle, impilo yesevisi ende. Ngaphezu kwalokho, isakhiwo saso sangaphakathi naso simangalisa kakhulu, ngokusebenza okuphezulu, singanikeza amandla amahle kakhulu okubamba, amandla aphezulu, ukuzinza okuphezulu kokushisa, ukumelana nokukhathala kwekhwalithi ephezulu, i-coefficient ephansi yokungqubuzana, kanye nezakhiwo ezinhle zokufaka ugesi.
Ngaphezu kwamandla ayo amakhulu, isikebhe sekristalu se-SIC naso siyasimeme. Izinto zaso zithathwe emandleni avuselelekayo, anganciphisa ngempumelelo ukungcola futhi asize ekuvikeleni imvelo. Ngaphezu kwalokho, inqubo yaso yokukhiqiza nayo inobungani kakhulu nemvelo, inganciphisa kakhulu ukusetshenziswa kwamandla, ithuthukise ukusebenza kahle kokukhiqiza, inciphise ukusetshenziswa kwamandla, ngaleyo ndlela yonge izindleko.
Njengokusungula okusha kwesayensi nobuchwepheshe, isikebhe sekristalu se-SIC sishintshe kakhulu ukuqonda kwabantu ngesikebhe sekristalu sendabuko. Asigcini nje ngokuba nokusebenza okuhle, kodwa futhi singavikela imvelo kangcono. Ukuvela kwaso kuzoletha ukusungula okusha kwesayensi nobuchwepheshe emphakathini wesintu.
Uma ubuchwepheshe besikhathi esizayo buzoshintsha impilo yabantu, khona-ke isikebhe sekristalu se-silicon carbide kungathiwa siyisibonelo sobuchwepheshe besikhathi esizayo.
Isikebhe sekristalu se-silicon carbide uhlobo olusha lwezinto ezihlanganisiwe, ezenziwa ngokuxuba nokushisa izinhlayiya ezincane ze-carbon fiber kanye ne-silicon powder. Izinto ezintsha zinezakhiwo ezifana nokumelana nokushisa, ukuguguleka, ukugqwala, ukukhukhuleka kanye nokushayisana, zingasebenza emazingeni okushisa aphezulu futhi zimelane nemisebe yesikhala enamandla, futhi zingasetshenziswa ezinhlotsheni ezifana nezindiza kanye nokuhlola isikhala, okusivumela ukuthi sihlole isikhala esijulile.
Isikebhe sekristalu se-silicon carbide singasetshenziswa hhayi kuphela ezindiza, kodwa nasemkhakheni wezokwelapha. Singasetshenziswa ukwenza amathuluzi ezokwelapha asezingeni eliphezulu, njengemishini yokujikeleza kwegazi yangaphandle komzimba kanye nezikena ze-ultrasound, kanye namarobhothi okuhlinzwa, okuyizibonelo zokusetshenziswa kobuchwepheshe besikebhe se-silicon carbide. Singasetshenziswa futhi ukwakha ama-nanorobots asebenza kahle kakhulu angalawula ama-molecule namaseli ngokunemba.
Isikebhe sekristalu se-silicon carbide ngokungangabazeki ubuchwepheshe obubalulekile obuzoshintsha ikusasa lesintu, futhi buzoletha amathuba angenamkhawulo okuthuthukiswa kobuchwepheshe babantu. Buphinde bunikeze ithuba lesintu lokudala ikusasa elijulile, okuvumela isintu ukuthi sihlole ubuchwepheshe obengeziwe futhi sifeze amaphupho esikhathi esizayo.
Isikebhe sekristalu se-silicon carbide siwuhlobo olusha lwesikebhe, siwukuhlanganiswa kwesayensi nobuchwepheshe kanye nobuciko. Ukubukeka kwesikebhe sekristalu se-silicon carbide kuyamangalisa kakhulu, kuyisitayela sokuklama sesimanje, sisebenzisa i-carbon fiber, i-silica nezinye izinto eziningi zobuchwepheshe.
Isici esiyinhloko sesikebhe sekristalu se-silicon carbide ukuma kwaso okuyingqayizivele kanye nomklamo waso. Ngokungafani nezikebhe zendabuko, sinomklamo ohlukile kakhulu wesimo se-"v" okwenza siqine emanzini futhi kube lula ukuqonda indlela yaso. Ngaphezu kwalokho, sisebenzisa izinto ze-carbon fiber ukwenza igobolondo liqine kakhudlwana, okunciphisa isisindo futhi kwandise ijubane lesikebhe. Isakhiwo sesikebhe sekristalu se-silicon carbide naso siwusizo kakhulu, sisebenzisa imishini ehlukahlukene kagesi, singathuthukisa ngempumelelo ukuphepha komkhumbi kanye nekhono lokuhamba.
Ukuhamba kwesikebhe se-SIC crystal nakho kuyinzuzo yaso eyingqayizivele. Sisebenzisa ubuchwepheshe obuningi obuhlakaniphile obungathuthukisa ngempumelelo ukusebenza kokuphathwa kwesikebhe, okwenza sikhululeke kakhulu emanzini futhi kube lula ukusiqondisa. Ngaphezu kwalokho, singafakelwa uhlelo lokuqhuba i-carbon fiber, okuthuthukisa kakhulu isivinini sokuhamba kanye nokuqina komkhumbi.
Ngamafuphi, isikebhe sekristalu se-silicon carbide siwuhlobo olusha lomkhumbi, sisebenza kahle kakhulu, sibukeka ngendlela ehlukile, siyakwazi ukujika kalula njalo njalo. Asikwazi nje ukuhlangabezana nokusetshenziswa kwansuku zonke kwezikebhe ezivamile, kodwa futhi singasetshenziswa emisebenzini efana nokugijima nokudubula, okuhlinzeka ngokuzijabulisa okwengeziwe kwezemidlalo zasemanzini.
