Emva kwempumelelo yetekhnoloji ekutshajeni ngokukhawuleza kwezithuthi ezintsha zamandla kunye neenjini zeenqwelo moya ezisebenzayo ngakumbi, kukho into ebonakala iqhelekile kodwa enamandla –iiseramikhi zesilicon carbideLe ceramic iphucukileyo eyenziwe ngezinto zekhabhoni kunye nesilicon, nangona ingathethwa rhoqo njengeetships kunye neebhetri, ibe "yiqhawe elifihliweyo" kwiindawo ezininzi eziphezulu ngenxa yokusebenza kwayo "okuqinileyo".
Eyona nto ibalulekileyo kwiiseramikhi ze-silicon carbide kukuba “ziyakwazi ukuzivumelanisa nezimo” kwiindawo ezishushu kakhulu. Izixhobo eziqhelekileyo zinokonakala xa zisebenza kumaqondo obushushu aphezulu, okufana “nokungaphumeleli kwe-heatstroke”, kodwa zisenokugcina amandla azo angaphezu kwama-80% nokuba zikwi-1200 ℃, kwaye zinokumelana nemiphumo emibi kakhulu ye-1600 ℃ kwixesha elifutshane. Olu xhathiso lobushushu luyenza ibonakale kwiimeko zobushushu obuphezulu, njengokuba yinto ephambili kwizinto ezishushu zeenjini zeenqwelo-moya. Kwangaxeshanye, ubunzima bayo bulandela idayimani kuphela, bunobunzima be-Mohs obuyi-9.5. Idibene nokumelana nokugqwala okugqwesileyo, inokugcina uzinzo kwiindawo ezishushu ze-asidi kunye ne-alkali, kwaye ubomi bayo benkonzo budlula kakhulu izinto zesinyithi zemveli.
Kwimimandla yombane kunye nolawulo lobushushu, ii-silicon carbide ceramics zibonakalise iimpawu "zomdlali ojikelezayo". Ukuqhuba kwayo ubushushu kuphindwe kaninzi kunokwe-alumina ceramics zemveli, okufana nokufaka "isinki yobushushu esebenzayo" kwizixhobo ze-elektroniki, ezinokususa ngokukhawuleza ubushushu obuveliswa ngexesha lokusebenza kwezixhobo.
Kule mihla, ubukho bee-silicon carbide ceramics busasazeke kwiindawo ezininzi ezibalulekileyo. Kwizithuthi ezintsha zamandla, ifihliwe kwimodyuli yamandla, inciphisa ixesha lokutshaja kwaye inwebe uluhlu; Kwintsimi yeenqwelo-moya, izinto ze-turbine ezenziwe ngayo zinokunciphisa ubunzima bezixhobo kwaye zonyuse ukutyhala; Kwimveliso ye-semiconductor, iimpawu zayo zokwandiswa kobushushu obuphantsi zenza izixhobo ezichanekileyo ezifana noomatshini be-lithography zichaneke ngakumbi kwaye zizinzile; Kwanakwishishini lenyukliya, iye yaba yinto ebalulekileyo yokwakha ii-reactors ngenxa yenzuzo yayo yokumelana nemisebe.
Ngaphambili, ixabiso lalingumqobo ekuthandeni ukuthandwa kwee-silicon carbide ceramics, kodwa ngokuvuthwa kwetekhnoloji yokulungiselela, ixabiso layo liye lehla kancinci kancinci, kwaye amashishini amaninzi aqala ukonwabela iinzuzo zolu tshintsho lwezinto eziphathekayo. Ukususela kwizithuthi zombane zokuhamba imihla ngemihla ukuya kwi-spacecraft yokuhlola isithuba, le nto "ithambo eliqinileyo" ebonakala ingabonakali iqhuba itekhnoloji ukuya kwikamva elisebenzayo nelinokuthenjwa ngendlela ethobekileyo kodwa enamandla.
