Kumbuyo kwa kupita patsogolo kwaukadaulo pakuchaja mwachangu magalimoto atsopano amphamvu komanso injini zoyendetsa ndege zogwira ntchito bwino, pali chinthu chowoneka ngati chachilendo koma champhamvu -zoumbaumba za silicon carbideChomera chapamwamba ichi chopangidwa ndi zinthu za kaboni ndi silicon, ngakhale sichimakambidwa kawirikawiri monga tchipisi ndi mabatire, chakhala "ngwazi yobisika" m'magawo ambiri apamwamba chifukwa cha magwiridwe ake "olimba".
Khalidwe lodziwika bwino la silicon carbide ceramics ndi "kusinthasintha kwawo kwamphamvu kwambiri" kumadera ovuta kwambiri. Zipangizo wamba zimatha kuwonongeka kwambiri pa kutentha kwambiri, mofanana ndi "kulephera kwa heatstroke", koma zimatha kusungabe mphamvu zoposa 80% ngakhale pa 1200 ℃, ndipo zimatha kupirira kukhudzidwa kwakukulu kwa 1600 ℃ kwakanthawi kochepa. Kukana kutentha kumeneku kumapangitsa kuti izionekera bwino pazochitika zotentha kwambiri, monga kukhala chinthu chofunikira kwambiri pazigawo zotentha za injini za ndege. Nthawi yomweyo, kuuma kwake ndi kwachiwiri kwa diamondi, ndi kuuma kwa Mohs kwa 9.5. Kuphatikiza ndi kukana dzimbiri kwabwino, imatha kukhala yokhazikika m'malo amphamvu a asidi ndi alkali, ndipo nthawi yake yogwirira ntchito imaposa kwambiri zida zachikhalidwe zachitsulo.
Mu gawo la magetsi ndi kasamalidwe ka kutentha, ma silicon carbide ceramics awonetsa makhalidwe a "wosewera wozungulira". Kutenthetsa kwake kuli kofanana ndi ma ceramics achikhalidwe a alumina, zomwe zikufanana ndi kukhazikitsa "chotenthetsera chogwira ntchito bwino" pazida zamagetsi, chomwe chingachotse mwachangu kutentha komwe kumapangidwa panthawi yogwira ntchito ya zida.
Masiku ano, kupezeka kwa silicon carbide ceramics kwafalikira m'magawo ambiri ofunikira. Mu magalimoto atsopano amphamvu, imabisika mu gawo lamagetsi, zomwe zimafupikitsa nthawi yochaja komanso kutalika kwake; Mu gawo la ndege, zida za turbine zopangidwa kuchokera pamenepo zimatha kuchepetsa kulemera kwa zida ndikuwonjezera mphamvu; Pakupanga ma semiconductor, mawonekedwe ake otsika a kutentha amapangitsa zida zolondola monga makina a lithography kukhala zolondola komanso zokhazikika; Ngakhale m'makampani opanga zida za nyukiliya, yakhala chinthu chofunikira kwambiri pakupanga ma reactor chifukwa cha mphamvu yake yolimbana ndi ma radiation.
Kale, mtengo unali chopinga pakufalikira kwa zinthu za silicon carbide ceramics, koma chifukwa cha kukhwima kwa ukadaulo wokonzekera, mtengo wake watsika pang'onopang'ono, ndipo mafakitale ambiri akuyamba kusangalala ndi phindu la kusinthaku kwa zinthu. Kuyambira magalimoto amagetsi oyendera tsiku ndi tsiku mpaka zombo zoyendera mlengalenga, zinthu "zolimba" izi zomwe zikuwoneka ngati zosawoneka bwino zikuyendetsa ukadaulo kupita ku tsogolo labwino komanso lodalirika m'njira yotsika koma yamphamvu.
