Esimweni sezimboni esithuthuka ngokushesha, ukusetshenziswa kwei-ceramics ethuthukisiwenjengei-silicon carbide ceramicskuya ngokuya kuvama. Lezi zinto ezingezona ezensimbi, okuhlanganisa izitsha zobumba ze-silicon nitride, izitsha zobumba ze-alumina nezinye izinhlobo ezithuthukisiwe, zishintsha imikhakha ehlukahlukene ngezakhiwo zazo eziphakeme kanye nokusetshenziswa okuhlukahlukene.
Enye yezindawo ezibalulekile lapho izitsha zobumba ezithuthukisiwe zinomthelela omkhulu kusezimbonini zokuwasha kanye nezokuthutha ezimayini zamalahle. Phakathi kwazo, i-cyclone lining kanye ne-pipe lining yenziwe nge-alumina ceramics kanye ne-silicon carbide ceramics, ethuthukisa ngempumelelo impilo yokumelana nokugqokwa kwemishini. Lokhu akuthuthukisi kuphela ukuqina kwemishini, kodwa futhi kusiza ukuthuthukisa ukusebenza kahle nokusebenza kahle futhi konga izindleko.
Ukwengeza, ukuhlukahluka kwezitsha zobumba ezithuthukisiwe kudlulela ekusetshenzisweni okunembayo kuzo zonke izimboni eziningi. Izingxenye ze-Silicon nitride ceramic kanye ne-zirconia ceramic precision izingxenye zisetshenziswa kabanzi ngenxa yokusebenza kwazo okuhle kakhulu ezindaweni ezinokhahlo. Ukuqina kwayo okungavamile, ukuzinza kokushisa nokumelana nokugqwala kuyenza ifaneleke ukusetshenziswa ezingxenyeni ezibucayi lapho ukwethembeka nokunemba kubaluleke khona.
Emkhakheni wokukhiqiza, ukusetshenziswa kwezitsha zobumba ezithuthukisiwe kuvula amathuba amasha okuthuthukisa izinga lomkhiqizo nokusebenza. I-silicon carbide ceramics, ikakhulukazi, isetshenziswa kabanzi ngenxa ye-thermal conductivity enhle kakhulu kanye nokumelana nokushisa okushisayo. Lokhu kubenza babe yigugu ezinhlelweni zokusebenza ezifana nokucubungula izinga lokushisa eliphezulu, lapho izinto zendabuko zingase zingazinzi ngaphansi kwezimo ezimbi kakhulu.
Ngaphezu kwalokho, izimboni ze-aerospace nezezimoto nazo ziyazuza kuma-ceramics athuthukile. I-Silicon nitride ceramics inikeza amandla aphezulu kanye nokumelana nokushaqeka okushisayo futhi isetshenziswa kabanzi ezingxenyeni zenjini, ama-cutting-edge propulsion systems kanye nobuchwepheshe obuphambili bokubhuleka. Lokhu akugcizeleli nje kuphela ukuguquguquka kwezitsha zobumba ezithuthukisiwe, kodwa futhi nendima yazo ebalulekile ekushayeleni emisha kanye nenqubekelaphambili kule mikhakha yobuchwepheshe obuphezulu.
Ngamafuphi, ukwamukelwa okusabalele kwezitsha zobumba ezithuthukisiwe ezifana ne-silicon carbide ceramics, i-silicon nitride ceramics, kanye ne-alumina ceramics kwakheka kabusha indawo yezimboni. Kusukela ekuthuthukiseni ukuqina kwemishini emisebenzini yokumba amalahle kuya ekuvumela ubunjiniyela obunembayo emikhakheni eyahlukene, lezi zinto zokusebenza zibonakala zibalulekile. Njengoba izimboni ziqhubeka nokuphusha imingcele yokusebenza nokusebenza kahle, izitsha zobumba ezithuthukisiwe ngokungangabazeki zizohlala zihamba phambili ekusungulweni okusha, okuqhubekisela phambili inqubekelaphambili kanye nokulolonga ikusasa lemboni yesimanje.
