Kwimeko yemizi-mveliso ephuhlayo namhlanje, ukusetyenziswa kweiiseramics eziphambilinjengei-silicon carbide ceramicsiya isiba yinto eqhelekileyo. Ezi zixhobo zingeyiyo isinyithi, kubandakanywa iiseramics ze-silicon nitride, iiseramikhi ze-alumina kunye nezinye izinto eziguquguqukayo eziphambili, ziguqula imimandla eyahlukeneyo ngeempawu zabo eziphezulu kunye nezicelo ezahlukeneyo.
Enye yeendawo ezingundoqo apho iiseramikhi eziphucukileyo zinempembelelo enkulu kukuhlanjwa kwemigodi yamalahle kunye namashishini othutho. Phakathi kwazo, i-cyclone lining kunye ne-pipe lining yenziwe nge-alumina ceramics kunye ne-silicon carbide ceramics, ephucula ngokufanelekileyo ubomi obunganyangekiyo besixhobo. Oku akuphuculi kuphela ukuqina koomatshini, kodwa kunceda ukuphucula ukusebenza kakuhle kunye nokugcina iindleko.
Ukongeza, ukuguquguquka kweekeramics eziqhubela phambili kunabela kwizicelo ezichanekileyo kuwo wonke amashishini amaninzi. I-Silicon nitride ceramic kunye ne-zirconia ye-ceramic echanekileyo iinxalenye ze-ceramic zisetyenziswa ngokubanzi ngenxa yokusebenza kwazo okugqwesileyo kwiindawo ezibuhlungu. Ubunzima bayo obukhethekileyo, ukuzinza kwe-thermal kunye nokumelana nokubola kwenza kube yinto efanelekileyo yokusetyenziswa kumacandelo abalulekileyo apho ukuthembeka kunye nokuchaneka kubalulekile.
Kwicandelo lemveliso, ukusetyenziswa kweekeramics eziphambili kuvula amathuba amatsha okuphucula umgangatho wemveliso kunye nokusebenza. I-silicon carbide ceramics, ngokukodwa, isetyenziswa ngokubanzi ngenxa ye-conductivity egqwesileyo ye-thermal kunye nokumelana nokutshatyalaliswa kwe-thermal. Oku kubenza baxabiseke kakhulu kwizicelo ezifana nokushisa okuphezulu, apho izinto zendabuko ziyakwazi ukungazinzi phantsi kweemeko ezinzima.
Ukongeza, i-aerospace kunye nemizi-mveliso yeemoto nayo iyaxhamla kwiiseramikhi eziphambili. Iiceramics ze-silicon nitride zinika amandla aphezulu kunye nokuchasana nokothuka kwe-thermal kwaye zisetyenziswa ngokubanzi kumacandelo enjini, iinkqubo ezisikwayo zokuqhubela phambili kunye netekhnoloji ye-braking ephezulu. Oku akugxininisi kuphela ukulungelelaniswa kweekeramics eziphambili, kodwa kunye nendima yazo ebalulekileyo ekuqhubeni izinto ezintsha kunye nenkqubela phambili kule mimandla yobuchwepheshe obuphezulu.
Ngokufutshane, ukwamkelwa okuxhaphakileyo kweeseramics eziphambili ezinje ngesilicon carbide ceramics, isilicon nitride ceramics, kunye neekeramics zealumina kubumba kwakhona ubume beshishini. Ukusuka ekuphuculeni ukuqina kwezixhobo kwimisebenzi yokomba amalahle ukuya ekuvumeleni ubunjineli obuchanekileyo kwiinkalo ezahlukeneyo, ezi mathiriyeli zibonakala ziyimfuneko. Njengoko imizi-mveliso iqhubeleka nokutyhala imida yokusebenza kunye nempumelelo, iiseramikhi eziphucukileyo ngokungathandabuzekiyo ziya kuhlala ziphambili kwinguqulelo entsha, ukuqhuba inkqubela kunye nokubumba ikamva leshishini langoku.
