Machitidwe a mafakitale otentha kwambiri amafuna zipangizo zomwe zimatha kupirira kutentha kwambiri, dzimbiri, ndi kutentha kwambiri popanda kuwononga magwiridwe antchito.Mapepala oletsa kukana a Silicon Carbide (SiC)Imaonekera ngati yankho labwino kwambiri, imapereka kulimba kosayerekezeka komanso kusinthasintha m'magawo ofunikira. Kuyambira pakupanga zitsulo mpaka zamagetsi ndi zoumbaumba, mbale izi ndizofunikira kwambiri pakukweza magwiridwe antchito, kuchepetsa nthawi yogwira ntchito, ndikukweza mtundu wa zinthu zomwe zimapangidwa - zomwe zimapangitsa kuti zikhale zofunikira kwambiri popanga zinthu zamakono zotentha kwambiri.
Kugwiritsira ntchito zitsulo ndi chimodzi mwa zinthu zofunika kwambiri zomwe zimagwiritsidwa ntchito popanga mbale zoyeretsera za silicon carbide. Mu aluminiyamu, zinc, ndi mkuwa, mbalezi zimagwiritsidwa ntchito ngati zoyikamo, zotsukira, ndi zida zothandizira mu uvuni ndi zovala. Kukana kwawo kwakukulu ku kuwonongeka kwa chitsulo chosungunuka ndi kutentha kwambiri (mpaka 1800°C) kumatsimikizira kuti nthawi yayitali ya ntchito imagwira ntchito, kuchepetsa kufunikira kosintha nthawi zambiri. Mosiyana ndi zipangizo zachikhalidwe zoyeretsera, mbale za SiC zimakhalanso ndi mphamvu yabwino kwambiri yoyendetsera kutentha, zomwe zimapangitsa kuti kutentha kugawikane mofanana komwe kumathandizira kuti kusungunuke kwachitsulo kukhale koyenera komanso kuchepetsa kugwiritsa ntchito mphamvu ndi 25%.
Makampani opanga zamagetsi ndi ma semiconductor amadalira kwambiri ma silicon carbide refractory plates kuti azitha kuchita bwino kwambiri kutentha. Pakupanga ma semiconductor, ma LED, ndi ma electronic ceramics, kuwongolera kuipitsidwa ndi kukhazikika kwa miyeso sikungatheke kukambirana. Ma SiC refractory plates ndi abwino kwambiri pano, chifukwa ndi osagwira ntchito mwa mankhwala ndipo amasunga mawonekedwe awo ngakhale atatenthedwa ndi kuzizira mobwerezabwereza. Amagwiritsidwa ntchito kwambiri popangira wafer annealing, chemical vapor deposition (CVD), komanso kuipitsa zinthu zamagetsi, zomwe zimathandiza opanga kuchepetsa zolakwika ndikuwonjezera kuchuluka kwa zokolola kwambiri.
Mu gawo la zinthu zopangira zinthu zadothi ndi zaukhondo, mbale zothira mafuta za silicon carbide zasintha kwambiri kupanga. Kaya ndi porcelain wouma, miyala, kapena zomatira zadothi za mafakitale, kukana kutentha kwambiri kwa mbalezi kumalepheretsa ming'alu kuti isasinthe kutentha mwachangu. Zimathandizanso kuti malo azikhala oyera komanso asamamatire, kusunga malo oyera ndikuchepetsa nthawi yokonza. Mafakitale adothi omwe amagwiritsa ntchito mbale zothira mafuta za SiC amanena kuti nthawi yayitali yogwira ntchito ndi 3-5 poyerekeza ndi mbale zachikhalidwe, komanso kusintha kwa 10-15% pamlingo woyenera wa zinthu - zabwino zazikulu zopangira zinthu zazikulu komanso zotsika mtengo.
Kupatula magawo ofunikira awa, mbale zoyeserera za silicon carbide zimagwiritsidwa ntchito mu mphamvu zongowonjezwdwa komanso mumlengalenga. Pakupanga mabatire a lithiamu-ion, amathandizira kuwotcha kwapamwamba kwa zinthu za cathode, kuonetsetsa kuti zinthuzo zimakhala zofanana. Mumlengalenga, amagwiritsidwa ntchito kuwotcha zigawo za ceramic zogwira ntchito bwino kwambiri zamainjini ndi ma avionics. Ndi kukula ndi mawonekedwe osinthika kuti zigwirizane ndi zosowa zosiyanasiyana za zida, mbale zoyeserera za SiC zimapereka magwiridwe antchito odalirika ogwirizana ndi zofunikira zina zamafakitale.
Kuyika ndalama mu mbale zoyezera kutentha za silicon carbide kumatanthauza kuyika ndalama mu ntchito yabwino kwa nthawi yayitali. Kuphatikiza kwawo kwapadera kolimbana ndi kutentha, kukana dzimbiri, komanso kuyendetsa bwino kutentha kumapangitsa kuti zikhale chisankho chotsika mtengo kwa mafakitale omwe cholinga chake ndi kukonza kukhazikika ndi kupanga bwino. Sinthani njira zanu zotenthetsera kwambiri lero ndi mbale zoyezera kutentha kwambiri za silicon carbide—komwe kulimba kumakwaniritsa magwiridwe antchito, komanso kudalirika kumayendetsa bwino.
