Mu gawo la kupanga mafakitale, zipangizo zadothi zikulemba nthano yatsopano. Mosiyana ndi zombo zadothi zomwe zimachitika tsiku ndi tsiku, zombo zadothi za mafakitale zawonetsa magwiridwe antchito awo abwino kwambiri m'magawo ofunikira monga zitsulo, uinjiniya wa mankhwala, ndi mphamvu zatsopano. Aluminium oxide, silicon nitride, zirconium oxide ndi zipangizo zina zili ndi makhalidwe awoawo, koma pankhani ya mphamvu yamphamvu kwambiri ya "wosewera wozungulira",zoumbaumba za silicon carbidemosakayikira ndi abwino kwambiri.
Zida za alumina zili ngati amisiri achikhalidwe, odziwika ndi kuuma kwawo kwakukulu komanso mtengo wake wotsika, koma nthawi zambiri amavutika ndi kutentha kwambiri. Zida za silicon nitride, monga zida zolondola, zimakhala ndi kukana kutentha kwambiri, koma zimatha kuwonetsa "nthiti zofewa" m'malo ena owononga. Zida za zirconia zili ngati asilikali apadera, odziwika ndi kulimba kwawo kwakukulu, koma amatha "kupuma pantchito" kumayambiriro kwa nkhondo yotentha komanso yayitali.
Mosiyana ndi zimenezi, zinthu zomangira za silicon carbide zasonyeza mphamvu zodabwitsa. Chipangizo cha kristalo ichi, chomwe chimapangidwa mwamphamvu ndi maatomu a silicon carbon, chili ndi ubwino waukulu wa zinthu zitatu: kutentha kwake kwamphamvu kwambiri kumachipangitsa kukhala "chete" m'malo otentha kwambiri, kukana kwake kuvala bwino kwambiri kumachipangitsa kukhala "cholimba mtima kwambiri" m'malo ovuta kugwira ntchito, ndipo kukhazikika kwake kwapadera kwa mankhwala kuli ngati chishango chachilengedwe choteteza, cholimbana ndi kuukira kwa zinthu zosiyanasiyana zowononga.
Pankhani yoyang'anira kutentha, mphamvu ya kutentha ya silicon carbide ceramics ndi katatu kuposa ya chitsulo wamba. "Talente yoyatsira kutentha" iyi imapangitsa kuti ikhale chisankho chabwino kwambiri cha ma uvuni otentha kwambiri komanso ma semiconductor substrates. Poyang'anizana ndi vuto la kuwonongeka, kuuma kwake pamwamba ndi kwachiwiri kuposa diamondi, zomwe zimasonyeza moyo wautali kwambiri pazochitika monga makina amigodi ndi mapaipi oyendera. Chosowa kwambiri ndichakuti chipangizochi chimatha kusunga mtundu wake wachilengedwe ngakhale m'malo owononga monga ma acid amphamvu, zomwe zimagwirizana bwino ndi zosowa zapadera za zida zamakemikolo.
Ndi chitukuko champhamvu cha makampani atsopano opanga mphamvu, ziwiya za silicon carbide zikutsegula madera atsopano ogwiritsira ntchito. Pankhani yopanga mphamvu ya photovoltaic, imakhala chinthu chabwino kwambiri chothandizira kupirira nyengo; Pa mzere wopanga batire ya lithiamu, yasinthidwa kukhala mbale zopyapyala zolondola kwambiri. Mphamvu iyi ya "kudutsa malire" imachokera ku kuphatikiza kwake kwapadera - imatha kupirira kutentha kwa 1350 ℃ ndikugwira ntchito mokhazikika m'malo ozizira kwambiri a -60 ℃.
Monga akatswiri aukadaulo omwe amagwira ntchito kwambiri mu ntchito ya silicon carbide ceramics, nthawi zonse timakonza bwino njira zopangira zinthu ndi njira zoyeretsera, pamene tikusunga ubwino wathu wachikhalidwe, nthawi zonse timawongolera mphamvu ya makina ndi kulondola kwa zinthu. Kudzera mu ma ratios enieni a zinthu zopangira ndi ukadaulo watsopano woyeretsera, zinthu zathu zasintha kwambiri kudalirika pansi pa zovuta zogwirira ntchito, zomwe zimapereka chitsimikizo cholimba cha zinthu zamagetsi zamakono.
Kusankha zipangizo zadothi za mafakitale kwenikweni kumafuna mgwirizano pakati pa magwiridwe antchito ndi mtengo. Zida zadothi za silicon carbide, zomwe zili ndi ubwino wake wokwera mtengo, zikukonzanso miyezo yopangira mafakitale - kuchepetsa kuchuluka kwa zinthu zomwe zimasinthidwa ndi moyo wautali, kuchepetsa ndalama zokonzera ndi magwiridwe antchito okhazikika, komanso kupangitsa kuti kusankha zida kukhale kosavuta pogwiritsa ntchito njira zosiyanasiyana. Ichi chikhoza kukhala chifukwa chachikulu chomwe mainjiniya ambiri akuziika pamndandanda wazinthu zomwe amakonda.
Tikamalankhula za kupita patsogolo kwa mafakitale, kupanga zinthu zatsopano nthawi zambiri kumakhala chinthu chofunikira kwambiri komanso chofunikira kwambiri. Kusintha kosalekeza kwa ziwiya za silicon carbide sikuti kumangoyimira kupita patsogolo kwa ukadaulo wa ziwiya za ceramic, komanso kumabweretsa kusintha kwina pakupanga bwino mafakitale. Munthawi ino yofunafuna magwiridwe antchito apamwamba, ziwiya za ceramic "zoganiza" izi zikutsegula malo atsopano oganiza bwino opangira zinthu zamakono.
