1, Yogwiritsidwa ntchito pa zipangizo zamtengo wapatali
Mu makampani opanga miyala yamtengo wapatali, silicon carbide imadziwikanso kuti "moissanite". Zipangizo zomwe zimapezeka pamsika zimapangidwa ndi moissanite yopangidwa mwaluso, pomwe moissanite yachilengedwe ndi yosowa kwambiri, yosowa kwambiri kotero kuti imapezeka m'mabowo a meteorite zaka 50000 zapitazo.
2, ntchito zachikhalidwe zamafakitale
Mu gawo lachikhalidwe la mafakitale, silicon carbide imagwiritsidwa ntchito makamaka ngati chinthu chotsutsa, chida chokwirira, komanso ngati zinthu zopangira zitsulo, zomwe zidzasanthulidwa padera m'malemba otsatirawa.
(1) Zinthu zotsutsana ndi kutentha kwambiri:
Pogwiritsa ntchito makhalidwe a kukana dzimbiri, kukana kutentha kwambiri, mphamvu zambiri, kutentha kwabwino, komanso kukana mphamvu kwa zinthu za silicon carbide, zingagwiritsidwe ntchito pazitseko zosiyanasiyana za ng'anjo yosungunulira, zigawo za ng'anjo yosungunulira kutentha kwambiri, mbale za silicon carbide, mbale za lining, zothandizira, ndi ma ladle. Kumbali ina, zipangizo zotenthetsera zosalunjika kutentha kwambiri zingagwiritsidwe ntchito mumakampani osungunulira zitsulo zosapanga chitsulo, monga ziwiya zoyezera zoyima, mbale za arc za zinc powder furnaces, machubu oteteza thermocouple, ndi zina zotero; Amagwiritsidwa ntchito popanga zipangizo zapamwamba za silicon carbide ceramic zomwe sizimawonongeka, sizimawonongeka, komanso sizimatentha kwambiri; Ingagwiritsidwenso ntchito popanga ma nozzles a rocket, masamba a gasi turbine, ndi zina zotero. Kuphatikiza apo, silicon carbide ndi imodzi mwa zipangizo zabwino kwambiri zotenthetsera madzi a dzuwa pamisewu ikuluikulu, njira zoyendera ndege, ndi zina zotero. Chifukwa chake, silicon carbide ilinso ndi dzina lodziwika bwino la "mchenga wosasunthika", womwe, ngakhale uli wofala kwambiri, umasonyeza bwino momwe umakhalira wosasunthika.
(2) Zogulitsa zoteteza kuvala komanso zoteteza dzimbiri:
Makamaka chifukwa chakuti silicon carbide ili ndi kuuma kwakukulu, ndi kuuma kwa Mohs kwa 9.2-9.8, yachiwiri pambuyo pa diamondi yolimba kwambiri padziko lonse lapansi (level 10), imadziwika kuti "mchenga wagolide". Ilinso ndi kukhazikika kwabwino kwa mankhwala komanso kulimba kwina, ndipo ingagwiritsidwe ntchito kupanga mawilo opukutira, mapepala a sandpaper, malamba amchenga, miyala yamafuta, mabuloko opukutira, mitu yopukutira, ma phala opukutira, komanso popukutira ndi kupukuta monocrystalline silicon, polycrystalline silicon, ndi ma piezoelectric crystals mumakampani amagetsi pazinthu zamagetsi.
(3) Zipangizo zopangira zitsulo:
Silicon carbide ingagwiritsidwe ntchito ngati deoxidizer popanga zitsulo komanso chosinthira kapangidwe ka chitsulo chosungunuka. Ingagwiritsidwenso ntchito ngati zopangira popanga silicon tetrachloride ndipo ndiye chinthu chachikulu chopangira utomoni wa silicone. Silicon carbide deoxidizer ndi mtundu watsopano wa deoxidizer wamphamvu wophatikizana womwe umalowa m'malo mwa ufa wachikhalidwe wa silicon ndi ufa wa carbon kuti uchotse oxidation. Poyerekeza ndi njira yoyambirira, ili ndi mphamvu zokhazikika komanso zamakemikolo, zotsatira zabwino za deoxidation, nthawi yochepa ya deoxidation, mphamvu yosungidwa, magwiridwe antchito abwino opangira zitsulo, khalidwe labwino la chitsulo, kugwiritsa ntchito zinthu zopangira zochepa, kuchepetsa kuipitsa chilengedwe, kusintha magwiridwe antchito, komanso phindu lalikulu lachuma la uvuni zamagetsi, zonse zomwe zili ndi phindu lofunikira.
3, Silicon carbide kuwala kuwala kuwala
Zipangizo za ceramic zopangidwa pogwiritsa ntchito ntchito zapadera za ceramic pankhani ya zinthu zakuthupi monga phokoso, kuwala, magetsi, maginito, ndi kutentha zimatchedwa functional ceramics. Pali mitundu yosiyanasiyana ya functional ceramics yomwe imagwiritsidwa ntchito mosiyanasiyana, ndipo silicon carbide imagwiritsidwa ntchito makamaka ngati galasi lowunikira m'munda wa functional ceramics. SiC ceramics ili ndi kuuma kwapadera, kutentha bwino komanso kukhazikika kwa mankhwala, kutentha kochepa, komanso kukana kuwala kwa tinthu tating'onoting'ono ta malo. Kudzera mu njira zapadera zopangira, matupi opepuka a magalasi amatha kupezeka.
4, Monga zinthu za semiconductor
Semiconductor ya m'badwo wachitatu ndi chinthu chofunikira kwambiri pakupanga zinthu zatsopano, chitukuko, kusintha ndi kukweza zida zankhondo zodzitetezera kudziko, kulumikizana kwa mafoni a 5G, intaneti yamagetsi, magalimoto atsopano amphamvu, mayendedwe a sitima ndi mafakitale ena. Chifukwa cha ntchito yake yofunika kwambiri pachitetezo cha dziko, kupanga zinthu mwanzeru, kukweza mafakitale, kusunga mphamvu ndi kuchepetsa utsi ndi zosowa zina zazikulu zankhondo, ikukhala malo opikisana kwambiri padziko lonse lapansi.
SiC, monga choyimira wamba cha zipangizo za semiconductor za m'badwo wachitatu, pakadali pano ndi imodzi mwa zipangizo za semiconductor zokhwima kwambiri komanso zogwiritsidwa ntchito kwambiri muukadaulo wopanga makristalo ndi kupanga zida. Yapanga unyolo wapadziko lonse wazinthu, zida, ndi ntchito. Ndi zipangizo zabwino kwambiri za semiconductor zogwiritsidwa ntchito kutentha kwambiri, pafupipafupi kwambiri, kukana ma radiation, komanso mphamvu zambiri. Chifukwa cha kuchepa kwakukulu kwa kugwiritsa ntchito mphamvu kwa zida zamagetsi, zida zamagetsi za silicon carbide zimadziwikanso kuti "zipangizo zamagetsi zobiriwira" zomwe zimayendetsa "kusintha kwatsopano kwa mphamvu".
5, Wothandizira Kulimbikitsa ndi Kulimbitsa
Kuwonjezera pa ntchito zomwe zili pamwambapa, ndevu za silicon carbide kapena ulusi wa silicon carbide zagwiritsidwa ntchito kwambiri ngati zinthu zabwino kwambiri zolimbitsa ndi kulimbitsa mu zipangizo zopangidwa ndi zitsulo kapena ceramic m'magawo monga makina, uinjiniya wa mankhwala, chitetezo cha dziko, mphamvu, ndi kuteteza chilengedwe.
