1. Amagwiritsidwa ntchito pazinthu zamtengo wapatali
M'makampani a miyala yamtengo wapatali, silicon carbide imadziwikanso kuti "moissanite". Zinthu zomwe zimawonedwa kwambiri pamsika ndizopangidwa mwaluso moissanite, pomwe moissanite zachilengedwe ndizosowa kwambiri, ndizosowa kwambiri kotero kuti zidangowonekera m'mabwinja a meteorite zaka 50000 zapitazo.
2, ntchito zamakampani zachikhalidwe
M'munda wamafakitale wamba, silicon carbide imagwiritsidwa ntchito makamaka ngati chida chotsutsa, chida cha abrasive, ndi zinthu zachitsulo, zomwe zidzawunikidwa padera m'malemba otsatirawa.
(1) Zopangira kutentha kwambiri:
Pogwiritsa ntchito mawonekedwe a kukana kwa dzimbiri, kukana kutentha kwambiri, kulimba kwamphamvu, kukhathamiritsa kwamafuta abwino, komanso kukana kwa zida za silicon carbide, zitha kugwiritsidwa ntchito popanga ng'anjo zosiyanasiyana zosungunula, zigawo za ng'anjo yotentha kwambiri, mbale za silicon carbide, mbale zomangira, zothandizira, ndi ma ladle. Kumbali ina, zida zotenthetsera zosalunjika zitha kugwiritsidwa ntchito m'makampani osungunula zitsulo zopanda chitsulo, monga ng'anjo zowongoka, mbale za arc za ng'anjo za ufa wa zinki, machubu oteteza thermocouple, ndi zina zambiri; Amagwiritsidwa ntchito popanga zida zapamwamba za silicon carbide ceramic zomwe sizimva kuvala, zosagwira dzimbiri, komanso zosagwira kutentha kwambiri; Ikhoza kugwiritsidwanso ntchito kupanga ma rocket nozzles, masamba a turbine a gasi, etc. Komanso, silicon carbide ndi imodzi mwa zipangizo zoyenera zopangira madzi otentha a dzuwa pa misewu, misewu ya ndege, ndi zina zotero.
(2) Zovala zosagwirizana ndi dzimbiri:
Makamaka chifukwa silicon carbide imakhala yolimba kwambiri, yokhala ndi kuuma kwa Mohs kwa 9.2-9.8, yachiwiri kwa diamondi yolimba kwambiri padziko lapansi (level 10), imadziwika kuti "mchenga wachitsulo chagolide". Ilinso ndi kukhazikika kwamankhwala abwino komanso kulimba kwina, ndipo angagwiritsidwe ntchito popanga mawilo akupera, sandpaper, malamba amchenga, miyala yamafuta, midadada akupera, mitu yopukutira, phala lopera, ndikupera ndi kupukuta silicon ya monocrystalline, silicon ya polycrystalline, ndi makhiristo a piezoelectric mumakampani opanga zamagetsi.
(3) Zopangira zitsulo:
Silicon carbide itha kugwiritsidwa ntchito ngati deoxidizer popanga zitsulo komanso chosinthira chachitsulo choponyedwa. Itha kugwiritsidwanso ntchito ngati zopangira zopangira silicon tetrachloride ndipo ndiye chinthu chachikulu chamakampani opanga utomoni wa silikoni. Silicon carbide deoxidizer ndi mtundu watsopano wa deoxidizer wamphamvu wamagulu omwe amalowa m'malo mwa ufa wa silicon ndi ufa wa kaboni wa deoxidation. Poyerekeza ndi ndondomeko yapachiyambi, imakhala ndi mphamvu zokhazikika zakuthupi ndi zamankhwala, zotsatira zabwino za deoxidation, kufupikitsa nthawi yowonongeka, mphamvu zopulumutsa, kupititsa patsogolo kupanga zitsulo, kupititsa patsogolo zitsulo, kuchepetsa kugwiritsidwa ntchito kwa zinthu zopangira, kuchepetsa kuwonongeka kwa chilengedwe, kupititsa patsogolo ntchito, ndi kupititsa patsogolo phindu lachuma la ng'anjo zamagetsi, zonse zomwe zili ndi phindu lofunika.
3, Silicon carbide kuwala reflector zakuthupi
Zida za ceramic zopangidwa pogwiritsa ntchito ntchito zapadera za ceramic potengera zinthu zakuthupi monga phokoso, kuwala, magetsi, maginito, ndi kutentha zimatchedwa zoumba zogwira ntchito. Pali mitundu yosiyanasiyana ya zoumba zogwirira ntchito zomwe zimagwiritsidwa ntchito mosiyanasiyana, ndipo silicon carbide imagwiritsidwa ntchito makamaka ngati kalirole wonyezimira pagawo lazoumba zogwira ntchito. Ma Ceramics a SiC ali ndi kuuma kwina kwapadera, kukhazikika kwamafuta komanso kukhazikika kwamankhwala, kutsika kwamafuta otsika, komanso kukana kuyatsa kwa tinthu ting'onoting'ono. Kupyolera mu njira zapadera zopangira, matupi agalasi opepuka amatha kupezeka.
4. Monga zida za semiconductor
Semiconductor ya m'badwo wachitatu ndi chinthu chofunikira kwambiri komanso gawo lamagetsi lomwe likuthandizira kukonzanso, chitukuko, kusintha ndi kukweza zida zachitetezo cha dziko, kulumikizana ndi mafoni a 5G, intaneti yamagetsi, magalimoto amagetsi atsopano, zoyendera njanji ndi mafakitale ena. Chifukwa cha gawo lake lofunikira pachitetezo chachitetezo cha dziko, kupanga mwanzeru, kukweza mafakitale, kusunga mphamvu ndi kuchepetsa utsi ndi zofunikira zina zazikulu, ikukhala malo otsogola pamipikisano padziko lonse lapansi.
SiC, monga woimira wachitatu m'badwo semiconductor zipangizo, panopa ndi mmodzi wa okhwima kwambiri ndi ambiri ntchito lonse bandgap semiconductor zipangizo luso kupanga galasi ndi kupanga zipangizo. Yapanga zinthu zapadziko lonse lapansi, zida, ndi unyolo wamakampani ogwiritsa ntchito. Ndi chida choyenera cha semiconductor cha kutentha kwambiri, ma frequency apamwamba, osamva ma radiation, komanso kugwiritsa ntchito mphamvu zambiri. Chifukwa cha kuchepa kwakukulu kwa kugwiritsa ntchito mphamvu zamagetsi zamagetsi, zida zamagetsi za silicon carbide zimadziwikanso kuti "zida zamagetsi zobiriwira" zomwe zikuyendetsa "kusintha kwamphamvu kwatsopano".
5, Kulimbikitsa ndi toughening wothandizira
Kuphatikiza pa zomwe tafotokozazi, ndevu za silicon carbide kapena ulusi wa silicon carbide zakhala zikugwiritsidwa ntchito kwambiri ngati zida zolimbikitsira komanso zolimba muzinthu zophatikizika ndi zitsulo zopangidwa ndi zitsulo kapena ceramic m'magawo monga makina, uinjiniya wamankhwala, chitetezo cha dziko, mphamvu, ndi kuteteza chilengedwe.
