Kafufuzidwe kafukufuku wa silicon carbide ceramics wopangidwanso

Recrystallizedsilicon carbide (RSiC) ceramicsndi azida za ceramic zogwira ntchito kwambiri. Chifukwa cha kukana kwambiri kutentha kwapamwamba, kukana kwa okosijeni, kukana kwa dzimbiri komanso kuuma kwakukulu, kwagwiritsidwa ntchito kwambiri m'magawo ambiri, monga kupanga semiconductor, mafakitale a photovoltaic, ng'anjo zotentha kwambiri ndi zida zamankhwala. Chifukwa cha kuchuluka kwa zinthu zomwe zimagwira ntchito kwambiri m'makampani amakono, kafukufuku ndi chitukuko cha zoumba zowumbidwanso za silicon carbide zikukula.

1. Kukonzekera luso larecrystallized silicon carbide ceramics
The luso kukonzekera recrystallizedsilicon carbide ceramicsmakamaka zikuphatikizapo njira ziwiri: ufa sintering ndi nthunzi deposition (CVD). Pakati pawo, njira yopangira ufa ndikuyika silicon carbide ufa pansi pa kutentha kwakukulu kuti tinthu tating'onoting'ono ta silicon carbide tipange mawonekedwe owundana kudzera mu kufalikira ndi kukonzanso pakati pa mbewu. Njira yoyika nthunzi ndikuyika silicon carbide pamwamba pa gawo lapansi kudzera mu nthunzi wamankhwala pa kutentha kwakukulu, potero kupanga filimu yoyera kwambiri ya silicon carbide kapena zigawo zamapangidwe. Matekinoloje awiriwa ali ndi ubwino wawo. Njira yopangira ufa ndiyoyenera kupanga zazikulu ndipo imakhala yotsika mtengo, pomwe njira yoyika nthunzi imatha kupereka chiyero chapamwamba komanso mawonekedwe owoneka bwino, ndipo imagwiritsidwa ntchito kwambiri m'munda wa semiconductor.

2. Zinthu zakuthupi zarecrystallized silicon carbide ceramics
Makhalidwe abwino kwambiri a silicon carbide ceramics of recrystallized silicon carbide ceramics ndi ntchito yake yabwino kwambiri m'malo otentha kwambiri. Malo osungunuka a zinthuzi ndi okwera kwambiri mpaka 2700 ° C, ndipo ali ndi mphamvu zamakina abwino pa kutentha kwakukulu. Kuphatikiza apo, recrystallized silicon carbide imakhalanso ndi kukana kwa okosijeni wabwino kwambiri komanso kukana kwa dzimbiri, ndipo imatha kukhala yokhazikika m'malo opangira mankhwala. Chifukwa chake, zoumba za RSiC zakhala zikugwiritsidwa ntchito kwambiri popanga ng'anjo zotentha kwambiri, zida zowotchera kutentha kwambiri, ndi zida zamagetsi.

Kuphatikiza apo, recrystallized silicon carbide imakhala ndi matenthedwe apamwamba kwambiri ndipo imatha kuyendetsa bwino kutentha, zomwe zimapangitsa kuti ikhale yofunika kugwiritsa ntchito.MOCVD reactorndi zida zochizira kutentha pakupanga semiconductor wafer. Kuthamanga kwake kwapamwamba kwa kutentha ndi kutentha kwa kutentha kumatsimikizira kuti zipangizozi zimagwira ntchito modalirika kwambiri.

3. Ntchito minda ya recrystallized silicon carbide ceramics

Kupanga kwa semiconductor: M'makampani opangira semiconductor, zoumba za silicon carbide zowonjezeredwa zimagwiritsidwa ntchito popanga magawo ndi zothandizira mu MOCVD reactors. Chifukwa cha kukana kwake kutentha kwambiri, kukana kwa dzimbiri, komanso kutulutsa kwamafuta ambiri, zida za RSiC zimatha kukhazikika m'malo ovuta kuchitapo kanthu, kuwonetsetsa kuti ma semiconductor wafers ndi abwino komanso zokolola.

Makampani a Photovoltaic: M'makampani a photovoltaic, RSiC imagwiritsidwa ntchito popanga mawonekedwe othandizira a zida za kukula kwa kristalo. Popeza kukula kwa kristalo kuyenera kuchitika pa kutentha kwakukulu panthawi yopanga maselo a photovoltaic, kukana kutentha kwa recrystallized silicon carbide kumatsimikizira kuti zidazo zimagwira ntchito kwa nthawi yaitali.

Ng'anjo zotentha kwambiri: Zoumba za RSiC zimagwiritsidwanso ntchito kwambiri m'ng'anjo zotentha kwambiri, monga ng'anjo ndi zida za vacuum, ng'anjo zosungunuka ndi zida zina. Kulimbana kwake ndi kutentha kwamphamvu komanso kukana kwa okosijeni kumapangitsa kuti ikhale imodzi mwazinthu zosasinthika m'mafakitale otentha kwambiri.

4. Kafufuzidwe kafukufuku wa recrystallized silicon carbide ceramics
Pakuchulukirachulukira kwa zida zogwira ntchito kwambiri, njira yofufuzira yopangira zitsulo za silicon carbide ceramics pang'onopang'ono ikuwonekera. Kafukufuku wamtsogolo adzayang'ana mbali zotsatirazi:

Kupititsa patsogolo chiyero chakuthupi: Pofuna kukwaniritsa zofunikira zaukhondo mu semiconductor ndi photovoltaic fields, ofufuza akufufuza njira zowonjezera chiyero cha RSiC pokonza teknoloji yoyika mpweya kapena kuyambitsa zipangizo zatsopano, potero kupititsa patsogolo ntchito yake m'madera apamwambawa. .

Kukhathamiritsa microstructure: Poyang'anira sintering mikhalidwe ndi kugawa tinthu ufa, ndi microstructure wa recrystallized pakachitsulo carbide akhoza zina wokometsedwa, potero kusintha makina ake katundu ndi matenthedwe kukana mantha.

Zida zogwirira ntchito: Kuti agwirizane ndi malo ovuta kwambiri ogwiritsira ntchito, ofufuza akuyesera kuphatikiza RSiC ndi zipangizo zina kuti apange zipangizo zophatikizika ndi zinthu zambiri, monga silicon carbide-based composite materials ndi kukana kwapamwamba kuvala ndi ma conductivity magetsi.

5. Mapeto
Monga zinthu zogwira ntchito kwambiri, zoumba za silicon carbide zowonjezeredwa zakhala zikugwiritsidwa ntchito kwambiri m'magawo ambiri chifukwa cha zinthu zabwino kwambiri pakutentha kwambiri, kukana kwa okosijeni komanso kukana dzimbiri. Kafukufuku wamtsogolo adzayang'ana kwambiri pakuwongolera kuyera kwazinthu, kukhathamiritsa ma microstructure ndikupanga zida zogwirira ntchito kuti zikwaniritse zosowa zamakampani zomwe zikukula. Kudzera muzatsopano zaukadaulo izi, zowumbidwanso za silicon carbide ceramics zikuyembekezeka kutenga gawo lalikulu m'magawo apamwamba kwambiri.
