Kafukufuku wa momwe zinthu zopangira silicon carbide zobwezerezedwanso zimagwirira ntchito

Yopangidwansozoumba za silicon carbide (RSiC)ndizinthu zopangidwa ndi ceramic zogwira ntchito bwino kwambiriChifukwa cha kukana kutentha kwambiri, kukana okosijeni, kukana dzimbiri komanso kuuma kwambiri, yakhala ikugwiritsidwa ntchito kwambiri m'magawo ambiri, monga kupanga ma semiconductor, makampani opanga ma photovoltaic, uvuni wotentha kwambiri ndi zida zamakemikolo. Chifukwa cha kufunikira kwakukulu kwa zipangizo zogwira ntchito bwino m'makampani amakono, kafukufuku ndi chitukuko cha ziwiya za silicon carbide zobwezerezedwanso zikukulirakulira.

1. Ukadaulo wokonzekerazoumba za silicon carbide zowonjezeredwa

Ukadaulo wokonzekera zinthu zopangidwansozoumbaumba za silicon carbideMakamaka pali njira ziwiri: kusungunula ufa ndi kuyika nthunzi (CVD). Pakati pawo, njira yosungunula ufa ndiyo kusungunula ufa wa silicon carbide pansi pa kutentha kwambiri kuti tinthu ta silicon carbide tipange kapangidwe kolimba kudzera mu kufalikira ndi kubwezeretsanso pakati pa tirigu. Njira yosungunula nthunzi ndiyo kuyika silicon carbide pamwamba pa substrate kudzera mu nthunzi ya mankhwala kutentha kwambiri, motero kupanga filimu ya silicon carbide yoyera kwambiri kapena zigawo za kapangidwe kake. Maukadaulo awiriwa ali ndi ubwino wawo. Njira yosungunula ufa ndi yoyenera kupanga zinthu zambiri ndipo ndi yotsika mtengo, pomwe njira yosungunula nthunzi imatha kupereka kuyera kwambiri komanso kapangidwe kolimba, ndipo imagwiritsidwa ntchito kwambiri m'munda wa semiconductor.

2. Kapangidwe ka zinthu zazoumba za silicon carbide zowonjezeredwa

Khalidwe labwino kwambiri la zoumba za silicon carbide zobwezerezedwanso ndilakuti zimagwira ntchito bwino kwambiri m'malo otentha kwambiri. Kutentha kwa zinthuzi kumafika pa 2700°C, ndipo zimakhala ndi mphamvu yabwino yamakina pa kutentha kwambiri. Kuphatikiza apo, silicon carbide yobwezerezedwanso imakhala ndi kukana kwabwino kwa okosijeni komanso kukana dzimbiri, ndipo imatha kukhalabe yokhazikika m'malo oopsa kwambiri a mankhwala. Chifukwa chake, zoumba za RSiC zakhala zikugwiritsidwa ntchito kwambiri m'minda ya ng'anjo zotentha kwambiri, zinthu zotsutsana ndi kutentha kwambiri, komanso zida zamakemikolo.

Kuphatikiza apo, silicon carbide yobwezeretsedwanso imakhala ndi kutentha kwambiri ndipo imatha kuyendetsa bwino kutentha, zomwe zimapangitsa kuti ikhale ndi phindu lofunika kwambiri muMa reactor a MOCVDndi zida zochizira kutentha popanga ma semiconductor wafer. Mphamvu yake yotenthetsera kutentha kwambiri komanso kukana kutentha kwambiri kumatsimikizira kuti zidazi zimagwira ntchito bwino kwambiri pakakhala zovuta kwambiri.

3. Kugwiritsa ntchito minda ya zoumba za silicon carbide zobwezerezedwanso

Kupanga ma semiconductor: Mu makampani opanga ma semiconductor, ma ceramic a silicon carbide obwezerezedwanso amagwiritsidwa ntchito popanga zinthu zoyambira ndi zothandizira mu ma MOCVD reactors. Chifukwa cha kukana kutentha kwambiri, kukana dzimbiri, komanso kutentha kwambiri, zinthu za RSiC zimatha kukhalabe ndi magwiridwe antchito okhazikika m'malo ovuta a chemical reaction, ndikuwonetsetsa kuti ma wafer a semiconductor ali ndi mtundu wabwino komanso wopindulitsa.

Makampani opanga ma photovoltaic: Mu makampani opanga ma photovoltaic, RSiC imagwiritsidwa ntchito popanga kapangidwe kothandizira zida zokulira ma kristalo. Popeza kukula kwa ma kristalo kuyenera kuchitika kutentha kwambiri panthawi yopanga ma cell a photovoltaic, kukana kutentha kwa silicon carbide yobwezeretsedwanso kumatsimikizira kuti zidazo zikugwira ntchito bwino kwa nthawi yayitali.

Zitofu zotentha kwambiri: Zipangizo za RSiC zimagwiritsidwanso ntchito kwambiri m'zitofu zotentha kwambiri, monga zophimba ndi zigawo za zitofu zotsukira mpweya, zitofu zosungunula ndi zida zina. Kukana kwake kutentha ndi kukana okosijeni kumapangitsa kuti ikhale imodzi mwa zipangizo zosasinthika m'mafakitale otentha kwambiri.

4. Kafufuzidwe ka njira zogwiritsira ntchito zoumba za silicon carbide zobwezerezedwanso

Chifukwa cha kufunikira kwakukulu kwa zipangizo zogwirira ntchito bwino, njira yofufuzira ya zoumba za silicon carbide zobwezerezedwanso yakhala ikuonekera pang'onopang'ono. Kafukufuku wamtsogolo adzayang'ana kwambiri mbali zotsatirazi:

Kukonza kuyera kwa zinthu: Pofuna kukwaniritsa zofunikira kwambiri pa kuyera m'magawo a semiconductor ndi photovoltaic, ofufuza akufufuza njira zowongolera kuyera kwa RSiC mwa kukonza ukadaulo woyika nthunzi kapena kuyambitsa zipangizo zatsopano zopangira, motero kuwonjezera phindu lake pakugwiritsa ntchito m'magawo apamwamba awa.

Kukonza kapangidwe kake kakang'ono: Mwa kuwongolera momwe zinthu zimakhalira zotentha komanso kufalikira kwa tinthu ta ufa, kapangidwe kake kakang'ono ka silicon carbide yobwezeretsedwanso kakhoza kukonzedwanso, motero kumawonjezera mphamvu zake zamakaniko komanso kukana kutentha.

Zipangizo zogwirira ntchito: Pofuna kuzolowera malo ovuta kugwiritsa ntchito, ofufuza akuyesera kuphatikiza RSiC ndi zipangizo zina kuti apange zipangizo zogwirira ntchito zomwe zili ndi zinthu zambiri, monga zipangizo zogwirira ntchito zopangidwa ndi silicon carbide zomwe zimakhala ndi mphamvu yolimba komanso mphamvu zamagetsi.

5. Mapeto

Monga chinthu chogwira ntchito bwino kwambiri, zoumba za silicon carbide zobwezerezedwanso zakhala zikugwiritsidwa ntchito kwambiri m'magawo ambiri chifukwa cha makhalidwe awo abwino kwambiri pakutentha kwambiri, kukana okosijeni komanso kukana dzimbiri. Kafukufuku wamtsogolo adzayang'ana kwambiri pakukonza kuyera kwa zinthu, kukonza kapangidwe kake kakang'ono komanso kupanga zida zogwirira ntchito zosiyanasiyana kuti zikwaniritse zosowa za mafakitale zomwe zikukula. Kudzera muukadaulo uwu, zoumba za silicon carbide zobwezerezedwanso zikuyembekezeka kukhala ndi gawo lalikulu m'magawo apamwamba kwambiri.
