Kodi chophimba cha silicon carbide ndi chiyani?

Chophimba cha silicon carbide,Chomwe chimadziwika kuti SiC covering, chimatanthauza njira yogwiritsira ntchito wosanjikiza wa silicon carbide pamalo pogwiritsa ntchito njira monga Chemical Vapor Deposition (CVD), Physical Vapor Deposition (PVD), kapena kupopera kutentha. Chophimba cha silicon carbide ichi chimawonjezera mphamvu za pamwamba pa zinthu zosiyanasiyana mwa kupereka kukana kwapadera kwa kuwonongeka, kukhazikika kwa kutentha, komanso chitetezo cha dzimbiri. SiC imadziwika ndi mphamvu zake zabwino kwambiri zakuthupi ndi zamakemikolo, kuphatikizapo malo osungunuka kwambiri (pafupifupi 2700℃), kuuma kwambiri (Mohs scale 9), kukana kwabwino kwambiri kwa dzimbiri ndi okosijeni, komanso magwiridwe antchito abwino kwambiri.

Ubwino Waukulu wa Silicon Carbide Coating mu Mafakitale Ogwiritsa Ntchito

Chifukwa cha zinthu zimenezi, chophimba cha silicon carbide chimagwiritsidwa ntchito kwambiri m'magawo monga ndege, zida zankhondo, ndi kukonza zinthu za semiconductor. M'malo ovuta kwambiri, makamaka mkati mwa 1800-2000℃, chophimba cha SiC chimawonetsa kukhazikika kwa kutentha komanso kukana kutentha, zomwe zimapangitsa kuti chikhale choyenera kugwiritsidwa ntchito kutentha kwambiri. Komabe, silicon carbide yokha ilibe umphumphu wofunikira pazinthu zambiri, kotero njira zophikira zimagwiritsidwa ntchito kuti zigwiritse ntchito mawonekedwe ake apadera popanda kuwononga mphamvu ya zigawo. Pakupanga zinthu za semiconductor, zinthu zopangidwa ndi silicon carbide zimapereka chitetezo chodalirika komanso kukhazikika kwa magwiridwe antchito mkati mwa zida zomwe zimagwiritsidwa ntchito mu MOCVD.

Njira Zodziwika Zokonzekera Kuphimba kwa Silicon Carbide

Ⅰ● Kuphimba kwa Nthunzi ya Mankhwala (CVD) Silicon Carbide

Mu njira iyi, zophimba za SiC zimapangidwa poika zinthu mu chipinda chochitira zinthu, komwe methyltrichlorosilane (MTS) imagwira ntchito ngati choyambira. Pansi pa mikhalidwe yolamulidwa—nthawi zambiri 950-1300°C ndi kupanikizika koipa—MTS imawonongeka, ndipo silicon carbide imayikidwa pamwamba. Njira yophimba iyi ya CVD SiC imatsimikizira kuti zophimbazo zimakhala zokhuthala, zofanana komanso zogwira ntchito bwino, zoyenera kugwiritsidwa ntchito molondola kwambiri m'magawo a semiconductor ndi aerospace.

Ⅱ● Njira Yosinthira Zinthu Zoyambirira (Kuyika Polymer ndi Pyrolysis - PIP)

Njira ina yothandiza yophikira silicon carbide ndi njira yosinthira precursor, yomwe imaphatikizapo kumiza chitsanzo chomwe chakonzedwa kale mu ceramic precursor solution. Pambuyo pochotsa utsi mu thanki yothira ndikuyika chivundikirocho pakanikiza, chitsanzocho chimatenthedwa, zomwe zimapangitsa kuti silicon carbide ipangidwe ikazizira. Njirayi ndi yabwino kwambiri pazinthu zomwe zimafuna makulidwe ofanana a silicon carbide komanso kukana kutopa kwambiri.

Katundu Wathupi wa Silicon Carbide Coating

Zophimba za silicon carbide zimakhala ndi makhalidwe abwino omwe amawapangitsa kukhala abwino kwambiri pantchito zamafakitale. Zinthu izi zikuphatikizapo:

Kutentha kwa Matenthedwe: 120-270 W/m·K
Kuchuluka kwa Kutentha: 4.3 × 10^^(-6)/K (pa 20~800℃)
Kukana kwa Magetsi: 10^⁵– 10^⁶Ω·cm
Kulimba: Mohs sikelo 9

Kugwiritsa Ntchito Silicon Carbide Coating

Pakupanga zinthu za semiconductor, silicon carbide yokutira ya MOCVD ndi njira zina zotenthetsera kwambiri imateteza zida zofunika kwambiri, monga ma reactor ndi ma susceptor, popereka kukana kutentha kwambiri komanso kukhazikika. Pakuyendetsa ndege ndi chitetezo, silicon carbide yokutira ya ceramic imagwiritsidwa ntchito pazinthu zomwe ziyenera kupirira kugundana mwachangu komanso malo owononga. Kuphatikiza apo, utoto wa silicon carbide kapena zokutira zingagwiritsidwenso ntchito pazida zamankhwala zomwe zimafuna kulimba pansi pa njira zoyeretsera.

Chifukwa Chiyani Muyenera Kusankha Silicon Carbide Coating?

Ndi mbiri yotsimikizika pakukulitsa moyo wa zigawo, zokutira za silicon carbide zimapereka kulimba kosayerekezeka komanso kukhazikika kwa kutentha, zomwe zimapangitsa kuti zikhale zotsika mtengo kuti zigwiritsidwe ntchito kwa nthawi yayitali. Posankha malo okhala ndi silicon carbide, mafakitale amapindula ndi kuchepa kwa ndalama zokonzera, kudalirika kwa zida, komanso magwiridwe antchito abwino.

N’chifukwa Chiyani Muyenera Kusankha Mphamvu ya Vet?

VET ENERGY ndi kampani yopanga zinthu zophimba silicon carbide ku China. Zinthu zazikulu zophimba SiC zimaphatikizapo chotenthetsera cha silicon carbide ceramic,CVD Silicon Carbide Coating MOCVD Susceptor, Chonyamulira cha MOCVD Graphite chokhala ndi CVD SiC Coating, Zonyamulira za SiC Zokutidwa ndi Graphite Base, Silicon Carbide Yokutidwa ndi Graphite Substrate ya Semiconductor,Chophimba cha SiC/Chophimba cha Graphite Substrate/Thireyi ya Semiconductor, CVD SiC Yokutidwa ndi Mpweya wa Carbon-carbon Composite CFC Boat MoldVET ENERGY yadzipereka kupereka njira zamakono komanso zothetsera mavuto kwa makampani opanga zinthu za semiconductor. Tikukhulupirira kuti tidzakhala mnzanu wa nthawi yayitali ku China.
