Kodi zokutira za silicon carbide ndi chiyani?

Kupaka silicon carbide,Zomwe zimadziwika kuti SiC ❖ kuyanika, zimatanthawuza njira yogwiritsira ntchito silicon carbide pamtunda kudzera mu njira monga Chemical Vapor Deposition (CVD), Physical Vapor Deposition (PVD), kapena kupopera mbewu mankhwalawa ndi kutentha. Chophimba ichi cha silicon carbide ceramic chimakulitsa mawonekedwe a magawo osiyanasiyana popereka kukana kwapadera, kukhazikika kwamafuta, ndi chitetezo cha dzimbiri. SiC imadziwika ndi mawonekedwe ake owoneka bwino akuthupi ndi mankhwala, kuphatikiza malo osungunuka kwambiri (pafupifupi 2700 ℃), kulimba kwambiri (Mohs sikelo 9), kukana kwa dzimbiri ndi okosijeni, komanso magwiridwe antchito apadera.

Ubwino Waikulu Wa Kupaka Silicon Carbide mu Ntchito Zamakampani

Chifukwa cha izi, zokutira za silicon carbide zimagwiritsidwa ntchito kwambiri m'magawo monga zakuthambo, zida zankhondo, ndi kukonza kwa semiconductor. M'malo ovuta kwambiri, makamaka mkati mwa 1800-2000 ℃, zokutira za SiC zimawonetsa kukhazikika kwamafuta komanso kukana kwa ablative, zomwe zimapangitsa kuti zikhale zoyenera kugwiritsa ntchito kutentha kwambiri. Komabe, silicon carbide yokhayo ilibe umphumphu wofunikira pazinthu zambiri, kotero njira zokutira zimagwiritsidwa ntchito kuti ziwongolere mawonekedwe ake apadera popanda kusokoneza mphamvu zamagulu. Popanga semiconductor, zinthu zokutira za silicon carbide zimapereka chitetezo chodalirika komanso kukhazikika kwa magwiridwe antchito mkati mwa zida zomwe zimagwiritsidwa ntchito munjira za MOCVD.

Njira Zodziwika Zokonzekera Kupaka Silicon Carbide

Ⅰ● Chemical Vapor Deposition (CVD) Silicon Carbide Coating

Mwa njira iyi, zokutira za SiC zimapangidwa poyika magawo mu chipinda chochitiramo, pomwe methyltrichlorosilane (MTS) imakhala ngati kalambulabwalo. Pansi pazikhalidwe zolamulidwa - nthawi zambiri 950-1300 ° C ndi kupsinjika koyipa - MTS imawonongeka, ndipo silicon carbide imayikidwa pamwamba. Njira yokutira iyi ya CVD SiC imatsimikizira zokutira wandiweyani, zofananira zomatira bwino kwambiri, zokomera kugwiritsa ntchito mwatsatanetsatane m'magawo a semiconductor ndi zamlengalenga.

Ⅱ● Precursor Conversion Method (Polymer Impregnation ndi Pyrolysis - PIP)

Njira ina yogwiritsira ntchito silicon carbide kupopera kutsitsi ndi njira yosinthira kalambulabwalo, yomwe imaphatikizapo kumiza zitsanzo zomwe zidakonzedweratu mu yankho la ceramic precursor. Pambuyo popukuta thanki yoyikirapo ndikukakamiza zokutira, chitsanzocho chimatenthedwa, zomwe zimapangitsa kuti silicon carbide ipangidwe pozizira. Njirayi imayamikiridwa pazinthu zomwe zimafuna makulidwe a ❖ kuyanika yunifolomu komanso kulimbikira kukana kuvala.

Zakuthupi za Silicon Carbide Coating

Zovala za silicon carbide zimawonetsa zinthu zomwe zimawapangitsa kukhala abwino pantchito zamafakitale. Zinthu izi zikuphatikizapo:

Kuthamanga kwa Matenthedwe: 120-270 W/m·K
Coefficient of thermal Expansion: 4.3 × 10 ^^(-6)/K (pa 20 ~ 800 ℃)
Kukaniza kwamagetsi: 10 ^⁵-10^⁶Ω·cm
Kuuma: Mohs sikelo 9

Kugwiritsa ntchito Silicon Carbide Coating

Popanga semiconductor, zokutira za silicon carbide za MOCVD ndi njira zina zotentha kwambiri zimateteza zida zofunikira, monga ma reactors ndi susceptors, popereka zonse kukana kutentha kwambiri komanso kukhazikika. Muzamlengalenga ndi chitetezo, zokutira za silicon carbide ceramic zimagwiritsidwa ntchito pazinthu zomwe ziyenera kupirira kuthamanga kwambiri komanso malo owononga. Kuphatikiza apo, utoto wa silicon carbide kapena zokutira zitha kugwiritsidwanso ntchito pazida zamankhwala zomwe zimafunikira kulimba pochita zoletsa.

Chifukwa Chiyani Sankhani Silicon Carbide Coating?

Ndi mbiri yotsimikizika pakukulitsa moyo wamagulu, zokutira za silicon carbide zimapereka kukhazikika kosayerekezeka ndi kukhazikika kwa kutentha, kuzipangitsa kukhala zotsika mtengo kuti zigwiritsidwe ntchito nthawi yayitali. Posankha malo okhala ndi silicon carbide, mafakitale amapindula ndi kuchepa kwa mtengo wokonza, kudalirika kwa zida, komanso kuyendetsa bwino ntchito.

Chifukwa Chiyani Sankhani VET ENERGY?

VET ENERGY ndi katswiri wopanga ndi fakitale ya zinthu zokutira za silicon carbide ku China. Zopangira zazikulu zokutira za SiC zimaphatikizapo chotenthetsera cha silicon carbide ceramic choyatira,CVD Silicon Carbide Coating MOCVD Susceptor, MOCVD Graphite Carrier yokhala ndi CVD SiC Coating, SiC Coated Graphite Base Carriers, Silicon Carbide Coated Graphite Substrate ya Semiconductor,Kupaka kwa SiC / Coated Graphite Substrate/Treyi ya Semiconductor, CVD SiC Yokutidwa ndi Carbon-carbon Composite CFC Boat Mold. VET ENERGY yadzipereka kupereka ukadaulo wapamwamba kwambiri komanso mayankho azinthu pamakampani a semiconductor. Tikukhulupirira moona mtima kukhala bwenzi lanu kwa nthawi yaitali ku China.
