Silicon Carbide Crucibles vs. Silicon Nitride: Murugo Qoto dheer ee Waxqabadka dhoobada Heerkulka Sare

1. Hordhac

Horumar weyn oo laga soo sheegay shalay, baahida caalamiga ah ee nadiifnimada sare silsiladda carbide Qaybaha kor u kaca 18% ee Q2 2024, oo ay dhaqaajisay kobaca wax soo saarka semiconductor iyo qaybaha tamarta dib loo cusboonaysiin karo (Isha: Warshadaha Ceramic Weekly). Kordhintaani waxay dib u soo celisay xiisaha loo qabo silikoon carbide crucibles- weelasha muhiimka ah ee birta dhalaalaysa iyo kiristaalo sii kordhaya - waxayna kicisay isbarbardhigga beddelka soo baxaya sida ceramics silicon nitride. Marka ay warshaduhu riixaan xadka heerkulka, iska caabinta daxalka, iyo xoogga farsamada, doorashada walxaha dhoobada saxda ah ayaa aad uga muhimsan waligeed.

2. Crucibles Silicon Carbide: Faraska Warshadaha

2.1. Maxaa Ka dhigay Crucibles Silicon Carbide Mid Gaar ah?

Kaaraynta Kalluunka crucibles ayaa lagu qiimeeyaa hab-dhaqankooda kulaylka ee gaarka ah, adkaantooda sare, iyo caabbinta shoogga kulaylka. Ka samaysan silikoon carbide oo isku xidhan ama falcelin ku xidhan (badanaa lagu calaamadiyaa RBSC ama RBSiC), weelashani waxay u adkeysan karaan heerkul ka badan 1,600°C. Qaab dhismeedkooda adag ayaa ka dhigaya kuwo ku habboon inay dhalaaliyaan biraha aan birta ahayn sida aluminium, copper, iyo zinc, iyo sidoo kale koritaanka shaybaarka.

2.2. Kala duwanaanshaha Guud iyo Foomamka Warshadaha

Ka sakow saqafyada, silsiladda carbide u muuqda qaabab badan oo la farsameeyay:

• leben carbide silikoon loogu talagalay dahaarka foornada
• tiirarka dhoobada silicon carbide iyo siddo silikoon taageero qaabdhismeed
• silikoon carbide gubida nozzles ee gubashada waxtarka sare leh
• Tuubooyinka carbide ee silikon (oo ay ku jiraan tuubooyinka ilaalinta kulaylaha iyo tuubooyinka dhoobada ah) ee deegaan aad u daran
• RBSiC silikoon carbide tile blocks oo loo isticmaalo sagxadaha adkaysiga u leh

Qaybahani waxay wadaagaan faa'iidooyinka asaasiga ah silicon carbide: caabbinta oksaydhka, balaadhinta kulaylka hooseeya, iyo waxqabadka xidhashada wanaagsan.

3. Silicon Nitride: Loolanka Waxqabadka Sare

3.1. Guryaha Agabka iyo Wax-soo-saarka

Silicon nitride (Si3N4) waa dhoobo kale oo horumarsan oo caan ku ah jabka adag ee adag iyo caabbinta shoogga kulaylka-badanaa ka sarreeya silikoon carbide codsiyada ku lug leh baaskiil wadida heerkulka degdega ah. Waxaa lagu soo saaray cadaadis aan cadaadis lahayn ama cadaadis isostatic oo kulul (HIP), budada silikoon nitride nadiif ah oo sarreeya ayaa lagama maarmaan u ah abuurista qaybo sida silicon nitride saliib, faraanti, taarikada, iyo gaashaammada kulaylka ee caadada u ah.

3.2. Codsiyada Degaanada Dalbashada

In kasta oo ka shaqayn yar marka loo eego silikoon carbide, silikoon nitride ayaa ka sarraysa halka isku halaynta farsamada ee walaaca ay muhiim tahay. Tusaalooyinka waxaa ka mid ah:

• caadadii silikoon nitride gaashaamo kulaylka hawada hawada
• silikoon nitride dhoobada dhoobada iyo shaabadihii
• Silicon nitride crucible warshad wax soo saarka ee metallurgy gaar ah

Kuleylkeeda hoose waxay dhab ahaantii noqon kartaa faa'iido doorarka diiradda saaraya daaha, in kasta oo ay caadi ahaan ku timaado kharash sare.

4. Madax-ilaa-Madax: Silicon Carbide vs. Silicon Nitride

4.1. Isbarbardhigga Kulul iyo Farsamo

Silicon carbide waxay ku faantaa tayada kulaylka sare (~ 120 W / m · K vs. ~ 30 W / m · K silikoon nitride), taas oo ka dhigaysa mid u fiican codsiyada u baahan wareejinta kulaylka degdega ah-sida qashinka ee aasaaska. Si kastaba ha ahaatee, silikoon nitride waxay leedahay jabka adag (6-8 MPa·m¹/² vs. 3-4 ee SiC), taasoo yaraynaysa khatarta masiibada ah ee fashilka masiibada ah ee culeyska farsamada ama baaskiil wadida kulaylka.

4.2. Qiimaha iyo Helitaanka

Silikoon carbide aad ayuu u badan yahay oo si fudud ayaa looga baaraandegi karaa cabir ahaan, taasoo horseedaysa kharash yar oo alaab ah sida silikoon carbide dhoobada dhoobada ama tuubbooyinka warshadaha. Silikon nitride ayaa weli ah walxo qaali ah, oo inta badan loo qoondeeyay codsiyada muhiimka ah halka guul-darradu aanay ahayn ikhtiyaar.

5. Warshadaha ka dambeeya: Kor u kaca Silicon Carbide ee dhoobada macaamiisha

Waxa xiiso leh, in sumcadda silikoon carbide ay ku daatay suuqyada macaamiisha. Iyadoo aan loo isticmaalin alaabta miis-dhaqameedka sababtoo ah midabkeeda mugdiga ah iyo qaabka warshadaha, qaar ka mid ah noocyada qaaliga ah waxay suuq geeyaan 'suxuunta dubista dhoobada silikon carbide' - in kasta oo kuwani ay yihiin kuwo si khaldan loo calaamadiyay ama glazes ka kooban raadadka SiC ee kor u qaadida kulaylka. Qalabka cashada ee silikoon carbide dhoobada dhabta ah (tusaale, silikoon carbide saxannada dhoobada cashada, saxannada dhoobada madow, ama suxuunta qasacadaysan ee foornada) waa naadir oo sida caadiga ah waxaa loo farsameeyay cunto kariye ama farshaxan.

Alaabooyinka sida silikoon carbide saxan subagga dhoobada leh oo dabool leh, suxuunta pie, saxannada saladh, iyo xitaa saxanadaha carruurta ayaa ka soo baxaya suuqyada khaaska ah, oo inta badan xoogga saaraya adkeysiga iyo shaqeynta foornada-miiska. Si kastaba ha ahaatee, macaamiishu waa inay xaqiijiyaan sheegashada alaabta-waxyaabo badan oo 'silicon carbide' ah oo ku jira jikada ayaa dhab ahaantii ah alaab-dhagax leh oo leh summadaha SiC-u waxyoonay (tusaale, 'suunka dubista silikon carbide Staub' waa eray raadin caadi ah, in kasta oo Staub uu isticmaalo birta dhalaalaysa ee aan SiC ahayn).

6. Foomamka Kale ee Silicon Carbide: Saxanadaha, Tubooyinka, iyo in ka badan

Kala duwanaanta Silicon carbide waxay ku fidsan tahay qaybaha saxda ah:

• saxanadaha carbide ee silicon iyo saxannada wax lagu shiidi karo ee goynta iyo turxaan bixinta
• qasabadaha saxanka dhoobada ee silicon carbide iyo valves-ka wareega rubuc ee tubooyinka
• tuubooyinka dhoobada silicon carbide iyo tuubooyinka loogu talagalay maaraynta dareeraha wasakhaysan
• Silicon carbide zirconia tuubooyinka loogu talagalay codsiyada kulaylka sarreeya

Kuwani waxay ka faa'idaystaan ​​adkaanta SiC iyo firfircoonaanta kiimikada, in kasta oo ay u baahan yihiin injineernimo taxaddar leh si loo maareeyo jajabnaanta.

7. Gunaanad

Iyadoo silikoon carbide crucibles ay weli tahay heerka dahabka ee hababka heerkulka sare ee warshadaha, silikoon nitride waxay bixisaa faa'iidooyin soo jiidasho leh marka loo eego xaaladaha dalbanaya adkeysiga ka sarreeya dhaqdhaqaaqa. Doorashada u dhaxaysaa waxay ku xidhan tahay baahiyo hawleed oo gaar ah, miisaaniyad, iyo filashooyinka meertada nolosha. Dhanka kale, xiisaha macaamilka ee 'suxuunta dhoobada silikon carbide' waxay ka tarjumaysaa isbeddel ballaaran oo agab warshadeed oo saameeya wax soo saarka qaab nololeedka-in kasta oo iibsadayaashu ay la xiriiraan sheegashooyinka suuqgeynta iyagoo leh shaki caafimaad qaba. Maaddaama suuqa budada nitride-ka silikoon ee nadiifka sare ah uu sii fidayo iyo miisaanka wax soo saarka silikoon carbide, labada dhoobada ayaa sii wadi doona qaabaynta mustaqbalka injineernimada deegaanka aadka u daran.
