Silicon Carbide Crucible: Xalka dhoobada Heerkulka Sare ee ugu dambeeya

1. Hordhac

Marka ay timaaddo maaraynta biraha dhalaalay, falcelinta heerkulka sare, ama xitaa dubista weelka aad jeceshahay, hal shay ayaa si joogto ah kor ugu kacaya loolanka: silicon karbohidrat crucible. Waxaa loo yaqaanaa kulaylkeeda gaarka ah, xoogga farsamada, iyo iska caabbinta shoogga kulaylka, Silicon carbide (SiC) waxay noqotay lama huraan dhammaan warshadaha - laga bilaabo aasaaska ilaa cunno wanaagsan. Laakiin maxaa ka dhigaya dhoobadan mid gaar ah? Sideese loo barbar dhigaa beddelka kale sida boron carbide ama silicon nitride? Aan quusno.

2. Waa maxay Silikon Kaarbide Crucible?

Qalabka silikoon carbide crucible waa weel laga sameeyay dhoobada silikoon carbide, oo loo farsameeyay in ay u adkeyso heerkulka aad u daran-badanaa ka badan 1,600°C (2,912°F). Si ka duwan dhoobo dhaqameed ama graphite saliib, Crucibles SiC waxay bixiyaan adkeysi sare, ballaarinta kulaylka ugu yar, iyo iska caabin heer sare ah ee daxalka kiimikada. Guryahani waxay ka dhigaan kuwo ku habboon dhalaalidda biraha aan birta ahayn sida aluminium, copper, iyo zinc, iyo sidoo kale shaybaarka iyo hababka kulaylka sare ee warshadaha.

3. Astaamaha Muhiimka ah ee Silicon Carbide

Kaaraynta Kalluunka ayaa u taagan iyadoo ay ugu wacan tahay isku dhafka gaarka ah ee sifooyinka:

• Adag aan caadi ahayn (labaad kaliya ilaa dheeman)
• Dhaqdhaqaaqa kulaylka sare (ka fiican inta badan biraha)
• Balaadhinta kulaylka hooseeya (waxay u adkaysataa dildilaaca isbeddelada heerkulka degdega ah)
• Kiimiko la'aan (waxay iska caabisaa oksaydhka iyo daxalka)
• Iska caabin xidhid heer sare ah

Tilmaamahani maaha oo kaliya inay ka dhigaan carbide silikon ku habboon saliib laakiin sidoo kale noocyo kala duwan oo codsiyo kale ah - laga bilaabo qaybaha warshadaha ilaa alaabta jikada ee maalinlaha ah.

4. Codsiyada Wershadaha iyo Farsamada ee Ka Dhan Crucibles

Halka carbide silicon waa la burburin karaa waa xiddig ku jira birta, kala duwanaanshiyaha SiC ayaa aad uga fog. Waxaa caadi ahaan loo adeegsadaa:

4.1. Qaybaha Heerkulka Sare

Tuubooyinka dhoobada Silicon carbide, oo ay ku jiraan silikoon carbide thermocouple tuubooyinka ilaalinta iyo tuubooyinka dhoobada silikoon carbide ee isticmaalka foornada, ayaa muhiim u ah deegaanka kulaylka sareeyo. Sidoo kale, tiirarka dhoobada ee silikoon carbide iyo leben carbide silikoon ayaa bixiya hufnaanta qaab dhismeedka kilns iyo reactors.

4.2. Tuubooyinka iyo Valves

Tuubooyinka dhoobada dhoobada ee Silicon carbide, silikoon carbide ceramic disk ee tuubada, iyo silikoon carbide dhoobada rubuc taabadaha leexashada qasabadaha SiC's xirashada iska caabinta iyo hawlgalka siman ee nidaamka xakamaynta biyaha. Xataa qanjidhada dhoobada dhoobada ee silicon carbide waxay ka faa'iidaystaan ​​cimrigooda.

4.3. Qalabka wax lagu shiido iyo goynta

Silicon carbide discs, saxannada dhoobada dhoobada ee silicon carbide, iyo silikoon carbide dheeman shiida saxanka dherya-samaynta ayaa si weyn loogu isticmaalaa mashiinada iyo dhamaystirka sababtoo ah dabeecadda xoqan ee SiC.

5. Silicon Carbide vs. Ceramics kale oo horumarsan

5.1. Boron Carbide vs Silicon Carbide

In kasta oo labaduba ay yihiin dhoobada aadka u adag, boron carbide waa ka fudud oo adag yahay-laakiin sidoo kale waa ka qaalisan yahay oo jajaban yahay. Silicon carbide waxa ay bixisaa iska caabin shoog kulaylka ka wanaagsan oo aad uga qiimo badan codsiyada baaxadda leh sida weelka iyo dahaarka foornada.

5.2. Isbarbardhigga Silikon Nitride

Silicon nitride ceramic waa walxo kale oo wax qabad sare leh, oo lagu qiimeeyay adkaanta jabkeeda iyo caabbinta shoogga kulaylka. Si kastaba ha ahaatee, wax soo saarka silicon nitride crucible warshadda ayaa caadi ahaan ka sii badan oo qaali ah. Qaybaha sida gaashaanka kulaylka silikoon nitride caado ah, giraanta nitride silikoon, iyo saxanka silikoon nitride waxay u adeegaan hawada sare ama doorarka semiconductor, halka silikoon carbide ay weli tahay ta loogu talagalay isticmaalka balaadhan ee warshadaha.

6. Kor u kaca Silicon Carbide ee dhoobada macaamiisha

Waxa la yaab leh, silikoon carbide ma aha oo kaliya warshado-waxa ay soo gelaysaa jikada. Thanks to haynta kulaylkeeda iyo dusha aan falcelin lahayn, soosaarayaashu hadda waxay soo saaraan:

• saxanka dubista dhoobada ee silicon carbide iyo saxanka dhoobada dubista silikoon
• Taarikada cashada ee silikoon carbide ceramik iyo saxannada dhoobada silikoon carbide ee cashada
• Silicon carbide dhoobada weelka lagu adeego, saxanka weelka dhoobada ee silicon carbide oo dabool leh,
• taarikada carruurta silikoon carbide dhoobada iyo taarikada dhoobada gacanta lagu sameeyo

Xitaa walxaha fasaxa ku jira sida silikoon carbide plates ceramik iyo silikoon carbide platter ceramic ayaa helaya caan. Noocyada sida Staub ayaa dhiirigeliyay nashqado ay ka mid yihiin saxanka dubista silikoon carbide, isku darka waxqabadka iyo qurxinta.

7. Foomamka Gaarka ah iyo xalalka gaarka ah

Marka laga reebo qaababka caadiga ah, silikoon carbide waxaa loo sameeyay qaabab aad u gaar ah:

• giraanta silikoon carbide iyo saxanadaha silikoon carbide ee daboolida ama dareenka
• Silicon carbide ceramic disk magnet iyo silikoon carbide piezo disc ceramik ee codsiyada elektarooniga ah
• tuubooyinka dhoobada silikoon carbide iyo tuubada dhoobada silikoon carbide ee loogu talagalay maaraynta dareeraha wasakhaysan
• rbsic silikoon carbide tile block iyo silikoon carbide dhoobada dhoobada ee dahaarka u adkaysta

Kuwani waxay muujinayaan la qabsiga SiC ee qaybaha oo dhan-laga bilaabo tamarta ilaa elektarooniga.

8. Gunaanad

Qalabka silikon carbide crucible waa wax ka badan dheriga dhalaalida - waa calaamad muujinaysa sida buundada dhoobada ah ee horumarsan ee buundada adag ee warshadaha iyo tamarta maalinlaha ah. Haddi aad birta ku shubayso goob qadiimiga ah, ku rakibayso waalka tuubada waara, ama aad casho ku bixinayso alaabta ceramik ee silikoon carbide, alaabtani waxa ay keenaysaa wax qabad aan la qiyaasi karin. Maaddaama farsamooyinka wax-soo-saarka ay wanaajiyaan oo ay baahidu u korto alaabada saafiga ah sida kuwa suuqa budada nitride silikoon nadiif ah, silikoon carbide wuxuu sii wadi doonaa inuu kobciyo - taas oo caddaynaysa in marmarka qaarkood, dhoobada ugu adag ay sidoo kale leedahay gaadhista ugu ballaaran.

Mareegahayaga oo la aasaasay Oktoobar 17, 2012, waa shirkad tignoolajiyadeed sare leh oo ay ka go'an tahay cilmi-baarista iyo horumarinta, wax soo saarka, farsamaynta, iibinta iyo adeegyada farsamada ee alaabta qaraabada dhoobada ah sida Silicon. Alaabadayada waxaa ku jira laakiin aan ku xaddidnayn Alaabooyinka dhoobada ah ee Boron Carbide, Alaabta dhoobada ee Boron Nitride, Alaabta dhoobada ee Silicon Nitride, Alaabta dhoobada ee Silicon Nitride, Alaabta dhoobada ee Zirconium Dioxide, iwm.
