Muuqaalka weligood isbeddelaya ee alaabada casriga ah, aluminium nitride porcelains (AlN) waxay runtii noqdeen beddelka ciyaarta suuqyada dalbanaya xalalka maaraynta kulaylka ee aan isbarbardhigga lahayn. Laga soo bilaabo qalabka elektiroonigga ah ee casriga ah ilaa injineernimada hawada sare, baahida agabka si guul leh u baabi'in kara kulaylka iyada oo la ilaalinayo sharafta qaabdhismeedka ayaa sii kordheysa. Ka mid ah caqabadaha, nitride aluminium khafiif ah ayaa u taagan kaliya ma aha kuleylkeeda heersare ah, laakiin sidoo kale sifooyinkeeda shaqo ee la taaban karo iyo sii jirista deegaanka. Qoritaankani waxa uu eegayaa cilmi-baadhista sayniska ee ka dambeysa AlN porcelains, sifooyinkooda asaasiga ah, iyo sababta ay u noqonayaan heerka dahabka ee codsiyada kulaylka ee waxqabadka sarreeya.
1. Waa maxay Miisaanka Aluminium Nitride Ceramics?
Aluminium nitride ceramics waa koorsada alaabada dhoobada casriga ah ee laga soo saaray aluminium fudud iyo atamka nitrogen. Qaab dhismeed ahaan, waxay ka yimaadaan nidaamka crystal-ka ee laba geesoodka ah waxayna soo bandhigaan hanti isku-dhafan oo ballaadhan, taasoo ka dhigaysa inay ku habboon yihiin codsiyada dhijitaalka ah iyo kuwa kulaylka labadaba. Si ka duwan sida shaagadaha caadiga ah sida alumina (Al ₂ O ₃), kuwaas oo ay xaddidan yihiin dhaqdhaqaaqa kulaylka oo la dhimay, AlN porcelains waxay buunbuuniyaan farqiga u dhexeeya kirishtaannada birta iyo kuwa dahaadhka ah. Isku dhafka khaaska ah ee kulaylka sare, hoos u dhigista dielectric joogto ah, iyo la'aanta kiimikaad ayaa iyaga u dhigaya wax soo saar kacaan ah caqabadaha tignoolajiyada casriga ah.
Wax soo saarka AlN porcelains waxaa ka mid ah farsamooyinka qallafsan sida plasma sintering (SPS) ama sintering aan cadaadis lahayn, sida caadiga ah lagu daro sida Y ₂ O ₃ ama CaF ₂ si kor loogu qaado dhumucda iyo yaraynta arrimaha. Nidaamyadani waxay xaqiijinayaan in badeecada ugu dambeysa ay ku guulaysato nadiifnimada sare (sida caadiga ah> 99.9%) iyo qaab-dhismeed yar oo joogto ah, oo muhiim u ah waxqabadka joogtada ah ee goobaha caanka ah.

5. Waa maxay sababta Miisaanka Aluminium Nitride uu u yahay Walxaha La Doorbiday ee Sheeramka Tamarta Kulaylka Sare?
Jawaabtu waxay ku xidhan tahay isku darka dhismayaasha aan la isku halayn ee AlN iyo la qabsiga mustaqbalka diyaarka u ah. Si ka duwan biraha, kuwaas oo sameeya diirimaad laakiin aan lahayn dahaarka korantada, ama porcelains caadiga ah, kuwaas oo ah dahaarka weli kuleylkoodu hooseeyo, AlN waxay ku dhufatay dheelitirka saxda ah. Halkan waa sababta ay u tahay doorashada la door biday:
Ka qaybgalka Dhibcaha Raaxo-darrada Aasaasiga ah: Qalabka elektiroonigga ah ee korontada ku shaqeeya, halkaasoo qaybo ka mid ah ay abuuraan kuleyl aad u weyn, kulaylka sare ee AlN wuxuu joojiyaa cararka kulaylka, sababta ugu weyn ee qalabka fashilantay. Tusaale ahaan, qaybaha korontada ku salaysan ee SiC oo ay weheliyaan substrate-yada AlN waxay ku gaadhaan 10x waxtarka weyn ee rogayaasha baabuurta korantada.
Future Tignoolajiyada Cadaynta: Sida suuqyadu u beddelaan 5G, AI, iyo IoT, baahida loo qabo wareegyada cufnaanta sare ee la yareeyey ayaa sii xoogaysanaysa. Waayida tamarta yar ee AlN iyo iswaafajinta kulaylka kuleylku waxay hubisaa in nidaamyadani ay yihiin kuwo lagu kalsoonaan karo marka ay jiraan xaalado daran.
Cidhifka Joogtada: Da'da diiradda saareysa tignoolajiyada casriga ah ee saaxiibtinimada leh, astaanta aan waxyeellada lahayn ee AlN iyo dib-u-warshadaynta waxay la jaanqaadaan yoolalka caalamiga ah ee eber-ka. Tani waxay u dhigaysaa ikhtiyaarka mas'uulka ah kuwa sameeya deegaanka miyir-qabka ah.
Faa'iidada Kharashka tartiib tartiib: Iyadoo AlN porcelains ay leeyihiin qiimo ka hor wakhtiga, cimrigooda dheer iyo dayactirka la yareeyay ayaa ka dhigaya kuwo wax ku ool ah mustaqbalka fog. Cilmi-baadhis ay samaysay Tokuyama Corp. waxay ogaatay in AlN substrates ee ku jira diode laser ay hoos u dhigeen wareegyada beddelka ah 60%, ilaalinta malaayiin kharashyada hawlgalka ah.
