(I-AlN ecindezelwe okushisayoIkhiqizwe nguWintrustek)

I-Aluminium nitride (AIN) idume ngokuguquguquka kwayo okuhle kakhulu kwe-thermal kanye nezimfanelo ezihlukile zokuvikela ugesi. Kuyinto evamile ye-ceramic esetshenziswa ezinhlobonhlobo zemishini kagesi. Amaceramic e-aluminium nitride amelana nezinsimbi ezincibilikisiwe, okuhlanganisa ithusi, i-lithium, ne-aluminium, ngaphezu kokunwetshwa kwawo okushisayo nezici zokuvikela ugesi. I-Aluminium nitrideiwumsebenzi owusizo ezinhlelweni ezihlukahlukene zezimboni ngenxa yezakhi zayo zamakhemikhali nezomzimba.

Kodwa-ke, ekukhiqizeni, i-aluminiyamu nitride ihlukaniswa ngokuyinhloko ibe izinhlobo ezimbili ngokusekelwe kunqubo yokufaka: i-pr.essureless sintered aluminium nitride futhii-aluminium nitride ecindezelwe ngokushisayo. Izici nokusetshenziswa kwalezi zigaba ezimbili kwehluka kakhulu.

I-aluminium nitride engenasiciixuba i-high-purity aluminium nitride powder ngenani elincane le-sintering aid (efana ne-Y2O3), ibumba ingxube ibe yifomu elifunayo (isibonelo, ngokucindezela okomile noma ukucindezela kwe-isostatic), bese uyicwilisa ekushiseni okuphezulu (1800 ° C kuya ku-2000 ° C) ngaphansi kwesimo se-inert esivikelayo (i-nitrogen). Le nqubo incike ekuphenduleni phakathi kosizo lwe-sintering kanye ne-alumina ekhona ebusweni bezinhlayiya ze-AlN, kwakheka isigaba soketshezi esikhuthaza ukuhlelwa kabusha kanye nokuminyana kwezinhlayiya.

Izici:

• Izindleko eziphansi: izidingo zemishini zilula, okwenza ifanelekele ukukhiqizwa ngobuningi obukhulu.

• Izimo eziyinkimbinkimbi: ingakha izingxenye ezihlukahlukene ezimise ngendlela engavamile kanye namapuleti amancane (njengama-substrates e-ceramic).

• Ukusebenza: nakuba ingahlangabezana nezidingo eziningi zezimboni, ngenxa yokuntuleka kokucindezela kwangaphandle, ama-pores amancane atholakala kalula endabeni, futhi ukuminyana kuvame ukuba phakathi kuka-97% no-99%.

Izinhlelo zokusebenza eziyinhloko:

• Ama-substrates okupakisha we-semiconductor (njenge-LED namamojula angaphansi wemojula yamandla)

• Amasinki okushisa kanye nama-gaskets okuvikela

• Izingxenye zedivayisi ezimelana nokugqwala futhi zimelana nokushisa

I-aluminium nitride ecindezelwe ngokushisayokukhiqizwa kusetshenziswa inqubo ekhethekile ebizwa ngokuthi ukucindezela okushisayo. Ngesikhathi sokushisa okuphezulu kwe-sintering, i-unidirectional high pressure yamashumi noma ngisho namakhulu ama-megapascals isetshenziswa endabeni. Lo mphumela we-synergistic wokushisa okuphezulu nomfutho ophezulu uyisihluthulelo sokufeza ukusebenza kwawo okuyingqayizivele.

Izici:

• Ukuminyana okuphezulu kakhulu: ingcindezi iphoqa ukuphuma kwezimbotshana phakathi kwezinhlayiya, okuholela ekuminyaneni okungasondela kunani lethiyori (＞99%).

• Izakhiwo zemishini ezinhle kakhulu: uma kuqhathaniswa ne-AlN ecindezelwe ngokushisayo, i-AlN ecindezelwe ngokushisayo inamandla aphezulu okuguquguquka nobulukhuni.

• Ukuhamba kahle kwe-thermal: ngenxa ye-porosity ephansi kakhulu, ukuhlakazeka kwe-phonon kuyancipha, futhi ukuqhutshwa kwayo okushisayo kuvame ukuzinza futhi kusondele kumkhawulo ophezulu.

• Imikhawulo: izindleko eziphezulu, ukusebenza kahle kokukhiqiza okuphansi, futhi ngokuvamile kuphela izimo ezilula zejometri ezifana namadiski noma amabhulokhi angacutshungulwa.

Izinhlelo zokusebenza eziyinhloko (izidingo ezikhethekile ezisezingeni eliphezulu):

• Ukukhipha ukushisa nokupakishwa kwama-laser anamandla amakhulu

• Esizukulwaneni esilandelayo i-high-power density radio frequency/imishini ye-microwave

• Ukukhishwa kokushisa kwamasistimu kagesi athembeke kakhulu kumkhakha we-aerospace

• Impahla yocwaningo lwesayensi noma izingxenye zokuhlola ibhentshimakhi ngaphansi kwezimo ezithile ezimbi kakhulu

Kufanele ukhethe kanjani?

Khethai-aluminium nitride engenangcindeziuma: Usebenza ngamabhodi esekethe e-elekthronikhi (ama-PCB), osinki bokushisa be-LED, noma izingxenye ezilula zokufakwa kwezimboni. I-aluminum nitride engenangcindezi iyindlela engabizi kakhulu futhi evuthiwe.

Khethai-aluminium nitride ecindezelwe ngokushisayouma: Indawo yakho yohlelo lokusebenza idinga kakhulu, njengama-electrostatic chucks (ESCs) emishini yokufaka i-semiconductor, izisekelo ze-laser ezisebenza kahle, noma izingxenye zesakhiwo ezinembayo ezidinga ukumelana nokucindezeleka okuphezulu komshini. Ukuminyana namandla okuzuzisa kwe-aluminiyamu nitride ecindezelwe ngokushisayo akunakuthathelwa indawo kulezi zimo.
