(I-AlN ecinezelekileyoIveliswe nguWintrustek)

IAluminiyam nitride (AIN) idume ngokusebenza kwayo kakuhle kwe-thermal kunye neempawu ezikhethekileyo zokugquma umbane. Yinto eqhelekileyo yeceramic esetyenziswa kuluhlu olubanzi lwezixhobo zombane. Iiseramikhi ze-aluminiyam nitride ziyaxhathisa kwisinyithi esinyibilikisiweyo, kuquka ikopolo, i-lithium, kunye ne-aluminiyam, ngaphezu kokwandiswa kwe-thermal kunye neempawu zokukhusela umbane. I-Aluminiyam nitridesisixhobo esiluncedo kwiinkqubo ezahlukeneyo zemizi-mveliso ngenxa yeekhemikhali zayo kunye neempawu zayo.

Nangona kunjalo, ekuveliseni, i-aluminiyam nitride yahlulwe ngokukodwa kwiindidi ezimbini ngokusekwe kwinkqubo ye-sintering: pr.essureless sintered aluminiyam nitride kwayei-aluminiyam nitride ecinezelwe ngokushushu. Iimpawu kunye nokusetyenziswa kwezi ndidi zimbini zahluke kakhulu.

I-aluminiyam ye-nitride engenaxinzeleloixuba i-aluminium ephezulu ecocekileyo ye-nitride powder kunye nexabiso elincinci le-sintering aid (efana ne-Y2O3), ukubumba umxube kwifom efunwayo (umzekelo, ngokucinezela okomileyo okanye ukucinezela kwe-isostatic), kwaye emva koko ukucwiliswa kwiqondo lokushisa eliphezulu (1800 ° C ukuya kwi-2000 ° C) phantsi kwendawo ekhuselayo ye-inert (nitrogen). Le nkqubo ixhomekeke kwi-reaction phakathi kwe-sintering aid kunye ne-alumina ekhoyo kumphezulu we-AlN amasuntswana, okwenza isigaba solwelo esikhuthaza ukulungiswa kwakhona kunye nokuxinana kwamasuntswana.

Iimpawu:

• Iindleko eziphantsi: iimfuno zezixhobo zilula, okwenza ukuba zilungele ukuveliswa kobunzima obukhulu.

• Iimilo ezintsonkothileyo: inokuvelisa iindawo ezahlukeneyo ezinokwakheka ngokungalungelelananga kunye neepleyiti ezibhityileyo (ezifana neesubstrates zeceramic).

• Ukusebenza: nangona inokuthi ihlangabezane neemfuno ezininzi zoshishino, ngenxa yokungabikho koxinzelelo lwangaphandle, ama-pores amancinci akhoyo ngokulula kwizinto eziphathekayo, kwaye ubuninzi buhlala buphakathi kwe-97% kunye ne-99%.

Usetyenziso oluphambili:

• Ii-substrates zokupakisha ze-Semiconductor (ezifana ne-LED kunye ne-module substrates zamandla)

• Iisinki zobushushu kunye neegaskets ezikhuselayo

• Isixhobo esikwaziyo ukumelana nokutyiwa kunye nokumelana nobushushu

I-aluminiyam i-nitride ecinezelwe ngokushushuiveliswa kusetyenziswa inkqubo ekhethekileyo ebizwa ngokuba yi-hot pressing. Ngexesha lobushushu obuphezulu be-sintering, uxinzelelo oluphezulu lwe-unidirectional lwamashumi okanye namakhulu e-megapascals lusetyenziswa kwizinto eziphathekayo. Le mpembelelo ye-synergistic yokushisa okuphezulu kunye noxinzelelo oluphezulu lungundoqo ekufezekiseni ukusebenza kwayo okukhethekileyo.

Iimpawu:

• Uxinaniso oluphezulu kakhulu: uxinzelelo lunyanzelela ngaphandle iimbobo phakathi kwamasuntswana, okukhokelela kuxinaniso olunokusondela kwixabiso lethiyori (＞99%).

• Iipropathi ezigqwesileyo zoomatshini: xa kuthelekiswa ne-AlN ene-sintered eqhelekileyo, i-AlN ecinezelekileyo inamandla aphezulu okuguquguquka kunye nobunzima.

• I-conductivity egqwesileyo ye-thermal: ngenxa ye-porosity ephantsi kakhulu, ukuchithwa kwe-phonon kuyancipha, kwaye ukuqhutyelwa kwayo kwe-thermal ngokuqhelekileyo kuzinzile kwaye kusondele kumda ophezulu.

• Ukulinganiselwa: ixabiso eliphezulu, ukusebenza kakuhle kwemveliso, kwaye ngokuqhelekileyo iimilo zejometri ezilula ezifana neediski okanye iibhloko zinokusetyenzwa.

Usetyenziso oluphambili (iimfuno ezikhethekileyo ezikumgangatho ophezulu):

• Ukutshatyalaliswa kobushushu kunye nokupakishwa kweelaser zamandla aphezulu

• Isizukulwana esilandelayo soxinaniso lwamandla kanomathotholo/izixhobo zemicrowave

• Ukutshatyalaliswa kobushushu kwiinkqubo ze-elektroniki ezithembeke kakhulu kwibala le-aerospace

• Izixhobo zophando lwezenzululwazi okanye amacandelo ovavanyo lwebenchmark phantsi kweemeko ezithile ezigqithisileyo

Khethai-aluminiyam i-nitride engenaxinzeleloukuba: Usebenza ngeebhodi zesekethe zombane (PCBs), iisinki zobushushu be-LED, okanye izinto ezilula zokugquma kushishino. I-aluminiyamu ye-nitride engenaxinzelelo yeyona ndlela inendleko kakhulu kwaye ikhulile.

Khethai-aluminiyam nitride ecinezelwe ngokushushuukuba: Indawo yesicelo sakho inzima kakhulu, enje ngee-electrostatic chucks (ESCs) zezixhobo ze-semiconductor etching, iziseko zelaser ezisebenza kakhulu, okanye izinto ezichanekileyo ezifuna ukumelana noxinzelelo oluphezulu lomatshini. Ukuxinana kunye namandla aluncedo e-aluminiyam nitride ecinezelekileyo ayinakuphinda ithathelwe indawo kwezi meko.
