Aluminium nitride (AIN) imadziwikanso chifukwa cha kukhathamiritsa kwabwino kwa matenthedwe komanso zida zapadera zotsekera magetsi. Ndi chinthu chodziwika bwino cha ceramic chomwe chimagwiritsidwa ntchito pazida zosiyanasiyana zamagetsi. Zoumba za aluminiyamu za nitride zimagonjetsedwa ndi zitsulo zosungunuka, kuphatikizapo mkuwa, lithiamu, ndi aluminiyamu, kuwonjezera pa kukula kwake kwa kutentha ndi mphamvu zotsekereza magetsi. Aluminium nitridendi zothandiza pamafakitale osiyanasiyana chifukwa cha mankhwala ake komanso mawonekedwe ake.
Komabe, popanga, aluminiyamu nitride imagawidwa m'mitundu iwiri kutengera sintering: pr.essureless sintered aluminium nitride ndialuminium nitride yotenthedwa ndi kutentha. Mawonekedwe ndi machitidwe a magulu awiriwa amasiyana kwambiri.
Aluminiyamu nitride wopanda Pressureamasakaniza ufa wa aluminiyamu wa nitride wonyezimira ndi kagawo kakang'ono ka sintering (monga Y2O3), kupanga chisakanizocho kukhala mawonekedwe ofunikira (mwachitsanzo, mwa kukanikiza kowuma kapena kuponderezedwa kwa isostatic), ndiyeno kuzizira kutentha kwakukulu (1800 ° C mpaka 2000 ° C) pansi pa mlengalenga wotetezera (nitrogen). Izi zimadalira zomwe zimachitika pakati pa chithandizo cha sintering ndi aluminiyamu yomwe ilipo pamwamba pa AlN particles, kupanga gawo lamadzimadzi lomwe limalimbikitsa kukonzanso ndi kukhazikika kwa particles.
Mawonekedwe:
Mtengo wotsika: zofunikira za zida ndizosavuta, zomwe zimapangitsa kuti zikhale zoyenera kupanga zazikulu.
Maonekedwe ovuta: imatha kupanga magawo osiyanasiyana osawoneka bwino ndi mbale zoonda (monga ma ceramic substrates).
Magwiridwe: ngakhale amatha kukwaniritsa zosowa zambiri zamafakitale, chifukwa chosowa kukakamiza kwakunja, ma pores ang'onoang'ono amapezeka mosavuta pazinthuzo, ndipo kachulukidwe kake kamakhala pakati pa 97% ndi 99%.
Kugwiritsa Ntchito Kwambiri:
Ma semiconductor packaging substrates (monga ma LED ndi ma module amphamvu)
Kutentha kwamadzi ndi ma gaskets otetezera
Zida zomwe zimalimbana ndi dzimbiri komanso zosagwira kutentha
Aluminiyamu nitride yotenthedwa ndi kutenthaamapangidwa pogwiritsa ntchito njira yapadera yotchedwa hot pressing. Panthawi yotentha kwambiri, kupanikizika kwakukulu kwa unidirectional kwa makumi kapena mazana a megapascals kumagwiritsidwa ntchito pazinthuzo. Izi synergistic zotsatira za kutentha kwambiri ndi kuthamanga kwapamwamba ndizofunikira kwambiri kuti akwaniritse ntchito yake yapadera.
Mawonekedwe:
Kuchulukirachulukira kwambiri: kukakamiza kumatulutsa pores pakati pa tinthu tating'onoting'ono, zomwe zimapangitsa kuti pakhale kachulukidwe komwe kumatha kuyandikira mtengo wamalingaliro (＞99%).
Katundu wamakina abwino kwambiri: poyerekeza ndi AlN yomwe sintered, AlN yotenthetsera imakhala ndi mphamvu zosinthasintha komanso zolimba.
Kutentha kwabwino kwambiri: chifukwa cha kutsika kwambiri, kufalikira kwa phonon kumachepetsedwa, ndipo matenthedwe ake amatenthedwa nthawi zambiri amakhala okhazikika komanso oyandikira malire apamwamba.
Zolepheretsa: kukwera mtengo, kutsika kwapang'onopang'ono, ndipo mawonekedwe osavuta a geometric okha monga ma disks kapena midadada amatha kukonzedwa.
Ntchito zazikulu (zofunika zapamwamba kwambiri):
Kutaya kutentha ndi kulongedza kwa ma lasers amphamvu kwambiri
Zida za m'badwo wotsatira zamphamvu kwambiri za ma radio frequency/microwave
Kutentha kwamagetsi kwamagetsi odalirika kwambiri odalirika m'munda wazamlengalenga
Zida zofufuzira zasayansi kapena zida zoyezera benchmark pansi pazovuta zina
Kodi muyenera kusankha bwanji?
Sankhanialuminium nitride yopanda mphamvungati: Mukugwira ntchito ndi ma board amagetsi amagetsi (PCBs), masinki otentha a LED, kapena zida zosavuta zotchinjiriza mafakitale. Pressureless aluminium nitride ndiye njira yotsika mtengo komanso yokhwima.
Sankhanialuminium nitride yotenthedwa ndi kutenthangati: Malo anu ogwiritsira ntchito ndi ovuta kwambiri, monga ma electrostatic chucks (ESCs) a zida za semiconductor etching, ma laser ochita bwino kwambiri, kapena zigawo zolondola zomwe zimafunikira kupirira kupsinjika kwamakina. Kachulukidwe ndi mphamvu za ma aluminium nitride opanikizidwa ndi otentha sizingalowe m'malo mwazochitika izi.
