Main Application
1, iyo piezoelectric mudziyo application
Aluminium nitride ine high resistivity, high thermal conductivity (8-10 nguva yeAl2O3), uye yakaderera yekuwedzera coefficient yakafanana nesilicon, inova chinhu chakanaka chekushisa kwepamusoro uye magetsi emagetsi emagetsi.
2, iyo yemagetsi kurongedza substrate zvinhu
Iyo inowanzo shandiswa ceramic substrate zvinhu ndeye beryllium oxide, alumina, aluminium nitride, nezvimwewo, umo iyo alumina ceramic substrate ine yakaderera thermal conductivity, iyo thermal yekuwedzera coefficient haina kufanana nesilicon;kunyangwe beryllium oxide ine zvinhu zvakanakisa, asi hupfu hwayo hune muchetura zvakanyanya.
Pakati pezvinhu zviripo zveceramic zvinogona kushandiswa se substrate zvinhu, silicon nitride ceramic ine yakanyanya kubhenda simba, yakanaka kupfeka kuramba, ndeye ceramic material ine yakanakisa comprehensive mechanical performance, uye diki diki yekuwedzera yekuwedzera kwemafuta.Aluminium nitride ceramics ine yakakwira yekupisa conductivity, yakanaka yekupisa kukanganisa kuramba, uye ichine yakanaka michina zvivakwa pakupisa kwakanyanya.Panyaya yekushanda, aruminiyamu nitride uye silicon nitride pari zvino ndiyo yakanyatsokodzera zvinhu zvemagetsi packaging substrates, asi ivo vanewo dambudziko rakajairika nderekuti mutengo wakanyanya kukwirira.
3, uye inoshandiswa kune iyo luminescent zvinhu
Iyo yakakwira hupamhi hweyakananga bandgap gap yealuminium nitride (AlN) ndeye 6.2 eV, iyo ine yakakwirira photoelectric shanduko inoshanda kana ichienzaniswa neiyo indirect bandgap semiconductor.AlN Seyakakosha mwenje webhuruu uye UV mwenje-emitting zvinhu, inoiswa kune UV / yakadzika UV mwenje-emitting diode, UV laser diode uye UV detector.Uyezve, AlN inogona kuumba inoenderera yakasimba mhinduro neboka III nitrides senge GaN neInN, uye yayo ternary kana quaternary alloy inogona kuramba ichigadzirisa gaka rebhendi rayo kubva pakuonekwa kusvika kune yakadzika ultraviolet mabhendi, zvichiita kuti ive yakakosha yepamusoro-inoshanda luminescent zvinhu.
4, iyo inoshandiswa kune substrate zvinhu
Iwo makristasi eAlN inzvimbo yakakodzera yeGaN, AlGaN pamwe neAlN epitaxial zvinhu.Kuenzaniswa nesafire kana SiC substrate, AlN ine yakanyanya kupisa mechi neGaN, ine yakakwira makemikari kuenderana, uye kushoma kushushikana pakati pe substrate uye epitaxial layer.Naizvozvo, kana AlN crystal ichishandiswa seGaN epitaxial substrate, inogona kuderedza zvakanyanya density mumudziyo, kuvandudza mashandiro echishandiso, uye ine tarisiro yakanaka yekushandisa mukugadzirira kupisa kwepamusoro, frequency yakakwirira uye simba remagetsi. zvishandiso.
Pamusoro pezvo, iyo AlGaN epitaxial material substrate ine AlN crystal seyepamusoro aluminium (Al) chikamu chinogonawo kuderedza zvinobudirira density mu nitride epitaxial layer, uye inovandudza zvakanyanya kushanda uye hupenyu hwebasa renitride semiconductor device.Yepamusoro-mhando yemazuva ese-mapofu ma detectors akavakirwa paAlGaN akaiswa zvinobudirira.
5, inoshandiswa muceramics uye refractory zvinhu
Aluminium nitride inogona kuiswa kune sintering yezvigadzirwa zveceramics, yakagadzirwa aruminiyamu nitride ceramics, kwete chete yakanaka michina zvinhu, kupeta simba rakakwirira kupfuura Al2O3 uye BeO Ceramics, yakakwirira kuoma, asiwo yakakwirira tembiricha uye ngura kuramba.Uchishandisa AlN Ceramic heat resistance uye corrosion resistance, inogona kushandiswa kugadzira tembiricha isingadzivirirwe necorrosion senge crucible uye Al evaporation plate.Uye zvakare, yakachena AlN ceramics makristasi asina ruvara akajeka, ane akanakisa optical zvivakwa, uye anogona kushandiswa seyakanyanya tembiricha infrared hwindo uye kupisa inodzivirira coating yeyakajeka ceramics kugadzira emagetsi optical zvishandiso.
6. Macomposites
Epoxy resin / AlN inoumbwa zvinhu, sechinhu chekurongedza, inoda yakanaka yekupisa conductivity uye kugona kupisa kupisa, uye ichi chinodiwa chiri kuwedzera kuomarara.Sechinhu chepolymer chine zvakanaka chemakemikari zvimiro uye kugadzikana kwemuchina, epoxy resin iri nyore kurapa, ine yakaderera shrinkage rate, asi thermal conductivity haina kukwirira.Nekuwedzera AlN nanoparticles ine yakanakisa yekupisa conductivity kune epoxy resin, iyo yekupisa conductivity uye simba zvinogona kuvandudzwa zvinobudirira.
