Aluminium Nitride Crucible ALN Aluminium Crucible
Tlhahiso ea Sehlahisoa
AlN E entsoe ka phokotso ea mocheso ea alumina kapa ka nitride e tobileng ea alumina.E na le boima ba 3.26 e Ngolisitsoeng le e Sirelelitsoeng ke MarkMonitor-3, leha e sa qhibilihe, e bola ka holimo ho 2500 ° C moeeng.Thepa e kopantsoe ka thata 'me e hanana le sintering ntle le thuso ea motsoako o etsang mokelikeli.Ka tloaelo, li-oxide tse kang Y 2 O 3 kapa CaO li lumella ho fihlela sintering ka mocheso o pakeng tsa 1600 le 1900 °C.
Aluminium nitride ke thepa ea ceramic e nang le ts'ebetso e phethahetseng e felletseng, 'me lipatlisiso tsa eona li ka saloa morao lilemong tse fetang lekholo tse fetileng.E entsoe ka F. Birgeler le A. Geuhter E Fumaneha ka 1862, 'me ka 1877 ke JW MalletS Aluminium nitride e ile ea etsoa ka lekhetlo la pele, empa e ne e se ts'ebeliso e sebetsang ka lilemo tse fetang 100, ha e ne e sebelisoa e le manyolo a lik'hemik'hale. .
Hobane nitride ea aluminium ke motsoako o kopaneng, o nang le coefficient e nyane ea ho itšehla thajana le sebaka se phahameng sa ho qhibiliha, ho thata ho sesa.E ne e se ho fihlela lilemong tsa bo-1950 moo lirafshoa tsa aluminium nitride li ileng tsa hlahisoa ka katleho ka lekhetlo la pele 'me tsa sebelisoa e le thepa e hanyetsang ho qhibiliha ha tšepe e hloekileng, aluminium le motsoako oa aluminium.Ho tloha lilemong tsa bo-1970, ka ho teba ha lipatlisiso, mokhoa oa ho lokisa aluminium nitride o ntse o hōla ka ho fetisisa, 'me boholo ba ts'ebeliso ea eona bo ntse bo eketseha.Haholo-holo ho tloha lekholong la bo21 la lilemo, ka tsoelo-pele e potlakileng ea thekenoloji ea microelectronics, mochine oa elektroniki le lisebelisoa tsa elektroniki tse lebisang ho miniaturization, bobebe, kopanyo, le ts'epo e phahameng le tataiso e phahameng ea tlhahiso ea matla, lisebelisoa tse rarahaneng le ho feta tsa substrate le thepa ea ho paka ea ho qhala mocheso. ho fetisa litlhoko tse phahameng, ho ntšetsa pele nts'etsopele e matla ea indasteri ea aluminium nitride.
Likarolo tse ka Sehloohong
AlN Hanela ho khoholeha ha litšepe tse ngata tse qhibilihisitsoeng, haholo-holo aluminium, lithium le koporo.
E hanana le khoholeho e ngata ea letsoai le qhibilihisitsoeng, ho kenyelletsa le chloride le cryolite
Ts'ebetso e phahameng ea mocheso oa thepa ea ceramic (kamora beryllium oxide)
Restivity e phahameng ea molumo
Matla a phahameng a dielectric

Ka mokhoa oa phofo, e bonolo ho hydrolyzed ka metsi kapa mongobo
Kopo e ka Sehloohong
1, sesebelisoa sa sesebelisoa sa piezoelectric
Aluminium nitride e na le resistivity e phahameng, conductivity e phahameng ea mocheso (linako tse 8-10 tsa Al2O3), le coefficient e tlaase ea ho atolosa e tšoanang le silicon, e leng thepa e loketseng bakeng sa mocheso o phahameng le lisebelisoa tsa elektronike tse matla.
2, thepa ea elektronike ambalaji substrate
Lisebelisoa tse sebelisoang ka tloaelo tsa ceramic substrate ke beryllium oxide, alumina, aluminium nitride, joalo-joalo, moo substrate ea alumina ceramic e nang le conductivity e tlaase ea mocheso, coefficient ea ho atolosa mocheso ha e lumellane le silicon;le hoja beryllium oxide e na le thepa e babatsehang, empa phofo ea eona e chefo haholo.
Har'a lisebelisoa tse teng tsa ceramic tse ka sebelisoang e le lisebelisoa tsa substrate, silicon nitride ceramic e na le matla a holimo ka ho fetisisa a ho kobeha, ho hanyetsa ho apara hantle, ke thepa ea ceramic e nang le ts'ebetso e ntle ka ho fetisisa ea mochine, le coefficient e nyenyane ka ho fetisisa ea ho atolosa mocheso.Li-ceramics tsa aluminium nitride li na le conductivity e phahameng ea mocheso, li hanyetsa mocheso o motle, 'me li ntse li na le thepa e ntle ea mochine mocheso o phahameng.Mabapi le ts'ebetso, aluminium nitride le silicon nitride hajoale ke lisebelisoa tse loketseng ka ho fetisisa bakeng sa li-substrates tsa elektronike, empa hape li na le bothata bo tloaelehileng ke hore theko e holimo haholo.
3, 'me e sebelisoa ho lisebelisoa tsa luminescent
Bophahamo bo boholo ba lekhalo le otlolohileng la aluminium nitride (AlN) ke 6.2 eV, e nang le katleho e phahameng ea phetoho ea photoelectric ha e bapisoa le semiconductor e sa tobang ea bandgap.AlN Joalo ka lebone la bohlokoa le leputsoa le lisebelisoa tse ntšang mabone a UV, e sebelisoa ho UV / deep UV emitting diode, UV laser diode le UV detector.Ho feta moo, AlN e ka theha litharollo tse tiileng tse tsoelang pele ka li-nitride tsa sehlopha sa III tse kang GaN le InN, 'me motsoako oa eona oa ternary kapa quaternary o ka tsoela pele ho fetola lekhalo la sehlopha sa lona ho tloha ho tse bonahalang ho ea ho lihlopha tse tebileng tsa ultraviolet, e leng se etsang hore e be thepa ea bohlokoa e sebetsang hantle ea luminescent.
4, e sebelisoang ho lisebelisoa tsa substrate
Likristale tsa AlN ke karoloana e loketseng bakeng sa GaN, AlGaN hammoho le lisebelisoa tsa AlN epitaxial.Ha e bapisoa le sapphire kapa SiC substrate, AlN e na le mocheso o mongata oa GaN, o na le ts'ebelisano e phahameng ea lik'hemik'hale, 'me e fokotseha khatello ea kelello pakeng tsa substrate le epitaxial layer.Ka hona, ha kristale ea AlN e sebelisoa e le karolo ea GaN epitaxial substrate, e ka fokotsa haholo sekhahla sa sekoli ho sesebelisoa, ea ntlafatsa ts'ebetso ea sesebelisoa, 'me e na le tebello e ntle ea kopo ha ho lokisoa mocheso o phahameng, maqhubu a phahameng le matla a phahameng a elektronike. lisebelisoa.
Ho phaella moo, AlGaN epitaxial material substrate e nang le kristale ea AlN e le karolo e phahameng ea aluminium (Al) e ka boela ea fokotsa ka katleho sekhahla sa sekoli ho nitride epitaxial layer, 'me ea ntlafatsa haholo ts'ebetso le bophelo ba tšebeletso ea sesebelisoa sa nitride semiconductor.Li-detectors tsa boleng bo holimo tsa letsatsi le letsatsi tse thehiloeng ho AlGaN li sebelisitsoe ka katleho.
5, e sebelisoang ka lirafshoa le thepa ea refractory
Aluminium nitride e ka sebelisoa ho sintering ea lirafshoa tsa moralo, li-ceramics tsa aluminium nitride tse lokiselitsoeng, eseng feela thepa e ntle ea mochine, matla a ho phutha a phahame ho feta Al2O3 le BeO ceramics, boima bo phahameng, empa hape le mocheso o phahameng le ho hanyetsa kutu.U sebelisa AlN ceramic ceramic resistance and corrosion resistance, e ka sebelisoa ho etsa likarolo tse hananang le mocheso o phahameng joalo ka crucible le Al evaporation plate.Ntle le moo, li-ceramics tse hloekileng tsa AlN ke likristale tse bonaletsang tse se nang 'mala, tse nang le thepa e ntle ea optical,' me li ka sebelisoa e le fensetere ea mocheso o phahameng oa mocheso le mohatsela o thibelang mocheso bakeng sa lirafshoa tse pepeneneng tse etsang lisebelisoa tsa elektroniki tsa optical.
6. Likopano
Epoxy resin / AlN composite material, e le thepa ea ho paka, e hloka conductivity e ntle ea mocheso le bokhoni ba ho qhala mocheso, 'me tlhokahalo ena e ntse e eketseha.Joaloka lisebelisoa tsa polymer tse nang le lik'hemik'hale tse ntle tsa lik'hemik'hale le botsitso ba mechine, epoxy resin e bonolo ho e phekola, ka tekanyo e tlaase ea ho fokotseha, empa mocheso oa mocheso ha o phahame.Ka ho kenyelletsa AlN nanoparticles e nang le conductivity e ntle ea mocheso ho epoxy resin, conductivity ea mocheso le matla li ka ntlafatsoa ka katleho.
