Aluminium nitride (AIN) yog renowned rau nws zoo heev thermal conductivity thiab tshwj xeeb hluav taws xob insulating zoo. Nws yog ib yam khoom siv ceramic siv nyob rau hauv ntau yam khoom siv hluav taws xob. Aluminium nitride ceramics tiv taus cov hlau molten, suav nrog tooj liab, lithium, thiab txhuas, ntxiv rau lawv cov thermal expansion thiab hluav taws xob insulating zog. Aluminium nitrideyog cov khoom siv tau zoo hauv ntau daim ntawv thov kev lag luam vim nws cov khoom siv tshuaj thiab lub cev.
Txawm li cas los xij, hauv kev tsim khoom, aluminium nitride feem ntau yog cais ua ob hom raws li cov txheej txheem sintering: prTsis muaj sintered aluminium nitride thiabkub nias aluminium nitride. Cov yam ntxwv thiab kev siv ntawm ob pawg no txawv heev.
Tsis muaj zog aluminium nitridesib tov high-purity txhuas nitride hmoov nrog ib tug me me ntawm ib tug sintering pab (xws li Y2O3), shaping cov sib tov rau hauv daim ntawv uas xav tau (piv txwv li, los ntawm qhuav nias los yog isostatic nias), thiab ces sintering nyob rau hauv ib tug kub kub (1800 ° C rau 2000 ° C) nyob rau hauv ib tug tiv thaiv inert cua (nitrogen). Cov txheej txheem no tso siab rau cov tshuaj tiv thaiv ntawm sintering pab thiab cov alumina tam sim no nyob rau saum npoo ntawm AlN hais, tsim cov kua theem uas txhawb nqa cov rearrangement thiab densification ntawm cov hais.
Nta:
Tus nqi qis: cov cuab yeej siv tau yooj yim, ua rau nws tsim nyog rau cov khoom loj loj.
Cov duab tsis yooj yim: nws tuaj yeem tsim ntau yam tsis xwm yeem zoo li qhov chaw thiab nyias daim hlau (xws li ceramic substrates).
Kev ua tau zoo: txawm hais tias nws tuaj yeem ua tau raws li qhov xav tau ntawm kev lag luam feem ntau, vim qhov tsis muaj qhov siab sab nraud, cov pores me me tau yooj yim tam sim no nyob rau hauv cov khoom, thiab qhov ceev yog feem ntau ntawm 97% thiab 99%.
Cov ntawv thov tseem ceeb:
Semiconductor ntim substrates (xws li LED thiab lub zog module substrates)
Kub dab dej thiab insulating gaskets
Corrosion-resistant thiab kub-resistant khoom Cheebtsam
Kub-pressed aluminium nitrideyog tsim los siv cov txheej txheem tshwj xeeb hu ua kub nias. Thaum lub sij hawm kub-kub sintering, unidirectional siab siab ntawm kaum los yog ntau pua megapascals yog siv rau cov khoom. Qhov kev sib koom ua ke ntawm qhov kub thiab txias siab yog qhov tseem ceeb rau kev ua tiav nws qhov kev ua tau zoo tshwj xeeb.
Nta:
Kev kub ceev heev: lub zog siab tawm ntawm qhov pores ntawm cov khoom, ua rau muaj qhov ntom ntom uas tuaj yeem ncav cuag tus nqi theoretical (＞ 99%).
Cov khoom siv zoo heev: piv rau cov pa sintered AlN, kub nias AlN muaj zog dua flexural thiab hardness.
Cov thermal conductivity zoo heev: vim qhov tsis tshua muaj porosity, phonon tawg yog txo, thiab nws cov thermal conductivity feem ntau ruaj khov thiab ze rau qhov txwv siab.
Kev txwv: tus nqi siab, kev ua haujlwm tsawg, thiab feem ntau tsuas yog cov duab geometric yooj yim xws li discs lossis blocks tuaj yeem ua tiav.
Cov ntawv thov tseem ceeb (high-end tshwj xeeb yuav tsum tau):
Thaum tshav kub kub dissipation thiab ntim ntawm high-power lasers
Tom ntej no-tiam high-power density xov tooj cua zaus/microwave li
Thaum tshav kub kub dissipation rau ultra-siab kev ntseeg tau hluav taws xob tshuab hauv aerospace teb
Cov cuab yeej tshawb fawb tshawb fawb lossis cov khoom siv ntsuas ntsuas ntsuas nyob rau hauv qee yam mob hnyav
Koj yuav tsum xaiv li cas?
Xaivtsis muaj zog aluminium nitrideYog tias: Koj ua haujlwm nrog cov khoom siv hluav taws xob hauv hluav taws xob (PCBs), LED cov dab dej kub, lossis cov khoom siv hluav taws xob yooj yim. Pressureless aluminium nitride yog qhov kev xaiv zoo tshaj plaws thiab muaj txiaj ntsig zoo.
Xaivkub nias aluminium nitrideYog tias: Koj qhov kev thov ib puag ncig yog qhov xav tau heev, xws li electrostatic chucks (ESCs) rau cov khoom siv semiconductor etching, high-performance laser bases, lossis precision structural Cheebtsam uas yuav tsum tau tiv taus siab mechanical stress. Qhov ceev thiab lub zog zoo ntawm kub nias aluminium nitride yog irreplaceable nyob rau hauv cov ntaub ntawv no.
