CAS 24304-00-5 Nano Aluminium Nitride AlN hmoov
Nta ntawm AlN hmoov:
AlN hmoov muaj siab purity, nqaim ntau particle loj tis, loj dua qhov chaw nto, qis bulk ntom thiab zoo shaping txhaj tshuaj molding zog.2. Aluminium nitride nano hmoov yog siv rau hauv cov khoom sib xyaw, thiab nws muaj kev sib tw zoo nrog cov semiconductor silicon thiab nws cov kev sib txuas zoo sib xws txhim kho cov khoom siv hluav taws xob thiab thermal conductivity ntawm cov khoom sib xyaw.
Specification ntawm AlN hmoov:
| Yam khoom | Purity | APS | Xim | Kev ceev ceev | Daim ntawv Crystallographic | cov ntsiab lus oxygen | Txoj kev ua | SSA |
| XL-AlN hmoov | 99% | 50nm ua | Grey | 0.05g / cm3 | Hexagonal qauv | 0.8% | Plasma CVD | 105 m2/g |
Daim ntawv thov ntawm AlN hmoov:
AlN hmoov siv los txhim kho kev ua tau zoo ntawm epoxy resin Nyob rau hauv Aluminium nitride nanopowder thiab epoxy resin system, thaum cov ntsiab lus ntawm Aluminium nitride nanoparticle nce mus txog 1% ~ 5%, iav-hloov kub nce thiab module ntawm elasticity mus txog qhov siab tshaj plaws tus nqi.Qhov ntxiv ntawm Aluminium nitride nanopowder rau epoxy resin compound cov ntaub ntawv yog txawv kiag li los ntawm kev ntxiv ntawm Aluminium nitride micro grain hauv cov qauv.AlN hmoov feem ntau yog ntxiv los ua ib hom kev txhawb nqa thiab feem ntau faib ntawm cov chains ntawm cov khoom siv polymer.Rau kev sib koom tes tsis txaus ntawm qhov chaw thiab thaj chaw loj, AlN hmoov qhia tau hais tias muaj zog heev.Lub caij no, ib feem ntawm Aluminium nitride nanoparticles nplej tau muab faib rau hauv qhov sib nrug ntawm cov saw hlau polymer.Muab piv rau Aluminium nitride micro grain, AlN hmoov muaj cov kua dej zoo heev thiab tuaj yeem txhim kho kev siv zog, tenacity thiab tractility ntawm epoxy resin.
AlN hmoov siv rau cov khoom siv hluav taws xob kub
Lub silica gel compounded nrog AlN hmoov, uas muaj super thermal conductivity, muab zoo heev thermal conductivity, hluav taws xob rwb thaiv tsev, dav ua hauj lwm kub ntawm hluav taws xob rwb thaiv tsev (-60 ℃ ~ -200 ℃), qis thickness thiab zoo ua hauj lwm kev ua tau zoo, thiab yuav ua tau dav. siv nyob rau hauv lub thermal kis nruab nrab ntawm hluav taws xob tivthaiv los txhim kho kev ua hauj lwm efficiency, xws li CPU radiator muab tub lim, high-power audion, controllable Silicon Cheebtsam, diode, thermal kis nruab nrab nyob rau hauv seam thiab hais txog.
AlN hmoov tuaj yeem txhim kho cov thermal conductivity ntawm cov yas.Los ntawm kev ntxiv Aluminium nitride nanoparticles rau yas raws li qhov kev faib ua feem ntawm 5% ~ 10% hauv huab hwm coj, peb tuaj yeem ua kom cov thermal conductivity ntawm yas los ntawm 0.3W / (mk) mus rau 0.5W / (mk), 16 zaug ntxiv.Piv nrog rau cov thermal conduction stuffing (alumina lossis magnesia) hauv kev ua lag luam, nws tuaj yeem txhim kho cov khoom siv hluav taws xob nrog cov khoom me me.Tam sim no, cov tuam txhab lag luam muaj feem xyuam tau yuav AlN hmoov hauv pawg thiab cov tshiab-hom nano tshav kub conduction yas yuav raug tso tawm rau kev ua lag luam.
AlN hmoov ua haujlwm zoo heev hauv silicon dioxide thiab nyiam tawg hauv cov roj hmab.Nyob rau hauv qhov kev pom zoo ntawm kev ua kom tsis muaj qhov sib txawv ntawm kev ua haujlwm ntawm cov roj hmab, (kev sim ua pov thawj tias nws tuaj yeem txhim kho kev ua haujlwm ntawm cov roj hmab), nws tuaj yeem txhim kho cov cua sov ntawm cov roj hmab thiab yuav tsis txo qis viscosity zoo li lwm cov oxides thaum ntxiv cov txheej txheem. , thiab tsuas yog tsawg heev yuav tsum tau.Nws tau dav siv rau tub rog, aviation thiab cov ntaub ntawv engineering.
