Aluminium nitride ceramic faʻaaogaina mo vaega faʻafefe vevela ma vaega faʻafefe
Tulaga lelei ole Aluminium Nitride Ceramics
1. maualuga conductivity vevela
Aluminum nitride ceramics e maualuga le conductivity vevela, ma o latou conductivity vevela e maualuga e pei o 220 ~ 240W / m · K, lea e 2 ~ 3 taimi o silicate ceramics. O lenei maualuga maualuga o le vevela e mafai ona foia lelei ai le faʻafitauli o le faʻafefe o le vevela o mea faʻaeletoroni, o lea e faʻaaogaina lautele ai i le alamanuia eletise.
2. Insulation maualuga
Aluminium nitride ceramic o se mea sili ona lelei insulating ma maualuga resistivity ma dielectric tumau. O lona uiga e mafai ona fa'a'ese'ese lelei elemene ta'amilosaga ma puipuia fa'alavelave fa'afuase'i ma le vevela.
3. Tete'e maualuga corrosion
Aluminium nitride ceramics o loʻo i ai le faʻafefeteina lelei i le tele o vailaʻau, faʻavae ma solvents organic. O le mea lea ua avea ai ma se filifiliga lelei i le vailaʻau ma vailaʻau.
4. Malosi faʻainisinia maualuga
Aluminium nitride ceramics e maualuga le malosi faʻainisinia, ma o latou malosi punou ma gau gau o 800MPa ma 10-12mpa · m1 / 2, faasologa. O lenei malosi maualuga ma le maaa maualuga e faʻaaogaina lautele i meafaigaluega tipi, vaega faʻafefete faʻaofuofu fanua.
Fa'aaogāga o le Aluminium Nitride Ceramics
1. Alamanuia faaeletonika
I totonu o mea tau eletise, alumini nitride ceramics e masani ona faʻaaogaina e gaosia ai le malosi maualuga ma le tele o masini eletise. Ona o le maualuga o le faʻaogaina o le vevela ma le faʻaogaina lelei o le faʻaogaina, e foia lelei ai le faʻafitauli o le faʻafefe o le vevela o mea faʻaeletoroni, ma faʻamaonia ai foi le maualuga o le faʻatuatuaina o masini eletise. E le gata i lea, e mafai foi ona faʻaogaina le alumini nitride ceramics e gaosia ai masini microwave ma masini galu millimeter, faʻaleleia le faʻatinoga ma le mautu o mea tau fesoʻotaʻiga.
2. Alamanuia tau taavale
I totonu o fale taʻavale, alumini nitride ceramics e masani ona faʻaaogaina e gaosia ai vaega afi, paʻu paʻu ma paʻu taofi. Ona o le maualuga o le corrosion resistance ma le maualuga o le malosi faʻainisinia, e mafai ona faʻatumauina lelei le faʻatinoga i le maualuga o le vevela ma siosiomaga faigata mo se taimi umi. E le gata i lea, e mafai foʻi ona faʻaogaina le alumini nitride ceramics e gaosia ai masini kesi e iloa ai vaega leaga i le taʻavale taʻavale ma maua ai se faʻavae mo le faʻaogaina o afi.
3. fanua fa'apitoa
I le fanua o mata, alumini nitride ceramics o loʻo i ai le maualuga o le vevela ma le faʻamautuina lelei o le vevela, o lea e faʻaaogaina lautele ai i le gaosiga o lasers maualuga, ata tifaga ma fiber opitika ma isi vaega autu autu. E le gata i lea, e mafai foi ona faʻaogaina le alumini nitride ceramics e gaosia ai meafaifaʻaili saʻo e pei o spectrometers, maualuga vevela masini ma infrared detectors, faʻaleleia le saʻo ma le faʻamaoni o fua faʻatatau.
4. Semiconductor fanua
O le mea faʻamafanafana i luga o le masini semiconductor e faʻaaogaina ai uiga o le maualuga o le vevela, faʻamaʻi ma le alkali ma le faʻaogaina o le alumini nitride ceramics. Ae ui i lea, o le aluminium nitride faʻamafanafana ipu o loʻo i ai pea i le suʻesuʻega ma le atinaʻeina i Saina, ae o se vaega taua tele i le gaosiga o masini.
