Aluminiyamu nitride ceramic yomwe imagwiritsidwa ntchito pochotsa kutentha ndi zida zolimbana ndi dzimbiri
Ubwino Wa Aluminium Nitride Ceramics
1. High matenthedwe madutsidwe
Zida za aluminiyamu za nitride zimakhala ndi matenthedwe apamwamba kwambiri, ndipo kutenthetsa kwawo kumafika pa 220 ~ 240W/m·K, zomwe ndi 2 ~ 3 kuwirikiza kawiri kuposa zoumba za silicate. Kutentha kwapamwamba kumeneku kumatha kuthetsa bwino vuto la kutentha kwa zipangizo zamagetsi, choncho amagwiritsidwa ntchito kwambiri pamakampani amagetsi.
2. Kutentha kwakukulu
Aluminium nitride ceramic ndi chinthu chabwino kwambiri chotetezera chomwe chimakhala ndi resistivity yayikulu komanso dielectric mosalekeza. Izi zikutanthauza kuti imatha kudzipatula bwino zigawo zadera ndikuletsa mabwalo amfupi ndi kutenthedwa.
3. High dzimbiri kukana
Aluminium nitride ceramics ali ndi kukana kwa dzimbiri kwa ma acid ambiri, maziko ndi zosungunulira za organic. Izi zimapangitsa kukhala chisankho choyenera m'makampani opanga mankhwala ndi mankhwala.
4. Mphamvu zamakina apamwamba
Aluminium nitride ceramics ali ndi mphamvu zamakina apamwamba, ndipo mphamvu yopindika ndi kulimba kwa fracture ndi 800MPa ndi 10-12mpa ·m1/2, motsatana. Kulimba kwakukulu kumeneku komanso kuuma kwakukulu kumapangitsa kuti azigwiritsidwa ntchito kwambiri pazida zodulira, magawo osagwira ntchito.
Kugwiritsa Ntchito Aluminium Nitride Ceramics
1. Makampani opanga zamagetsi
M'makampani amagetsi, aluminium nitride ceramics amagwiritsidwa ntchito kwambiri popanga zida zamagetsi zamagetsi komanso zamagetsi zamagetsi. Chifukwa cha kutentha kwake kwapamwamba kwambiri komanso ntchito yabwino yotchinjiriza, imathetsa bwino vuto la kutentha kwa zipangizo zamagetsi, komanso imatsimikizira kudalirika kwakukulu kwa zipangizo zamagetsi. Kuphatikiza apo, zoumba za aluminiyamu za nitride zitha kugwiritsidwanso ntchito kupanga zida za ma microwave ndi zida zamamilimita mafunde, kuwongolera magwiridwe antchito ndi kukhazikika kwa zida zoyankhulirana.
2. Makampani opanga magalimoto
M'makampani amagalimoto, aluminium nitride ceramics amagwiritsidwa ntchito makamaka popanga zida za injini, zomangira za silinda ndi ma brake pads. Chifukwa cha kukana kwake kwa dzimbiri komanso mphamvu zamakina apamwamba, imatha kukhalabe ndi magwiridwe antchito abwino pa kutentha kwambiri komanso malo ovuta kwa nthawi yayitali. Kuphatikiza apo, zitsulo za aluminiyamu za nitride zitha kugwiritsidwanso ntchito kupanga masensa a gasi kuti azindikire zinthu zovulaza muutsi wamagalimoto ndikupereka maziko okhathamiritsa injini.
3. Optical munda
M'munda wa optics, zoumba za aluminiyamu nitride zimakhala ndi matenthedwe apamwamba kwambiri komanso kukhazikika kwamafuta abwino kwambiri, motero zimagwiritsidwa ntchito kwambiri popanga ma lasers apamwamba, mafilimu owoneka bwino ndi ulusi wamagetsi ndi zida zina zofunika kwambiri. Kuphatikiza apo, zoumba za aluminiyamu za nitride zitha kugwiritsidwanso ntchito kupanga zida zolondola monga ma spectrometer, masensa otenthetsera kutentha ndi zowunikira za infuraredi, kuwongolera kulondola komanso kudalirika kwamiyezo ya kuwala.
4. Munda wa semiconductor
Chipinda chotenthetsera pazida za semiconductor chimagwiritsa ntchito mawonekedwe amafuta apamwamba kwambiri, kukana kwa asidi ndi alkali komanso kukana kwa aluminium nitride ceramics. Komabe, mbale yotenthetsera ya aluminium nitride idakali mu kafukufuku ndi chitukuko ku China, koma ndi gawo lofunika kwambiri pakupanga chip.
