I-aluminum nitride ceramic esetshenziselwa izingxenye ezisusa ukushisa nezingxenye ezimelana nokugqwala
Izinzuzo Ze-Aluminium Nitride Ceramics
1. High conductivity ezishisayo
Izitsha zobumba ze-aluminum nitride zinokusebenza okuphezulu kwe-thermal, futhi ukuguquguquka kwazo okushisayo kuphezulu njengokungu-220 ~ 240W/m·K, okuphindwe izikhathi ezingu-2 ~ 3 kunezobumba ze-silicate. Lokhu kuhanjiswa okuphezulu kwe-thermal kungaxazulula ngokuphumelelayo inkinga yokukhishwa kokushisa kwemishini kagesi, ngakho-ke isetshenziswa kabanzi embonini ye-electronics.
2. High insulation
I-Aluminium nitride ceramic iyisici esihle kakhulu sokuvikela esine-resistivity ephezulu kanye ne-dielectric constant. Lokhu kusho ukuthi ingakwazi ukuhlukanisa ngokuphumelelayo izakhi zesifunda futhi ivimbele izifunda ezimfushane zesifunda kanye nokushisa ngokweqile.
3. Ukumelana nokugqwala okuphezulu
I-Aluminium nitride ceramics inokumelana okuhle nokugqwala kuma-asidi amaningi, izisekelo nezincibilikisi zemvelo. Lokhu kwenza kube ukukhetha okuhle embonini yamakhemikhali neyemithi.
4. Amandla aphezulu emishini
Izitsha zobumba ze-aluminum nitride zinamandla amakhulu okusebenza, futhi amandla azo okugoba nokuqina kokuphuka kungu-800MPa no-10-12mpa ·m1/2, ngokulandelanayo. Lawa mandla aphezulu kanye nobunzima obuphakeme buwenza asetshenziswe kabanzi kumathuluzi okusika, izinkambu zezingxenye ezingagqoki.
Ukusetshenziswa kwe-Aluminium Nitride Ceramics
1. Imboni yezogesi
Embonini ye-elekthronikhi, i-aluminium nitride ceramics isetshenziswa kakhulu ukwenza amandla aphezulu kanye namadivayisi kagesi amvamisa ephezulu. Ngenxa ye-conductivity yayo ephezulu yokushisa kanye nokusebenza okuhle kakhulu kwe-insulation, ixazulula ngokuphumelelayo inkinga yokuchithwa kokushisa kwemishini ye-elekthronikhi, futhi iqinisekisa ukwethembeka okuphezulu kwemishini kagesi. Ngaphezu kwalokho, i-aluminium nitride ceramics ingasetshenziswa futhi ukwenza amadivaysi e-microwave kanye namadivayisi we-millimeter wave, ukuthuthukisa ukusebenza nokuzinza kwemishini yokuxhumana.
2. Imboni yezimoto
Embonini yezimoto, i-aluminium nitride ceramics isetshenziswa kakhulu ukwenza izingxenye zenjini, ama-cylinder liners nama-brake pads. Ngenxa yokumelana nokugqwala okuphezulu namandla amakhulu emishini, ingagcina ukusebenza kahle emazingeni okushisa aphezulu nasezindaweni ezinokhahlo isikhathi eside. Ngaphezu kwalokho, i-aluminium nitride ceramics ingasetshenziswa futhi ukwenza izinzwa zegesi ukuze kutholwe izingxenye eziyingozi ekukhishweni kwemoto futhi kunikeze isisekelo sokwenza injini isebenze kahle.
3. Inkambu ye-Optical
Emkhakheni we-optics, i-aluminium nitride ceramics inokuhamba okuphezulu kwe-thermal kanye nokuzinza okuhle kakhulu kokushisa, ngakho-ke asetshenziswa kabanzi ekwenzeni ama-lasers asebenzayo, amafilimu optical kanye ne-optical fiber nezinye izingxenye ezibalulekile ze-optical. Ngaphezu kwalokho, izitsha zobumba ze-aluminium nitride zingasetshenziswa futhi ukwenza amathuluzi anembayo njengama-spectrometer, izinzwa zokushisa okuphezulu nezitholi ze-infrared, ukuthuthukisa ukunemba nokuthembeka kwezilinganiso zokubona.
4. Inkambu ye-semiconductor
Ipuleti lokushisisa emshinini we-semiconductor lisebenzisa izici ze-thermal conductivity ephezulu, ukumelana ne-asidi ne-alkali kanye nokumelana nokugqoka kwe-aluminium nitride ceramics. Kodwa-ke, ipuleti lokufudumeza i-aluminium nitride lisesesigabeni socwaningo nentuthuko e-China, kodwa liyingxenye ebalulekile ekukhiqizeni ama-chip.
