Isingeniso ku-aluminium nitride

I-Aluminium nitride (AlN) iyinhlanganisela emhlophe noma empunga engeyona eyensimbi enesisindo semolekyuli esingu-40.98, iphoyinti lokuncibilika elingu-2200℃, indawo yokubila engu-2510℃, kanye nokuminyana okungu-3.26g/cm³.I-Aluminium nitride iyinsimbi entsha ye-ceramic ene-conductivity ephezulu yokushisa, ukumelana nokushisa okuphezulu, ukumelana nokugqwala okuphezulu, ukugqumisa okuphezulu kanye nokumelana okuhle kakhulu kwe-creep, esetshenziswa kakhulu ku-electronics, amandla kagesi, i-aerospace, izinsimbi ezinembayo neminye imikhakha.

Izici ze-aluminium nitride

1.Izakhiwo ezishisayo:I-aluminium nitride ine-conductivity ephezulu yokushisa, yesibili kuphela kwedayimane, futhi ingasetshenziswa isikhathi eside emazingeni okushisa aphezulu.

2. Izakhiwo zemishini:i-aluminium nitride inobulukhuni obuphezulu kanye nokumelana nokugqokwa okuhle.

3. Izakhiwo zikagesi: I-aluminium nitride ine-insulation kagesi enhle kakhulu.

4. Izakhiwo zokubuka:I-Aluminium nitride inezinto ezinhle kakhulu ze-optical, futhi ububanzi bayo bokudluliswa kokukhanya ngu-200-2000nm, nokudluliswa okungaphezulu kuka-95%.

Indlela yokulungiselela i-aluminium nitride

Izindlela zokulungiselela i-Aluminium nitride ikakhulukazi zimi kanje:

1. Indlela yokunciphisa i-Carbothermal:i-calcium carbonate ne-alumina kuxutshwe ne-carbon powder, kushisiswe ku-1500-1600 ℃ esithandweni somlilo, ukuze ikhabhoni ihlangane nomoya-mpilo ukukhiqiza i-carbon dioxide, i-carbon esele isabela ne-calcium carbonate ukukhiqiza i-calcium ne-carbon dioxide, futhi ekugcineni ithole i-aluminium. i-nitride.

2. Indlela ye-nitriding eqondile:Xuba i-alumina noma usawoti we-aluminium ne-ammonia, engeza inani elifanele le-ammonium chloride ukuze ulungise inani le-pH, uthole inkimbinkimbi ye-aluminium ion ne-ammonia ion, bese ushisisa ezingeni lokushisa eliphezulu ukuya ku-1000-1200℃, ukuze i-ammonia ibole ibe igesi ye-ammonia. , futhi ekugcineni uthole i-aluminium nitride.

3. Indlela ye-Sputtering:enamandla aphezulu e-ion beam sputtering aluminium tetrachloride ne-nitrogen, i-aluminium tetrachloride ihlangana ne-nitrogen ukukhiqiza i-aluminium nitride ezingeni lokushisa eliphezulu, kuyilapho iqoqa i-aluminium nitride powder ekhiqiziwe.

Ukusetshenziswa kwe-aluminium nitride

1. Inkambu ye-elekthronikhi:I-Aluminiyamu nitride, njengento ephezulu yokushibilika kwe-thermal, isetshenziswa kakhulu ekufakweni kwezinto zikagesi, njengama-semiconductor chips, ama-transistors, njll.

2. Inkambu yamandla:Ukumelana nokushisa okuphezulu nokumelana nokugqwala kwe-aluminium nitride kuyenza isetshenziswe kabanzi ezinhlelweni zamandla, njengama-transformers, ama-capacitor nokunye.

3. Inkambu ye-Aerospace:Amandla aphezulu e-aluminium nitride, ubulukhuni obuphezulu kanye nokumelana okuhle kakhulu kwe-creep kuyenza isetshenziswe kabanzi emkhakheni we-aerospace, njengezinjini zezindiza, amasathelayithi nokunye.

4. Inkambu yethuluzi lokunemba:ukudluliswa kokukhanya okuphezulu kanye nezakhiwo ezinhle kakhulu zokubona ze-aluminium nitride ziyenza isetshenziswe kabanzi emkhakheni wezinsimbi ezinembayo, njengamalensi optical, amaprism, njll.

Ithemba lokuthuthukiswa kwe-aluminium nitride

Ngokuthuthuka okuqhubekayo kwesayensi nobuchwepheshe, i-aluminium nitride njengohlobo olusha lwempahla ye-ceramic, inkambu yokusetshenziswa kwayo iyaqhubeka nokukhula, isidingo semakethe siyanda.Ngokuzayo, ngokuthuthuka okuqhubekayo kwenqubo yokulungiselela i-aluminium nitride kanye nokwehliswa kwezindleko, i-aluminium nitride izosetshenziswa emikhakheni eyengeziwe.
