Intshayelelo ye-aluminiyam nitride

I-Aluminiyam nitride (AlN) yikhompawundi emhlophe okanye engwevu engeyiyo metallic enobunzima bemolekyuli obungama-40.98, indawo yokunyibilika eyi-2200℃, indawo yokubila eyi-2510℃, kunye noxinzelelo lwe-3.26g/cm³.I-Aluminiyam nitride yinto entsha ye-ceramic ene-conductivity ephezulu ye-thermal, ukumelana nobushushu obuphezulu, ukuxhathisa okuphezulu kwe-corrosion, ukugquma okuphezulu kunye nokuxhathisa okugqwesileyo, esetyenziswa kakhulu kwi-electronics, amandla ombane, i-aerospace, izixhobo ezichanekileyo kunye nezinye iindawo.

Iipropati ze-aluminiyam nitride

1. Iimpawu zobushushu:I-aluminium nitride ine-conductivity ephezulu ye-thermal, yesibini kuphela kwi-diamond, kwaye ingasetyenziselwa ixesha elide kumaqondo aphezulu.

2. Iimpawu zoomatshini:i-aluminiyam nitride inobulukhuni obuphezulu kunye nokumelana nokunxiba kakuhle.

3. Iimpawu zombane: i-aluminiyamu nitride ine-insulation egqwesileyo yombane.

4. Iimpawu zamehlo:I-Aluminium nitride ineempawu ezibalaseleyo ze-optical, kwaye uluhlu lwayo lokuhambisa ukukhanya luyi-200-2000nm, kunye nokuhanjiswa okungaphezulu kwe-95%.

Indlela yokulungiselela i-aluminiyam nitride

Iindlela zokulungiselela i-aluminiyam nitride ikakhulu zezi zilandelayo:

1. Indlela yokunciphisa iCarbothermal:i-calcium carbonate kunye ne-alumina ixutywe ne-carbon powder, ifudunyezwe kwi-1500-1600 ℃ kwiziko eliqhumayo, ukuze i-carbon iphendule kunye ne-oksijini ukuvelisa i-carbon dioxide, i-carbon eseleyo isabela nge-calcium carbonate ukuvelisa i-calcium kunye ne-carbon dioxide, kwaye ekugqibeleni ifumane i-aluminium. nitride.

2. Indlela ethe ngqo ye-nitriding:Xuba i-alumina okanye ityuwa ye-aluminiyam kunye ne-ammonia, yongeza inani elifanelekileyo le-ammonium chloride ukulungisa ixabiso le-pH, ufumane i-ion eyinkimbinkimbi ye-aluminiyam kunye ne-ammonia ion, kwaye ubushushu obuphezulu kwi-1000-1200℃, ukuze i-ammonia ibole ibe yigesi ye-ammonia. , kwaye ekugqibeleni ufumane i-aluminium nitride.

3. Indlela yokutshiza:ngamandla aphezulu e-ion beam sputtering i-aluminium tetrachloride kunye ne-nitrogen, i-aluminium tetrachloride iphendula kunye ne-nitrogen ukuvelisa i-aluminiyam nitride kwiqondo lokushisa eliphezulu, ngelixa iqokelela i-aluminiyam ye-nitride powder eyenziwe.

Ukusetyenziswa kwe-aluminiyam nitride

1. Indawo yombane:I-Aluminiyamu nitride, njengesixhobo esiphezulu se-thermal conductivity, isetyenziswa ngokubanzi kwipakethe yezixhobo zombane, ezifana ne-semiconductor chips, transistors, njl.

2. Indawo yamandla:Ukumelana nobushushu obuphezulu kunye nokumelana nokubola kwe-aluminium nitride kwenza ukuba isetyenziswe ngokubanzi kwiinkqubo zamandla, ezifana ne-transformers, i-capacitors njalo njalo.

3. Indawo ye-Aerospace:Amandla aphezulu e-aluminiyam nitride, ubulukhuni obuphezulu kunye nokumelana nokugqwesa okugqwesileyo kuyenza isetyenziswe ngokubanzi kwibala le-aerospace, njengeenjini zenqwelomoya, iisathelayithi njalo njalo.

4. Indawo yesixhobo esichanekileyo:Ukuhanjiswa kokukhanya okuphezulu kunye neempawu ezibalaseleyo ze-aluminium nitride zenza ukuba isetyenziswe ngokubanzi kwintsimi yezixhobo ezichanekileyo, ezinje ngeelensi zamehlo, iiprism, njl.

Ithemba lophuhliso lwe-aluminium nitride

Ngophuhliso oluqhubekayo lwesayensi kunye nobuchwepheshe, i-aluminium nitride njengohlobo olutsha lwezinto ze-ceramic, intsimi yesicelo sayo iyaqhubeka nokwandisa, imfuno yemarike nayo iyanda.Kwixesha elizayo, ngokuphuculwa okuqhubekayo kwenkqubo yokulungiselela i-aluminiyam nitride kunye nokunciphisa iindleko, i-aluminium nitride iya kusetyenziswa kwiinkalo ezininzi.
