Chiyambi cha aluminium nitride

Aluminiyamu nitride (AlN) ndi woyera kapena imvi nonmetallic pawiri ndi molecular kulemera kwa 40.98, malo osungunuka 2200 ℃, kuwira mfundo 2510 ℃, ndi kachulukidwe 3.26g/cm³.Aluminiyamu nitride ndi zinthu zatsopano za ceramic zomwe zimakhala ndi matenthedwe apamwamba kwambiri, kukana kutentha kwambiri, kukana kwa dzimbiri, kutchinjiriza kwakukulu komanso kukana kwamphamvu kwambiri, komwe kumagwiritsidwa ntchito kwambiri pamagetsi, mphamvu yamagetsi, zakuthambo, zida zolondola ndi zina.

Makhalidwe a aluminium nitride

1. Thermal katundu:aluminiyamu nitride ali mkulu matenthedwe madutsidwe, wachiwiri kwa diamondi, ndipo angagwiritsidwe ntchito kwa nthawi yaitali pa kutentha kwambiri.

2. Mphamvu zamakina:aluminium nitride imakhala ndi kuuma kwakukulu komanso kukana kwabwino kovala.

3. Mphamvu zamagetsi: aluminium nitride ili ndi kutsekemera kwamagetsi kwabwino kwambiri.

4. Optical katundu:Aluminium nitride ili ndi mawonekedwe abwino kwambiri owoneka bwino, ndipo mawonekedwe ake owunikira ndi 200-2000nm, ma transmittance oposa 95%.

Kukonzekera njira ya aluminium nitride

Njira zokonzekera aluminium nitride makamaka ndi izi:

1. Njira yochepetsera Carbothermal:calcium carbonate ndi aluminiyamu zimasakanizidwa ndi ufa wa kaboni, zimatenthedwa mpaka 1500-1600 ℃ mu ng'anjo yophulika, kuti mpweya umakumana ndi mpweya kuti upangitse mpweya woipa, otsalawo amachitira ndi calcium carbonate kuti apange calcium ndi carbon dioxide, ndipo pamapeto pake amapeza aluminium. nitride.

2. Njira ya Direct nitriding:Sakanizani aluminiyamu kapena aluminiyamu mchere ndi ammonia, kuwonjezera mlingo woyenera wa ammonium kolorayidi kusintha pH mtengo, kupeza zovuta aluminium ion ndi ammonia ion, ndiyeno kutentha pa kutentha kwa 1000-1200 ℃, kuti ammonia kuwola kukhala mpweya ammonia. , ndipo potsiriza kupeza aluminium nitride.

3. Njira yakupopera:ndi mkulu mphamvu ion mtengo sputtering zotayidwa tetrachloride ndi nayitrogeni, zotayidwa tetrachloride amachita ndi nayitrogeni kupanga zotayidwa nitride pa kutentha kwambiri, pamene kusonkhanitsa kwaiye zotayidwa nitride ufa.

Kugwiritsa ntchito aluminium nitride

1. Malo amagetsi:Aluminiyamu nitride, monga mkulu matenthedwe madutsidwe zakuthupi, chimagwiritsidwa ntchito ma CD zipangizo zamagetsi, monga tchipisi semiconductor, transistors, etc.

2. Malo amagetsi:Kukana kutentha kwakukulu ndi kukana kwa dzimbiri kwa aluminium nitride kumapangitsa kuti igwiritsidwe ntchito kwambiri pamakina amagetsi, monga ma transfoma, ma capacitors ndi zina zotero.

3. Malo apamlengalenga:Aluminium nitride yamphamvu kwambiri, kuuma kwambiri komanso kukana kwamphamvu kwambiri kumapangitsa kuti izigwiritsidwa ntchito kwambiri m'munda wazamlengalenga, monga injini zandege, ma satelayiti ndi zina zotero.

4. Gawo la chida cholondola:kuwala kwapamwamba komanso mawonekedwe abwino kwambiri a aluminium nitride amachititsa kuti azigwiritsidwa ntchito kwambiri pazida zolondola, monga magalasi owoneka bwino, ma prisms, ndi zina zambiri.

Chiyembekezo cha chitukuko cha aluminium nitride

Ndi chitukuko chosalekeza cha sayansi ndi ukadaulo, aluminium nitride ngati mtundu watsopano wa zida za ceramic, gawo lake logwiritsira ntchito likupitilira kukula, kufunikira kwa msika kukuchulukiranso.M'tsogolomu, ndi kukonzanso kosalekeza kwa njira yokonzekera aluminium nitride ndi kuchepetsa mtengo, aluminium nitride idzagwiritsidwa ntchito m'madera ambiri.
