Yakasanganiswa nezvakanakira kuita zvakanaka zvechinyakare Al2O3 uye BeO substrate zvinhu, Aluminium Nitride(AlN) ceramic, ine high conductivity yekupisa (monocrystal's theoretical thermal conductivity is 275W/m▪k,polycrystal's theoretical thermal conductivity is 70~k210W/m ▪ ), yakaderera dielectric inogara, kupisa kwekuwedzera koefficient inofananidzwa necrystal silicon imwe chete, uye yakanaka magetsi ekudzivirira zvivakwa, chinhu chakakodzera chedunhu substrates uye kurongedza muindasitiri yemicroelectronics.Icho chinhu chakakoshawo chepamusoro tembiricha yechimiro checeramic zvikamu nekuda kweiyo yakanaka yepamusoro tembiricha michina zvivakwa, zvinopisa zvimiro uye kugadzikana kwemakemikari.
Theoretical density yeAlN ndeye 3.26g/cm3, iyo MOHS kuomarara i7-8, kamuri-tembiricha resistivity yakakura kupfuura 1016Ωm, uye kuwedzera kwekupisa kuri 3.5 × 10-6/℃ (tembiricha yekamuri ye200 ℃).Yakachena AlN ceramics haina ruvara uye yakajeka, asi ingadai iri mavara akasiyana segrey, greyish chena kana yero, nekuda kwetsvina.
Kuwedzera kune yakakwira yekupisa conductivity, AlN ceramics zvakare ine zvinotevera zvakanakira:
1. Kuvhara kwemagetsi kwakanaka;
2. Similar thermal kuwedzera coefficient nesilicon monocrystal, yepamusoro kune zvinhu zvakadai Al2O3 uye BeO;
3. High mechanical simba uye yakafanana flexural simba neAl2O3 ceramics;
4. Moderate dielectric nguva dzose uye dielectric kurasikirwa;
5. Kuenzaniswa neBeO, iyo yekupisa kweAlN ceramics haina kukanganiswa nekupisa, kunyanya pamusoro pe200 ℃;
6. High tembiricha kuramba uye ngura kuramba;
7. Kwete-chepfu;
8. Ishandiswe kune semiconductor indasitiri, makemikari metallurgy indasitiri uye mamwe maindasitiri minda.
