Uhujije hamwe nibikorwa byiza byimikorere ya gakondo ya Al2O3 na BeO substrate, Aluminium Nitride (AlN) ceramic, ifite ubushyuhe bwinshi bwumuriro (monocrystal's theoretique yumuriro ni 275W / m▪k ， polycrystal ya tewolojiya yubushyuhe ni 70 ~ 210W / m▪k ).Nibikoresho byingenzi byubushyuhe bwo hejuru bwububiko bwa ceramic bitewe nubushyuhe bwiza bwo hejuru bwubukanishi, imiterere yubushyuhe hamwe nubushakashatsi bwimiti.
Ubucucike bwa theoretical ya AlN ni 3.26g / cm3, ubukana bwa MOHS ni 7-8, kurwanya ubushyuhe bwicyumba burenze 1016Ωm, naho ubushyuhe bwumuriro ni 3.5 × 10-6 / ℃ (ubushyuhe bwicyumba cya 200 ℃).Ububiko bwiza bwa AlN butagira ibara kandi bubonerana, ariko bwaba amabara atandukanye nkimvi, imvi zijimye cyangwa umuhondo wijimye, kubera umwanda.
Usibye ubushyuhe bwinshi bwo hejuru, Ceramics ya AlN nayo ifite ibyiza bikurikira:
1. Gukoresha amashanyarazi meza;
2. Coefficient isa niyaguka yubushyuhe hamwe na silicon monocrystal, iruta ibikoresho nka Al2O3 na BeO;
3. Imbaraga zikoreshwa cyane hamwe nimbaraga zisa na ceramics ya Al2O3;
4. Kugereranya dielectric ihoraho no gutakaza dielectric;
5. Ugereranije na BeO, ubushyuhe bwumuriro wa AlN ceramics ntabwo bugira ingaruka kubushyuhe, cyane cyane hejuru ya 200 ℃;
6. Kurwanya ubushyuhe bwinshi no kurwanya ruswa;
7. Ntabwo ari uburozi;
8. Koresha inganda ziciriritse, inganda za metallurgie nizindi nganda.
