Haɗe tare da cikakkiyar fa'idodin aikin Al2O3 na al'ada da kayan ƙasa na BeO, yumbu Nitride (AlN) yumbu, wanda ke da haɓakar haɓakar thermal (monocrystal's theoretical theormal conductivity shine 275W / m ▪k, polycrystal's theoretical theormal conductivity shine 70 ~ 210W) ) , ƙananan dielectric akai-akai, ƙimar haɓakar haɓakar thermal wanda ya dace da siliki guda ɗaya, da kyawawan kaddarorin wutar lantarki, abu ne mai kyau don abubuwan kewayawa da marufi a cikin masana'antar microelectronics.Hakanan abu ne mai mahimmanci don abubuwan haɗin ginin yumbu mai zafin jiki saboda kyawawan kaddarorin inji mai zafin jiki, kaddarorin thermal da kwanciyar hankali na sinadarai.
The theoretical yawa na AlN ne 3.26g/cm3, da MOHS taurin ne 7-8, da dakin-zazzabi resistivity ne mafi girma fiye da 1016Ωm, da thermal expansivity ne 3.5 × 10-6 / ℃ (ɗakin zafin jiki na 200 ℃).Tsaftataccen yumbu na AlN ba su da launi da bayyane, amma za su kasance launuka daban-daban kamar launin toka, fari mai launin toka ko rawaya mai haske, saboda datti.
Baya ga haɓakar haɓakar thermal, AlN ceramics kuma suna da fa'idodi masu zuwa:
1. Kyakkyawan rufin lantarki;
2. Similar thermal fadada coefficient tare da silicon monocrystal, mafi girma da kayan kamar Al2O3 da BeO;
3. Babban ƙarfin injina da irin ƙarfin daidaitawa tare da tukwane na Al2O3;
4. Matsakaicin dielectric akai-akai da asarar dielectric;
5. Idan aka kwatanta da BeO, thermal conductivity na AlN tukwane ba shi da tasiri da zafin jiki, musamman sama da 200 ℃;
6. Babban zafin jiki da juriya na lalata;
7. Mara guba;
8. Za a yi amfani da semiconductor masana'antu, sinadaran karafa masana'antu da sauran masana'antu filayen.
