Hoʻohui pū ʻia me nā pono hana piha o nā mea substrate Al2O3 a me BeO, Aluminum Nitride(AlN) ceramic, he kiʻekiʻe ka thermal conductivity (monocrystal's theoretical thermal conductivity he 275W/m▪k,polycrystal's theoretical thermal conductivity he 70~210W/mk. ), ʻo ka haʻahaʻa dielectric mau, thermal expansion coefficient i hoʻohālikelike ʻia me ka silika aniani hoʻokahi, a me nā waiwai insulation uila maikaʻi, he mea kūpono no nā substrates kaapuni a me ka hoʻopili ʻana i ka ʻoihana microelectronics.He mea koʻikoʻi nō hoʻi ia no nā ʻāpana seramika kiʻekiʻe ma muli o ka maikaʻi kiʻekiʻe kiʻekiʻe o nā ʻano mechanical, nā waiwai wela a me ke kūpaʻa kemika.
He 3.26g/cm3 ka mānoanoa theoretical o AlN, ʻo ka paʻakikī MOHS he 7-8, ʻoi aku ka nui o ka resistivity lumi-mehana ma mua o 1016Ωm, a ʻo ka expansivity thermal he 3.5 × 10-6/℃ (ke mahana lumi o 200 ℃).ʻAʻole waihoʻoluʻu a ʻālohilohi nā seramika AlN maʻemaʻe, akā he mau kala like ʻole e like me ka hina, hina keʻokeʻo a i ʻole melemele māmā, ma muli o nā haumia.
Ma kahi o ka conductivity thermal kiʻekiʻe, loaʻa i nā seramika AlN nā mea maikaʻi aʻe:
1. Hoʻopili uila maikaʻi;
2. ʻOi aku ka nui o nā mea like me Al2O3 a me BeO;
3. ʻO ka ikaika mechanical kiʻekiʻe a me ka ikaika flexural like me Al2O3 ceramics;
4. ʻO ka dielectric maʻamau a me ka poho dielectric;
5. Hoʻohālikelike ʻia me BeO, ʻoi aku ka liʻiliʻi o ka conductivity thermal o AlN ceramics e ka mahana, ʻoi aku ma luna o 200 ℃;
6. Kūleʻa wela kiʻekiʻe a me ka pale ʻana i ka corrosion;
7. Non-toxic;
8. E hoʻohana ʻia i ka ʻoihana semiconductor, ʻoihana metala kemika a me nā ʻoihana ʻē aʻe.
