Fa'amatalaga o oloa
Aluminum Nitride, formula AlN, o se mea fou i le aiga sima faʻapitoa. E ui o lona mauaina na tupu i le silia ma le 100 tausaga talu ai, ua atiaeina e avea ma oloa faʻapisinisi faʻatasi ma meatotino pulea ma toe gaosia i totonu o le 20 tausaga talu ai.
Alumini nitride o loʻo i ai se fausaga tioata hexagonal ma o se mea faʻapipiʻi faʻapipiʻi. E mana'omia le fa'aogaina o mea fa'apipi'i ma le oomi vevela e maua ai se mea fa'atekinisi mafiafia. O meafaitino e mautu i le maualuga tele o le vevela i totonu o le ea. I le ea, o le faʻamaʻiina o luga e amata ile 700°C. O se vaega o le alumini oxide fomu e puipuia ai mea e oo atu i le 1370°C. I luga aʻe o lenei vevela e tupu tele faʻamaʻi. Alumini nitride e mautu i le hydrogen ma carbon dioxide ea e oo atu i le 980°C.
O mea e solo lemu i minerale acids e ala i osofaʻiga tuaoi o saito, ma i alkalis malosi e ala i osofaʻiga i luga o fatu nitride alumini. Ole mea e fa'asusu lemu ile vai. O le tele o fa'aoga o lo'o iai nei i totonu o le vaega fa'aeletonika lea e taua tele ai le fa'avevelaina o le vevela. O lenei mea e fiafia i ai o se mea e le oona i le beryllia. O lo'o avanoa auala fa'ameamea e fa'ataga ai le AlN e fa'aoga e suitulaga i le alumina ma le BeO mo le tele o mea fa'aeletoroni
