Aluminium Nitride, formula AlN, yog cov khoom siv tshiab hauv tsev neeg ceramics. Thaum nws qhov kev tshawb pom tau tshwm sim ntau dua 100 xyoo dhau los, nws tau tsim los rau hauv cov khoom lag luam uas muaj peev xwm tswj tau thiab rov tsim dua tshiab hauv 20 xyoo dhau los.
Aluminium nitride muaj cov qauv siv lead ua hexagonal thiab yog cov khoom siv sib xyaw ua ke. Kev siv cov khoom siv sintering thiab kub nias yog tsim los tsim cov khoom siv qib siab. Cov khoom yog ruaj khov rau kub heev nyob rau hauv inert atmospheres. Nyob rau hauv huab cua, nto oxidation pib tshaj 700 ° C. Ib txheej ntawm aluminium oxide cov ntaub ntawv uas tiv thaiv cov khoom mus txog 1370 ° C. Saum toj no kub tej oxidation tshwm sim. Aluminium nitride yog ruaj khov nyob rau hauv hydrogen thiab carbon dioxide atmospheres txog 980 ° C.
Cov khoom dissolves maj mam nyob rau hauv mineral acids los ntawm grain ciam nres, thiab nyob rau hauv muaj zog alkalis los ntawm kev tawm tsam ntawm txhuas nitride nplej. Cov khoom siv hydrolyzes maj mam hauv dej. Cov ntawv thov tam sim no feem ntau yog nyob rau hauv cov khoom siv hluav taws xob uas qhov kev tshem tawm cua sov yog qhov tseem ceeb. Cov khoom siv no yog qhov txaus siab ua lwm yam tsis muaj tshuaj lom rau beryllia. Metallization txoj kev muaj los tso cai rau AlN siv rau qhov chaw ntawm alumina thiab BeO rau ntau daim ntawv thov hluav taws xob
