Aluminom nitride, usoro AlN, bụ ihe ọhụrụ na ezinụlọ seramiki teknụzụ. Ọ bụ ezie na nchoputa ya mere ihe karịrị 100 afọ gara aga, emepụtara ya ka ọ bụrụ ngwaahịa a na-ere ahịa nke nwere njikwa na mmeghari n'ime afọ 20 gara aga.
Aluminom nitride nwere usoro kristal hexagonal na ọ bụ ihe ejikọtara ọnụ. A chọrọ iji ihe enyemaka na-ekpo ọkụ na ịpị ọkụ iji mepụta ihe ọkwa nkà na ụzụ dị ukwuu. Ihe ahụ kwụsiri ike ruo oke okpomọkụ na ikuku inert. N'ikuku, oxidation elu na-amalite n'elu 700 Celsius. Otu oyi akwa nke aluminum oxide na-etolite nke na-echebe ihe ahụ ruo 1370 ° C. N'elu okpomọkụ a nnukwu oxidation emee. Aluminom nitride kwụsiri ike na ikuku hydrogen na carbon dioxide ruo 980 Celsius.
Ihe na-agbaze nwayọọ nwayọọ na ịnweta acids site na mbuso agha nke oke ọka, yana na alkalis siri ike site na mbuso agha na aluminom nitride grains. Ihe hydrolyzes ji nwayọọ nwayọọ na mmiri. Ọtụtụ ngwa ugbu a dị na mpaghara eletrọnịkị ebe iwepụ okpomọkụ dị mkpa. Ihe a na-adọrọ mmasị dị ka ihe ọzọ na-adịghị egbu egbu na beryllia. Ụzọ nhazi ígwè dị maka ikwe ka AlN jiri ya mee ihe n'ọnọdụ alumina na BeO maka ọtụtụ ngwa eletrọnịkị
