Aluminium nitride (AIN) e tumme ka ho sebetsa ha eona hantle ha mocheso le litšoaneleho tse ikhethang tsa insulating ea motlakase. Ke ntho e tloaelehileng ea ceramic e sebelisoang mefuteng e mengata ea lisebelisoa tsa motlakase. Aluminium nitride ceramics ha e sebetsane le litšepe tse qhibilihisitsoeng, ho akarelletsa le koporo, lithium, le aluminium, ho phaella ho matla a tsona a ho atolosa mocheso le lintho tse sireletsang motlakase. Aluminium nitrideke lisebelisoa tse molemo lits'ebetsong tse fapaneng tsa indasteri ka lebaka la likarolo tsa eona tsa lik'hemik'hale le tsa 'mele.
Leha ho le joalo, tlhahisong, aluminium nitride e arotsoe ka mefuta e 'meli ho latela ts'ebetso ea sintering: pr.essureless sintered aluminium nitride lealuminium nitride e hatelitsoeng ka mocheso o chesang. Likarolo le ts'ebeliso ea likarolo tsena tse peli li fapana haholo.
Aluminium nitride e se nang khatelloe kopanya phofo e phahameng ea aluminium nitride e nang le thuso e nyenyane ea sintering (e kang Y2O3), ho etsa motsoako ka mokhoa o lakatsehang (mohlala, ka ho hatella ka ho omella kapa ho hatella isostatic), ebe o o tšela ka mocheso o phahameng (1800 ° C ho 2000 ° C) tlas'a moea o sireletsang oa inert (nitrogen). Ts'ebetso ena e itšetlehile ka karabelo pakeng tsa thuso ea sintering le alumina e teng holim'a likaroloana tsa AlN, ho etsa karolo ea mokelikeli e khothalletsang ho hlophisoa bocha le ho teteka ha likaroloana.
