Tlhaloso ea Sehlahisoa
Aluminium Nitride, formula AlN, ke thepa e ncha ho lelapa la lisebelisoa tsa ceramic. Le hoja ho sibolloa ha eona ho etsahetse lilemong tse fetang 100 tse fetileng, e 'nile ea ntlafatsoa ho ba sehlahisoa se ka sebelisoang khoebong se nang le thepa e laoloang le e ka ikatisang nakong ea lilemo tse 20 tse fetileng.
Aluminium nitride e na le sebopeho sa kristale sa hexagonal mme ke thepa e kopantsoeng e kopaneng. Tšebeliso ea lithuso tsa sintering le ho tobetsa ho chesang hoa hlokahala ho hlahisa thepa e teteaneng ea boemo ba tekheniki. Lintho tse bonahalang li tsitsitse ho ea mocheso o phahameng haholo moeeng oa inert. Moeeng, oxidation ea bokaholimo e qala ka holimo ho 700°C. Lera la mofuta oa aluminium oxide le sireletsang thepa ho fihlela ho 1370 ° C. Ka holim'a mocheso ona ho etsahala oxidation ea bongata. Aluminium nitride e tsitsitse moeeng oa hydrogen le carbon dioxide ho fihlela ho 980°C.
Thepa e qhibiliha butle-butle ka li-mineral acids ka tlhaselo ea moeli oa lijo-thollo, le ka li-alkali tse matla ka tlhaselo ea lithollo tsa aluminium nitride. Lintho tse entsoeng ka hydrolyzes butle-butle ka metsing. Lisebelisoa tse ngata tsa morao-rao li sebakeng sa elektronike moo ho tlosoa ha mocheso ho leng bohlokoa. Sesebediswa sena se khahla joalo ka mofuta o seng chefo ho feta beryllia. Mekhoa ea tšepe e teng ho lumella AlN hore e sebelisoe sebakeng sa alumina le BeO bakeng sa lits'ebetso tse ngata tsa elektroniki
Lintho Tsa 'Mele
✔ Lintho tse ntle tsa dielectric
✔ Boima bo phahameng ba mocheso
✔ Coefficient e tlase ea katoloso ea mocheso, e haufi le ea Silicon
✔ E sa sebetseng ka lik'hemik'hale le likhase tse tloaelehileng tsa semiconductor
Lisebelisoa
✔ Lichelete tsa mocheso le li-spreaders tsa mocheso
✔ Li-insulator tsa motlakase bakeng sa lasers
✔ Li-Chucks, mehele ea clamp bakeng sa lisebelisoa tsa ho lokisa semiconductor
✔ Li-insulator tsa motlakase
✔ Ho sebetsana le ho sebetsa ha silicon wafer
✔ Li-substrates le li-insulators tsa lisebelisoa tsa microelectronic le lisebelisoa tsa elektroniki tsa opto
✔ Substrates bakeng sa liphutheloana tsa elektroniki
✔ Bajari ba chip bakeng sa li-sensor le li-detectors
✔ Li-chiplets
✔ Li-Collets
✔ Likarolo tsa tsamaiso ea mocheso oa laser
✔ Lisebelisoa tsa tšepe tse qhibilihisitsoeng
✔ Liphutheloana tsa lisebelisoa tsa microwave
