Okwu mmalite nke aluminom nitride

Aluminom nitride (AlN) bụ ihe na-acha ọcha ma ọ bụ isi awọ nonmetallic nwere ihe dị arọ nke 40.98, ebe agbaze nke 2200 ℃, ebe esi esi 2510 ℃, yana njupụta nke 3.26g/cm³.Aluminom nitride bụ ihe ọhụrụ seramiiki nke nwere ihe nrụpụta ọkụ dị elu, oke ọkụ na-eguzogide, nnukwu nguzogide corrosion, mkpuchi dị elu na nguzogide dị mma, nke a na-ejikarị eme ihe na ngwá electronic, ọkụ eletrik, ikuku ikuku, ngwá ọrụ ziri ezi na mpaghara ndị ọzọ.

Njirimara nke aluminom nitride

1. Thermal Njirimara:aluminom nitride nwere nnukwu ikuku thermal conductivity, nke abụọ naanị diamond, enwere ike iji ya ogologo oge na oke okpomọkụ.

2. Mechanical Njirimara:aluminom nitride nwere nnukwu ike ike na ezigbo mgbochi iyi.

3. Ngwa eletriki: aluminum nitride nwere ezigbo mkpuchi ọkụ.

4. Ngwa anya:Aluminom nitride nwere ezigbo ngwa anya, yana oke nnyefe ọkụ ya bụ 200-2000nm, yana nnyefe karịa 95%.

Usoro nkwadebe nke aluminom nitride

Usoro nkwadebe aluminom nitride bụ nke kachasị dị ka ndị a:

1. Usoro mbelata nke ikuku carbon:A na-agwakọta calcium carbonate na alumina na carbon ntụ ntụ, na-ekpo ọkụ ruo 1500-1600 ℃ n'ime ọkụ ọkụ, nke mere na carbon na-emeghachi omume na oxygen iji mepụta carbon dioxide, carbon fọdụrụnụ na-emeghachi omume na calcium carbonate iji mepụta calcium na carbon dioxide, ma mesịa nweta aluminum. nitride.

2. Usoro nitriding ozugbo:Gwakọta alumina ma ọ bụ nnu aluminom na amonia, tinye ego kwesịrị ekwesị nke ammonium chloride iji dozie uru pH, nweta mgbagwoju anya nke ion na amonia ion, wee kpoo ọkụ na elu okpomọkụ ruo 1000-1200 ℃, nke mere na amonia decomposition n'ime amonia gas. , na n'ikpeazụ nweta aluminum nitride.

3. Usoro ịgbasa:na elu ume ion beam sputtering aluminum tetrachloride na nitrogen, aluminum tetrachloride meghachi omume na nitrogen na-emepụta aluminum nitride na elu okpomọkụ, mgbe na-anakọta aluminom nitride ntụ ntụ.

Ojiji nke aluminom nitride

1. Ebe eletrọnịkị:Aluminom nitride, dị ka ihe na-ekpo ọkụ dị elu, na-ejikarị na nkwakọ ngwaahịa eletrọnịkị, dị ka ibe semiconductor, transistor, wdg.

2. Ebe ike:Igwe ọkụ dị elu na nguzogide corrosion nke aluminom nitride na-eme ka a na-eji ya eme ihe na usoro ike, dị ka ihe ntụgharị, capacitors na ihe ndị ọzọ.

3. Oghere ikuku:Ike dị elu nke aluminom nitride, ike siri ike na nguzogide dị mma na-eme ka a na-eji ya eme ihe na mbara ikuku, dị ka igwe ụgbọ elu, satịlaịtị na ihe ndị ọzọ.

4. Ogige ngwá ọrụ nkenke:nnyefe ọkụ dị elu na ọmarịcha ngwa anya nke aluminom nitride na-eme ka a na-ejikarị ya eme ihe n'ọhịa nke ngwa ngwa, dị ka anya anya anya, prisms, wdg.

Atụmanya mmepe nke aluminom nitride

Site na mmepe sayensị na teknụzụ na-aga n'ihu, aluminom nitride dị ka ụdị ihe ọhụrụ seramiiki, mpaghara ngwa ya na-aga n'ihu na-abawanye, ahịa ahịa na-abawanye.N'ọdịnihu, na-aga n'ihu na-emeziwanye usoro nkwadebe nke aluminum nitride na mbelata ọnụ ahịa, a ga-etinye nitride aluminom na mpaghara ndị ọzọ.
