Gabatarwa zuwa aluminum nitride

Aluminum nitride (AlN) wani fili ne na fari ko launin toka wanda ba shi da ƙarfe mai nauyin kwayoyin halitta na 40.98, wurin narkewa na 2200 ℃, wurin tafasa na 2510 ℃, da yawa na 3.26g/cm³.Aluminum nitride sabon abu ne na yumbu tare da haɓakar zafin jiki mai ƙarfi, juriya mai zafi mai ƙarfi, juriya mai ƙarfi, babban rufi da ingantaccen juriya, wanda ake amfani da shi sosai a cikin kayan lantarki, wutar lantarki, sararin samaniya, daidaitattun kayan aikin da sauran filayen.

Properties na aluminum nitride

1. Thermal Properties:Aluminum nitride yana da babban ƙarfin zafin jiki, na biyu kawai zuwa lu'u-lu'u, kuma ana iya amfani da shi na dogon lokaci a yanayin zafi.

2. Kayayyakin injina:aluminum nitride yana da babban taurin kuma mai kyau juriya.

3. Kayan Wutar Lantarki: aluminum nitride yana da ingantaccen rufin lantarki.

4. Kayayyakin gani:Aluminum nitride yana da kyawawan kaddarorin gani, kuma kewayon watsa haskensa shine 200-2000nm, tare da watsawa fiye da 95%.

Hanyar shiri na aluminum nitride

Hanyoyin shirye-shiryen Aluminum nitride sun fi kamar haka:

1. Hanyar rage sinadarin Carbothermal:Calcium carbonate da alumina ana haxa su da carbon foda, ana mai zafi zuwa 1500-1600 ℃ a cikin tanderun fashewa, ta yadda carbon ke amsawa da iskar oxygen don samar da carbon dioxide, sauran carbon yana amsawa da calcium carbonate don samar da calcium da carbon dioxide, kuma a ƙarshe ya sami aluminum. nitride.

2. Hanyar nitriding kai tsaye:Mix alumina ko aluminum gishiri tare da ammonia, ƙara daidai adadin ammonium chloride don daidaita pH darajar, samun hadaddun na aluminum ion da ammonia ion, sa'an nan zafi a high zafin jiki zuwa 1000-1200 ℃, sabõda haka, ammonia bazuwa cikin ammonia gas. , kuma a ƙarshe sami aluminum nitride.

3.Hanyar watsawa:tare da babban makamashi ion katako sputtering aluminum tetrachloride da nitrogen, aluminum tetrachloride reacts tare da nitrogen don samar da aluminum nitride a high zafin jiki, yayin da tattara da generated aluminum nitride foda.

Amfani da aluminum nitride

1. Filin lantarki:Aluminum nitride, a matsayin babban abu mai ɗaukar zafi, ana amfani dashi ko'ina a cikin marufi na na'urorin lantarki, irin su guntuwar semiconductor, transistor, da sauransu.

2. Filin wutar lantarki:Babban juriya na zafi da juriya na aluminium nitride ya sa ana amfani da shi sosai a cikin tsarin wutar lantarki, kamar su masu canza wuta, capacitors da sauransu.

3. Filin sararin samaniya:Ƙarfin aluminum nitride, ƙarfin ƙarfi mai ƙarfi da kyakkyawan juriya mai raɗaɗi ya sa ana amfani da shi sosai a filin sararin samaniya, kamar injin jirgin sama, tauraron dan adam da sauransu.

4. Madaidaicin filin kayan aiki:Babban watsa haske da kyawawan kaddarorin gani na aluminium nitride sun sanya shi amfani da shi sosai a fagen kayan aikin daidai, kamar ruwan tabarau na gani, prisms, da sauransu.

Hasashen haɓaka na aluminium nitride

Tare da ci gaba da ci gaban kimiyya da fasaha, aluminum nitride a matsayin sabon nau'in kayan yumbu, filin aikace-aikacensa yana ci gaba da fadadawa, buƙatar kasuwa kuma yana karuwa.A nan gaba, tare da ci gaba da inganta tsarin shirye-shiryen nitride na aluminum da kuma rage farashin, za a yi amfani da nitride na aluminum a wasu wurare.
