(Atolankhani otentha sinteredAlNopangidwa ndiWintrustek）

Hot press sintering ndi ntchito yothira ceramic mopanikizika kwambiri. Zimalola kutenthetsa nthawi imodzi ndi kupangidwa mwamphamvu kwa zoumba kuti apange zinthu zokhala ndi njere zabwino, zochulukirachulukira kwambiri, komanso makina amphamvu.

Kukanikiza kotentha ndi koyenera kwambiri popanga zitsulo zotentha kwambiri (UHTCs), zomwe ndi zinthu zomwe sizimatenthedwa kwambiri ndi kutentha kwambiri pakapangidwe ka sintering.

Kwa zaka zambiri, ofufuza ayesa njira zingapo zopangira sinteringAlNndi kuwonjezera mawonekedwe ake.AlNimawonetsa kulumikizana kogwirizana, chifukwa chake, kuti mupeze kachulukidwe kokwanira, iyenera kutenthedwa pa kutentha kopitilira 1800 ℃. Hot kukanikiza Choncho ntchito makampani kuti sinterAlNpopanda zowonjezera za sintering.

Hot-press sintering ndi njira yomwe imagwiritsidwa ntchito nthawi zambiri powonjezera mphamvu zama ceramics a AlN chifukwa cha izi. Choyamba, kachulukidwe kothandizidwa ndi kukakamiza kumachitika molumikizana ndi makina osindikizira otentha kuti athandizire kupanga zida zadothi za AlN. Kuthamanga kwakunja kumapangitsa kuti kachulukidwe mphamvu yowonjezereka yokankhira poyerekeza ndi sintering yopanda pake, kutsitsa kutentha kwa sintering pafupifupi 50-150 ℃ ndikuchepetsa kumera kwa mbewu zazikulu.

Aluminiyamu ya nitride ceramic yoponderezedwa ndi Hot-pressed ikugwiritsidwa ntchito mumsika wa semiconductor yomwe imafunika kulimba kwamagetsi, kulimba kwamphamvu kwambiri komanso kutenthetsa bwino kwambiri.
