Al2O3 nanopowders spherical alpha Alumina ya silikoni yotentha yochititsa chidwi

Chifukwa cha kukhuthala kwake kwabwino, kusinthasintha, ntchito yabwino yoponderezedwa komanso kutenthetsa bwino kwa matenthedwe, gel osakaniza silika nthawi zambiri amagwiritsidwa ntchito ngati chodzaza kutentha kwa IC gawo la zida zamagetsi monga zida zolumikizirana ndi makompyuta.Common inorganic non-metallic thermally conductive insulating zodzaza ufa zikuphatikizapo aluminium nitride, aluminium oxide, zinc oxide, beryllium oxide, silicon oxide, silicon carbide, boron nitride, etc. ndi 30W/m·K), ndipo yakhala ikugwiritsidwa ntchito kwambiri m’zinthu zotchinjiriza m’munda wamagetsi okwera kwambiri ndi zida zosinthira za UHV.

Alumina particles okhala ndi matenthedwe apamwamba kwambiri ayenera kukhala ndi digiri yapamwamba ya crystallinity ndi compactness.Alpha-phase alumina ali ndi mawonekedwe a hexagonal, omwe ndi olimba kwambiri pakati pa mitundu yosiyanasiyana ya aluminiyamu.Kafukufuku wasonyeza kuti gawo la alpha la ufa wa alumina, makhiristo ndi makhiristo amodzi ndi tinthu tating'onoting'ono, ndipo pali ndege zina zamakristali.Mukadzazidwa mu silika gel osakaniza, wina mzere kukhudzana ndi pamwamba adzaoneka pamene particles kukhudzana ndi particles.Kulumikizana, kotero matenthedwe madutsidwe a silika gel osakaniza akhoza kwambiri bwino.
