Al2O3 nanopowders spherical alpha Alumina mo silicone conductive thermal

Ona o lona viscosity lelei, fetuutuunai, lelei compression faatinoga ma le lelei tele conductivity vevela, thermally conductive silica gel e masani ona faʻaaogaina e avea o se faʻamaʻi vevela faʻatumu mo le IC substrates o mea eletise e pei o meafaigaluega fesoʻotaʻiga ma komepiuta. Common inorganic non-metallic thermally conductive insulating faʻatumu paʻu e aofia ai le nitride alumini, alumini oxide, zinc oxide, beryllium oxide, silicon oxide, silicon carbide, boron nitride, ma isi.I totonu ia i latou, o le alumina e le gata o loʻo i ai ni mea faʻapipiʻi lelei, ae e le o maualalo foʻi lona faʻauluina vevela. o le 30W/m·K), ma ua fa'aaogaina lautele i oloa fa'alumaina i le fanua o eletise maualuga ma mea fa'aoga UHV.

O vaega alumina e maualuga le vevela e tatau ona i ai se maualuga maualuga o le tioata ma le faʻapipiʻi.Alpha-phase alumina o loʻo i ai se fausaga hexagonal, o le fausaga sili ona mafiafia i le eseesega o alumina eseese.O suʻesuʻega ua faʻaalia ai o le maualuga o le alpha alpha o le alumina paʻu, o tioata o tioata taʻitoʻatasi atoa ma vaega faʻapitoa, ma o loʻo i ai ni vaalele tioata.A faʻatumu i le silica gel, o se laina faʻafesoʻotaʻi ma luga o le a aliali mai pe a faʻafesoʻotaʻi vaega ma vaega.Faʻafesoʻotaʻi, ina ia mafai ona faʻaleleia atili le faʻafefe o le silica gel.
