Al2O3 nanopowders spherical alpha Alumina ye thermal conductive silicone

Nekuda kwekunaka kwayo kupenya, kuchinjika, kuita kwakanaka kwekumanikidza uye yakanakisa kupisa kwemafuta, thermally conductive silica gel inowanzoshandiswa seyekupisa inobvisa kupisa kweiyo IC substrates yemidziyo yemagetsi yakadai semidziyo yekutaurirana nemakomputa.Common inorganic non-metallic thermally conductive insulating. poda fillers inosanganisira aluminium nitride, aluminium oxide, zinc oxide, beryllium oxide, silicon. oxide, silicon carbide, boron nitride, etc.Pakati pazvo, alumina haina kungoita zvakanaka kuvharidzira zvinhu, asiwo iyo inopisa conductivity haina kuderera (yakajairika tembiricha thermal conductivity ndeye 30W/m·K), uye yakashandiswa zvakanyanya mukudzivirira. zvigadzirwa mumunda weyakakwira voltage uye UHV switch midziyo.

Alumina particles ane high thermal conductivity anofanirwa ivo pachavo kuve nehupamhi hwekristaro uye compactness. Alpha-phase alumina ine hexagonal chimiro, chinova chakaomesesa chimiro pakati peakasiyana alumina akasiyana. Zvidzidzo zvakaratidza kuti iyo yakakwira alpha chikamu chealumina poda, makristasi akazara makristasi ega uye spherical particles, uye kune dzimwe ndege dzekristaro. Kana yazadzwa musilica gel, imwe mutsara yekubata uye pamusoro ichaonekwa kana zvimedu zvasangana nezvimedu. Kubata, saka iyo yekupisa conductivity yesilica gel inogona kuvandudzwa zvakanyanya.
