Al2O3 nanopowders spherical alpha Alumina rau thermal conductive silicone

Vim nws cov viscosity zoo, yooj, compression kev ua tau zoo thiab zoo thermal conductivity, thermally conductive silica gel feem ntau yog siv los ua cua sov dissipation muab tub lim rau IC substrates ntawm cov khoom siv hluav taws xob xws li cov khoom siv sib txuas lus thiab cov computers.Common inorganic non-metallic thermally conductive insulating. Cov hmoov nplej muaj xws li txhuas nitride, aluminium oxide, zinc oxide, beryllium oxide, silicon oxide, silicon carbide, boron nitride, thiab lwm yam. Ntawm lawv, alumina tsis tsuas yog muaj cov khoom zoo rwb thaiv tsev, tab sis kuj nws cov thermal conductivity tsis tsawg (ib txwm kub thermal conductivity. yog 30W / m·K), thiab nws tau siv dav hauv cov khoom siv rwb thaiv tsev hauv kev siv hluav taws xob siab thiab UHV hloov khoom siv.

Alumina hais nrog siab thermal conductivity yuav tsum lawv tus kheej muaj qib siab ntawm crystallinity thiab compactness.Alpha-phase alumina muaj cov qauv hexagonal, uas yog cov qauv ntom ntom ntawm ntau yam alumina variants.Cov kev tshawb fawb pom tau hais tias qhov siab dua alpha theem ntawm alumina hmoov, cov muaju yog ib qho crystals tag nrho thiab kheej kheej, thiab muaj qee yam siv lead ua dav hlau.Thaum sau rau hauv silica gel, qee txoj kab sib cuag thiab qhov chaw yuav tshwm sim thaum cov khoom sib cuag nrog cov khoom.Kev sib cuag, yog li cov thermal conductivity ntawm silica gel tuaj yeem txhim kho tau zoo.
