Dab tsi yog alumina cov pob

Alumina pob kuj tseem hu ua spherical alumina. Nws yog cov khoom ua haujlwm tau npaj tau los ntawm high- kub yaj cov txheej txheem rau roj hmab, yas, thiab cov organic silicon khoom. Nws cov ntsiab lus zoo nyob rau hauv cov ntsiab lus siab ntawm alpha theem alumina (ntau dua lossis sib npaug zos, siab thermal conductivity, thiab cov coj tsis kam tiv taus.
Vim nws lub siab sphericity thiab tswj particle loj muab faib tawm high- qhov sib xyaw ua ke sau (nce txog 87%) hauv cov organic sivicon systems, sib xyaw ua viscosity tsawg. Nws yog qhov haum rau thermal interface cov ntaub ntawv, thermal engineering plastics, thiab txhuas los tooj liab- yaj laminates. Lub siab thermal conductivity ua nws cov khoom puv tau ua kom muaj zog zoo dua li crystalline recicon hmoov, thaum lub txheej txheem sib tov txo cov khoom hnav sib tov. Nyob rau hauv lub siab - alpha ci khoom lag luam tiv thaiv shoanium / tsawg dua los yog sib npaug rau kev siv lub zog hluav taws xob thiab HBM ntim. Ntau tshaj 50% ntawm lub ntiaj teb kev ua lag luam cov hmoov cua sov yog cov tshuaj alumina, nrog rau kev nce qib tseem ceeb rau peb lub zog hluav taws xob tshiab.
Lub ntsiab nta ntawm alumina npas
1. Kev sau cov hluav taws xob siab heev: nrog nws cov kab ke loj loj thiab tsim kom muaj cov roj hmab thiab tsim kom muaj viscosity thiab zoo.
2. Muaj siab thermal conductivity: kev sib sau ua ke ua ke nrog cov sib txuas ua ke nrog cov hluav taws xob thermal thiab ntau dua kub ua si tus nqi piv rau cov crystalline silica.
3. Tsawg abrasivity: vim nws kheej kheej kheej, tsawg - kev coj ntawm kneading machine, kev sib sau ua machine thiab tuag.
Lub hom phiaj ntawm alumina npas
(1) Cov dab cua sov, muab tub lim rau cov cua sov disstrate (mc substrate), sov dissipation roj, theem hloov zaj duab xis
(2) Muab tub lim rau slicationconductor ntim khoom
(3) organic silicon sov disspation nplaum thiab filler rau kev sib xyaw
(4) Lim Lim Ceramic
