Silicon hlau Silicon Powder

Silicon hlau hmoov yog ib daim ntawv zoo hauv av ntawm cov khoom siv silicon uas feem ntau siv rau ntau yam kev lag luam. Nws yog tsim los ntawm kev txo qis ntawm high-purity quartz los yog quartzite nrog carbon nyob rau hauv ib tug hluav taws xob arc rauv. Lub resulting silicon hlau yog ces milled thiab ua tiav rau hauv daim ntawv hmoov.

Silicon hlau hmoov muaj ntau yam khoom uas ua rau nws siv tau rau ntau yam kev siv. Qee yam ntawm cov khoom no muaj xws li:

High thermal conductivity: Silicon hlau hmoov muaj cov thermal conductivity siab, ua rau nws yog ib qho khoom siv zoo tshaj plaws rau kev siv cov khoom siv thermal, xws li cov dab dej kub.

Tsawg coefficient ntawm thermal expansion: Silicon hlau hmoov muaj cov coefficient tsawg ntawm thermal expansion, txhais tau hais tias nws yuav tsis nthuav los yog cog lus loj heev thaum raug hloov nyob rau hauv qhov kub thiab txias.

High melting point: Silicon hlau hmoov muaj qhov siab melting point ntawm ib ncig ntawm 1,410 degree, uas ua rau nws muaj txiaj ntsig zoo hauv cov ntawv thov uas muaj qhov kub thiab txias.

Cov khoom siv hluav taws xob zoo: Silicon hlau hmoov yog cov khoom siv hluav taws xob zoo, ua rau nws muaj txiaj ntsig zoo hauv kev siv hluav taws xob ntau.

High purity: Silicon hlau hmoov tuaj yeem tsim nrog purity siab heev, uas ua rau nws zoo tagnrho rau siv hauv cov khoom siv hluav taws xob uas txawm tias me me impurities tuaj yeem cuam tshuam kev ua haujlwm.
