Dab tsi yog Metallic Silicon?
ZhenAn Hlau Silicon Manufacturers ib puag ncig
Nws yog xim hlau siliconyog ib qho tseem ceeb ntawm cov khoom siv tshuaj lom neeg uas tau siv dav hauv ntau lub lag luam vim nws cov khoom zoo heev thiab tshwj xeeb. Nws yog ib qho nyuaj, nkig, crystalline khoom nrog ib qho ntxim nyiam xiav-grey metallic luster.
Uas feem ntau ntawm silicon, nrog cov cim ntawm lwm yam xws li hlau, txhuas thiab calcium, nws yog qhov xav tsis thoob ntawm xwm.
Nws txoj kev tsim khoom nyuaj suav nrog txo cov silica, ib qho chaw muaj nyob hauv quartz, nrog cov pa roj carbon nyob rau hauv qhov cub kub. Lub resulting metallic silicon yog kwv yees li 98-99% ntshiab.
Txhais thiab muaj pes tsawg leeg ntawm Hlau Silicon
Nws yog ib qho tshuaj lom neeg nrog lub cim Si thiab atomic naj npawb 14. Nws yog ib qho metalloid nrog ob qho tib si hlau thiab cov khoom tsis yog xim hlau, ua rau nws zoo nkauj heev.
Nyob zoo cov neeg nyeem, cov khoom siv ntawm silicon hlau feem ntau yog silicon, uas ua rau lub hauv paus ntawm nws cov qauv. Txawm li cas los xij, nyob ntawm cov txheej txheem ntau lawm, nws kuj tseem tuaj yeem muaj cov khoom tsis huv xws li hlau, txhuas, calcium thiab lwm yam.
Lub purity ntawm cov khoom txawv txawv no yog qhov tseem ceeb rau nws cov kev siv ntau hauv ntau qhov kev lag luam.
Lub cev thiab tshuaj lom neeg cov khoom ntawm hlau silicon
Tam sim no, cia peb delve rau hauv lub cev thiab tshuaj lom neeg muaj zog ntawm silicon hlau uas ua rau nws muaj txiaj ntsig zoo hauv ntau daim ntawv thov. Nws muaj tag nrho hardness thiab brittleness, raws li zoo raws li ib tug txaus nyiam xim hlau tsos.
Nco ntsoov tias cov hlau silicon muaj qhov kub siab heev ntawm qhov kub ntawm 1,414 degrees Celsius thiab kub kub ntawm 3,265 degrees Celsius. Tsis tas li ntawd, nws muaj kev qhuas txog hluav taws xob thiab thermal conductivity, nrog rau cov thermal expansion thiab thermal stability zoo heev. Chemically, silicon hlau zoo li yuav inert, txawm hais tias nws yuav hnov mob nrog tej yam khoom, xws li oxygen, tsim silica nyob rau hauv tej yam kev mob.
