3. Yuav ua li cas Silicon hlau yog tsim

Silicon hlau yog tsim los ntawm acarbothermic txo cov txheej txheemnyob rau hauv hluav taws xob arc rauv.

Cov kauj ruam ua kom yooj yim:

Cov khoom siv raw: High-purity quartz (silica) thiab cov khoom siv carbon (xws li cov thee lossis coke)

Siab - qhov kub thiab txias: Cov sib tov yog rhuab tshaj 2,000 ° C nyob rau hauv ib tug hluav taws xob arc rauv

Kev txo qis: Oxygen raug tshem tawm ntawm silica, tsim cov khoom siv silicon

Ua kom txias thiab ua haujlwm: Lub silicon yog txias, crushed, thiab loj

Lub zog no - cov txheej txheem hnyav piav qhia vim li cas cov khoom siv hlau silicon txuas nrog rau kev muaj hluav taws xob thiab nqi.

4. Kev piav qhia ntawm Silicon Hlau Qib

Silicon hlau yog muab faib ua qib xws li1101, 2202, 3303, thiab 553.
Cov qib notsis txhob hloov cov yam ntxwv ntawm silicon, tab sis txhais cov theem tso cai impurity.

High- qib purity (piv txwv li, 1101): nruj impurity tswj, siab dua sib xws

Qib nrab (piv txwv li, 2202): sib npaug ntawm purity thiab nqi

Cov qib lag luam (piv txwv li, 553): nqi-ntau, siv dav hauv ntim ntau lawm

Qib xaiv nyob ntawm qhov rhiab heev ntawm daim ntawv thov downstream.

5. Kev siv tseem ceeb ntawm Silicon hlau

5.1 Aluminium Alloy Ntau Lawm

Qhov loj tshaj plaws ntawm silicon hlau noj yog nyob rau hauvaluminium alloys.

Silicon:

Txhim kho casting fluidity

Txhim khu lub zog thiab hnav tsis kam

Txo shrinkage thaum lub sij hawm solidification

Aluminium alloys sib txawv yuav tsum tau sib txawv silicon hlau qib nyob ntawm impurity kam rau ua thiab kev ua tau zoo.

5.2 Kev lag luam tshuaj

Silicon hlau yog cov khoom siv tseem ceeb rau kev tsim khoom:

Silicones

Silanes

Lwm yam silicon{0}}raws li tshuaj

Cov ntawv thov no feem ntau xav tausiab dua -purity silicon hlaukom ruaj khov tshuaj tiv thaiv thiab cov khoom zoo.

5.3 Metallurgical Applications

Hauv metallurgy, silicon hlau yog siv raws li:

Ib qho alloying

Ib tug txo tus neeg sawv cev nyob rau hauv tej yam txheej txheem

Nws tus cwj pwm uas xav tau ntawm qhov kub thiab txias ua rau nws muaj txiaj ntsig zoo hauv kev tswj cov tshuab metallurgical.

6. Vim li cas Silicon hlau zoo teeb meem

Txawm hais tias silicon hlau tuaj yeem tshwm sim los ua cov khoom lag luam,qhov zoo sib txawv muaj qhov tshwm sim ntawm kev lag luam tiag.

Cov theem impurity tuaj yeem cuam tshuam:

Alloy sib xws

Mechanical zog

Corrosion kuj

Tshem tawm thiab rov ua haujlwm

Vim li no, cov neeg siv khoom paub txog kev ntsuas silicon hlau sivCOA cov ntaub ntawv, cov khoom sib xws, thiab kev ntseeg siab ntawm tus neeg muag khoom, tsis yog los ntawm qib npe lossis tus nqi.
