Kev piav qhia
Hlau silicon hmoov plays lub luag haujlwm tseem ceeb hauv kev tsim khoom ntawm ntau cov khoom lag luam xws li semiconductors, solar panels, thiab refractories. Kev tsim cov khoom siv tseem ceeb no pib nrog kev xaiv cov ntaub ntawv raw. Hauv tsab xov xwm no, peb yuav tshawb xyuas txhua yam koj xav paub txog cov ntaub ntawv raw rau hlau silicon hmoov ntau lawm.
Silicon: Cov Khoom Siv Tseem Ceeb
Cov hmoov hlau silicon feem ntau yog ua los ntawm silicon, uas yog qhov thib ob ntau tshaj plaws nyob rau hauv lub ntiaj teb crust. Kev lag luam, silicon yog muab rho tawm los ntawm silicate minerals xws li quartz thiab feldspar. Cov txheej txheem ntau lawm pib nrog tau txais cov ntshiab silicon, uas yog tom qab ntawd hloov mus rau hauv cov hmoov hlau silicon hmoov.
Carbon: Cov khoom siv thib ob
Cov pa roj carbon monoxide yog cov khoom siv thib ob siv hauv kev tsim cov hlau silicon hmoov. Lub hauv paus ntawm carbon yuav yog coke, thee, lossis charcoal. Carbon yog siv thaum lub sij hawm tsim cov hlau silicon hmoov los txo cov silicate minerals rau hauv silicon ntshiab thiab tshem tawm impurities xws li oxygen thiab sulfur.

Lwm yam Raw Materials
Sib nrug los ntawm silicon thiab carbon, lwm yam khoom siv raw yuav raug ntxiv thaum lub sij hawm tsim cov hlau silicon hmoov. Cov khoom siv raw no suav nrog:
1. Aluminium: Aluminium yog siv los txo qhov melting point ntawm cov hlau silicon hmoov thiab tsim kom muaj ib qho sib tov sib xyaw.
2. Calcium: Calcium ntxiv los tswj tus nqi ntawm cov hlau silicon hmoov reacts nrog oxygen thiab tshem tawm tej impurities xws li txhuas, hlau, thiab titanium.
3. Hlau: Hlau nce qhov ntom, lub zog, thiab hardness ntawm cov hlau silicon hmoov.
Kev siv cov khoom siv rov ua dua tshiab
Recycling plays lub luag haujlwm tseem ceeb hauv kev tsim cov hlau silicon hmoov. Kev rov ua dua tshiab tsis yog tsuas yog pab txo cov khoom pov tseg xwb tab sis kuj txuag lub zog thiab txo cov pa roj carbon dioxide emissions. Cov ntaub ntawv siv dua tshiab xws li silicon seem thiab silicon wafers tuaj yeem siv los ua cov khoom siv raw hauv cov hlau silicon hmoov ntau lawm.
Xaus
Kev tsim cov hlau silicon hmoov yog txheej txheem nyuaj uas yuav tsum tau xaiv cov ntaub ntawv raw. Silicon yog thawj cov khoom siv raw, thaum carbon yog cov khoom siv thib ob uas siv los txo cov pob zeb hauv av rau hauv silicon ntshiab. Lwm cov ntaub ntawv nyoos xws li txhuas, calcium, thiab hlau tuaj yeem ntxiv thaum lub sijhawm tsim khoom. Recycling plays lub luag haujlwm tseem ceeb hauv kev tsim cov hlau silicon hmoov, thiab cov khoom siv rov ua dua tuaj yeem siv los ua cov khoom siv raw. Los ntawm kev xaiv cov ntaub ntawv raw, kev tsim cov hlau silicon hmoov tuaj yeem ua kom zoo kom tau raws li cov kev xav tau tshwj xeeb ntawm ntau daim ntawv thov kev lag luam.
