Vim li cas Silicon Hlau Nqe Tsiv
Silicon hlau yog cov khoom siv tseem ceeb rau hnub ci hlwb, semiconductors, silicones, aluminium alloys thiab tshwj xeeb steels. Nws tus nqi yog teem los ntawm kev sib cuam tshuam ntawm ib tug me me ntawm cov qauv quab yuam: qhov kev thov rau polysilicon, lub zog nqi ntawm smelting, lub geographic concentration ntawm ntau lawm, thiab theem ntawm downstream muaj kev ua si. Thaum ob peb lub zog no txav mus rau tib qho kev taw qhia, cov nqi tuaj yeem nce siab hauv lub qhov rai luv. Kab lus no rhuav tshem txhua tus neeg tsav tsheb thiab yuav ua li cas nws pab txhawb kev nce siab ntawm cov nqi hlau silicon.
Demand Driver: Polysilicon thiab Hnub Ci Zog
Qhov ceev tshaj plaws - loj hlob qhov kev thov rau silicon hlau yog polysilicon, purified daim ntawv ntawm silicon siv nyob rau hauv photovoltaic hlwb. Hnub ci module tsim tau nthuav dav thoob plaws ntiaj teb, thiab txhua qhov tshiab polysilicon cog yuav tsum muaj ntau yam ntawm metallurgical- qib silicon li pub. Vim tias muaj peev xwm polysilicon ntxiv rau hauv cov kauj ruam loj, qhov ramp - nce ntawm cov nroj tsuag tshiab tuaj yeem tsim kev dhia sai sai hauv silicon hlau xav tau. Thaum lub hnub ci kev teeb tsa lub hom phiaj nce siab, cov nyhuv mus sai sai rau cov khoom siv, thiab cov nqi silicon hlau teb nyob rau tib lub hlis twg hauv ntau qhov xwm txheej.
Lub zog siv zog: Smelting tshaj 1,800 Degrees Celsius
Silicon hlau yog tsim los ntawm carbothermic txo ntawm quartz nyob rau hauv submerged hluav taws xob -arc furnaces ntawm kub siab tshaj 1,800 degrees Celsius. Cov txheej txheem siv hluav taws xob ntau heev, thiab lub zog yog ib qho ntawm cov khoom loj tshaj plaws ntawm cov nqi tsim khoom. Cov nqi hluav taws xob yog li tus nqi ncaj qha: thaum hluav taws xob pheej yig dua, cov neeg tsim khoom yuav tsum nce nqi lossis txiav tawm, thiab ob qho tib si cov lus teb nruj me ntsis. Txoj cai tswj hwm lub zog, kev txwv kab sib chaws thiab cov nqi hluav taws xob raws caij nyoog hauv cov cheeb tsam tsim tau txhua tus tuaj yeem txhais ua silicon hlau nqi txav.
Geographic Concentration ntawm ntau lawm
Silicon hlau ntau lawm yog concentrated nyob rau hauv ib tug me me ntawm lub teb chaws, nrog Tuam Tshoj yog tus loj tshaj plaws tsim thiab Norway thiab Brazil kuj tuav lub peev xwm tseem ceeb. Concentration txhais tau hais tias kev xa khoom raug cuam tshuam rau hauv cheeb tsam kev poob siab: hluav taws xob tsis txaus, kev tshuaj xyuas ib puag ncig, kev cuam tshuam kev thauj mus los lossis kev hloov txoj cai hauv cheeb tsam tsim khoom tseem ceeb tuaj yeem tshem tawm cov khoom lag luam sai sai. Vim tias muaj ob peb lwm qhov chaw uas tuaj yeem nce siab hauv lub sijhawm luv luv, tus nqi cuam tshuam rau txhua qhov kev cuam tshuam ntau lawm hauv cheeb tsam loj.
Secondary Demand thiab Yuav Ua Li Cas Cov Tsav Tsheb Sib Tham
Tshaj li hnub ci, silicon hlau muaj qhov xav tau kev lag luam ruaj khov. Aluminium alloy producers ntxiv silicon los txhim kho lub fluidity thiab mechanical zog ntawm cam khwb cia txhuas alloys, thiab qhov kev noj no yog nyob ze rau automotive thiab kev tsim khoom. Kev lag luam tshuaj siv silicon hlau ua pub rau silicones thiab silanes. Qhov kev thov hauv qab no tsis hloov pauv raws li qhov xav tau ntawm hnub ci, tab sis nws teeb tsa hauv pem teb hauv qab kev ua lag luam thiab ua qhov tseem ceeb thaum lub hnub ci xav tau muaj zog tib lub sijhawm.
| Tus nqi tsav tsheb | Kev taw qhia ntawm cov nyhuv | Lub Sijhawm kis tau tus mob |
|---|---|---|
| Polysilicon muaj peev xwm expansion | Kev thov siab dua | Quarters |
| Hluav taws xob nqi nce | Tus nqi siab dua, kev muab khoom nruj dua | Lub lis piam mus rau hli |
| Kev cuam tshuam ntau lawm hauv cheeb tsam loj | Muab kev poob siab | Tam sim ntawd mus rau lub lis piam |
| Aluminium alloy thiab tshuaj thov | Kev txhawb nqa hauv paus | Lub hli |
Cov neeg tsav tsheb tsis tshua txav ib leeg. Ib qho kev sib tw nqi pib nrog lub teeb liab thov los ntawm lub hnub ci saw, yog nthuav tawm los ntawm lub zog nqi siab hauv cov cheeb tsam tsim, thiab tuaj yeem ua kom pom tseeb los ntawm kev cuam tshuam cov khoom siv. Cov neeg yuav khoom yuav tsum saib peb qhov ntsuas: polysilicon cog cov nqi khiav lag luam thiab kev nthuav dav, kev tshaj tawm cov nqi hluav taws xob hauv thaj chaw tsim khoom loj, thiab cov khoom lag luam qib ntawm silicon hlau tsim thiab cov chaw nres nkoj. Tus nqi theem hauv kev ua lag luam tau hais ib tuj hauv kev lag luam hauv Suav teb thiab ib kilogram lossis ib tuj hauv kev lag luam thoob ntiaj teb, thiab lawv txav mus ua ke los ntawm arbitrage.
