Kev txhim kho tam sim no ntawm cov hlau silicon
Nrog kev txhim kho txuas ntxiv ntawm cov ntaub ntawv thev naus laus zis thoob ntiaj teb, kev xav tau thoob ntiaj teb rau silicon matal tau loj hlob sai, feem ntau yog siv los ua cov khoom siv hluav taws xob, cov hnub ci, ntau yam kev sib txuas ua ke, cov hlau hlau, riam phom tub rog, kev sib txuas lus fiber ntau, ua tau zoo ntawm silicon organic compounds thiab lwm yam siv dav hauv aerospace, hluav taws xob thiab hluav taws xob, kev tsim kho, kev thauj mus los, tshuaj lom neeg, textile, zaub mov, kev lag luam teeb, kev kho mob, kev ua liaj ua teb thiab lwm yam lag luam. Tshwj xeeb tshaj yog nyob rau xyoo tas los no, nrog kev txhim kho nrawm ntawm hnub ci photovoltaic, tsheb, kev tsim kho vaj tsev, xov xwm hluav taws xob ntau lub lag luam, tab sis kuj ua rau cov khoom siv silicon tau ntsib kev hloov pauv loj los ntawm kev xa khoom mus rau ntau dhau.
Txij li xyoo 2011, PV kev ua lag luam tau txuas ntxiv nyob rau hauv doldrums, kev lag luam ntawm kev tsim cov teb chaws tau ntsib teeb meem kev txhim kho cua sov, kev lag luam ntawm cov teb chaws tau tsim tau rov qab qeeb, cov teeb meem European nuj nqis tseem tsis tau raug tshem tawm, thiab kev loj hlob tag nrho ntawm kev lag luam thoob ntiaj teb tau qeeb. Raws li lub Rau Hli 2013, kev tsim cov hlau silicon hlau thoob ntiaj teb hauv thawj ib nrab ntawm 2013 yog 4.94 lab tonnes, nce 3.1% xyoo-rau-lub xyoo, thiab kev tsim cov hlau silicon hlau thoob ntiaj teb hauv thawj ib nrab ntawm 2013 yog 1.09 lab tonnes, nce 6.8% xyoo -nyob rau xyoo. Ntawm cov no, Kev lag luam sab hnub poob tau ruaj khov, nrog cov khoom siv hlau ua los ntawm cov khoom siv tsis hloov pauv ntau. Muaj 13 lub tuam txhab loj tshaj plaws txawv teb chaws silicon hlau, loj tshaj plaws uas tsis yog Spanish Atlantic Ferroalloys Group, uas tau tsim 101,000 tons hauv thawj ib nrab xyoo 2013 (tsis suav nrog Suav cov nroj tsuag), poob 2.8% xyoo-rau-xyoo. Thoob Ntiaj Teb Metallurgy hauv Tebchaws Meskas yog lub tuam txhab loj tshaj plaws thib ob txawv teb chaws silicon hlau, nrog rau tag nrho cov khoom lag luam silicon tau nce mus rau 96,000 tonnes, txawm tias qhov tseeb tias Kev Lag Luam Thoob Ntiaj Teb Metallurgy tau tshaj tawm poob hauv ob lub hlis thib ob thiab thib peb ntawm 2013. Brazil yog cov neeg tsim khoom loj tshaj plaws ntawm silicon hlau sab nrauv ntawm Tuam Tshoj thiab xa tawm feem ntau ntawm nws cov khoom mus rau Tebchaws Europe thiab Asmeskas Hauv thawj ib nrab ntawm 2013, Brazilian silicon hlau ntau lawm tau poob vim qhov txuas ntxiv tus nqi qis ntawm cov hlau silicon hauv Asmeskas Txawm li cas los xij, qhov cuam tshuam tag nrho ntawm kev ua lag luam tau txwv tsis pub tshaj vim qhov kev hloov pauv me me thiab kev tsim khoom tau cia siab tias yuav loj hlob ntxiv hauv ib nrab xyoo thib ob ntawm lub xyoo. Russia, Australia, Iran thiab lwm lub tebchaws, vim lawv lub hauv paus tsim khoom me me, kev ua lag luam ruaj khov, muaj hnub nyoog nyob ze rau lub xeev tsim khoom tag nrho, kev hloov pauv tau txwv ntau heev.
Yog li, nws pom tias qhov nce hauv cov khoom siv silicon hlau hauv Suav teb tau coj mus rau kev tsim khoom hauv ntiaj teb. Txawm li cas los xij, kev nce ntxiv hauv ntiaj teb cov khoom siv silicon hlau tseem pom kev poob qis. Nyob rau thawj ib nrab ntawm 2013, kev siv silicon hlau thoob ntiaj teb tag nrho 1.07 lab tonnes, nce 3.9% xyoo-rau-xyoo los ntawm 2012: ntawm uas 490,000 tons ntawm aluminium alloys tau siv, nce 8.6% xyoo-rau-xyoo; 420,000 tonnes ntawm cov organic silicon tau siv, nce 5.2% xyoo-rau-xyoo; thiab 120,000 tons ntawm polysilicon tau siv, poob 20% xyoo-rau-lub xyoo.
