Cov khoom ntawm kev lag luam silicon zoo ib yam li cov germanium, txhuas, thiab tin, thiab nws cov conductivity yog nruab nrab ntawm cov hlau thiab cov hlau tsis muaj hlau. Yog li ntawd, industrial silicon tseem hu ua silicon hlau. Muaj silicon feem ntau yog tsaus grey nrog xim hlau thiab yog nyob rau hauv daim ntawv ntawm lumps los yog granules. Cov khoom tseem ceeb ntawm cov khoom siv silicon yog cov khoom siv silicon, nrog cov ntsiab lus ntau dua 98.7%. Tsis tas li ntawd, nws muaj me me ntawm hlau, txhuas, calcium thiab lwm yam impurities. Kev lag luam silicon nrog cov khoom sib txawv hauv kev ua lag luam muaj kev siv sib txawv. Yog li ntawd, muaj ob txoj kev faib tawm tseem ceeb rau kev lag luam silicon, ib qho yog los ntawm kev sib xyaw thiab lwm qhov yog los ntawm kev siv.
Raws li cov ntsiab lus silicon thiab cov ntsiab lus impurity tseem ceeb hauv kev lag luam silicon, cov khoom siv silicon tuaj yeem muab faib ua ntau qib. Raws li lub teb chaws tus qauv, kev lag luam silicon tuaj yeem muab faib ua 8 qib. Ntawm lawv, qhov ntau tshaj plaws nyob rau hauv kev ua lag luamSi 553, Si441, Si421, Si411, thiab lwm yam. Si553 tuaj yeem sau ua 553# hauv lub neej txhua hnub. Plaub tus lej kawg ntawm qib sawv cev rau cov khoom tseem ceeb hauv cov khoom. Cov ntsiab lus siab tshaj plaws ntawm impurity ntsiab hlau, txhuas, thiab calcium. Piv txwv li, "4" hauv Si421 txhais tau hais tias cov ntsiab lus hlau hauv kev lag luam silicon tsawg dua 0.4%, "2" txhais tau hais tias cov ntsiab lus txhuas yog tsawg dua 0.2%, thiab " 10" txhais tau tias cov ntsiab lus calcium tsawg dua 0.10%. Noj cov nqi ntawm cov khoom siv silicon nyob rau sab hnub tuaj Suav teb ua piv txwv, tus nqi ntawm 553 # yog qis dua li ntawm 441 # thiab 421 #, thiab tom kawg yog ze rau tus nqi ntawm 3303 #. Raws li lub Tsib Hlis 2022,2202#muaj tus nqi siab tshaj plaws, 12,400 yuan / ton siab dua 3303 #. Impurities tuaj yeem pom Qhov qis dua cov ntsiab lus ntawm kev lag luam silicon, tus nqi siab dua, thiab tus nqi sib txawv ntawm cov khoom siv silicon ntawm cov khoom sib txawv yog loj dua. Tsis tas li ntawd, cov khoom siv silicon tawm sab nraud ntawm lub teb chaws cov qauv tau tshwm sim nyob rau hauv kev ua lag luam, xws li 97 silicon thiab recycled silicon. Cov ntsiab lus ntawm silicon ntawm 97 silicon yog li 98%, thiab nws cov kev siv zoo ib yam li Si553: cov khoom siv silicon yog li 99%, uas tuaj yeem hloov Si441,ib 3303thiab lwm yam kev qhia tshwj xeeb, ob qho tib si tsuas yog suav rau 9.35% ntawm kuv lub teb chaws tag nrho cov khoom siv silicon.
Ntau qib ntawm kev lag luam silicon ntws mus rau ntau qhov chaw, thiab tuaj yeem muab faib ua qib metallurgical thiab qib tshuaj lom neeg. Metallurgical qib kev lag luam silicon feem ntau yog siv los ua aluminium alloys ua ib qho ntxiv kom muaj zog thiab toughness ntawm cov hlau. Cov qib tseem ceeb yog 553#, 551#, 441# thiab 3303#. Ntawm lawv, qhov kev thov rau kev lag luam silicon hauv cam khwb cia aluminium alloys yog siab dua li ntawm deformed aluminium alloys. Aluminium alloy. Cov qib tshuaj muaj cov silicon tuaj yeem siv los tsim cov organic silicon thiab polycrystalline silicon. Cov qib siv rau yav dhau los yog 421 #, 411 #, 521 # thiab 2202 #, thaum lub tom kawg siv 421 # thiab 521 #. Tam sim no, qee cov khoom siv polysilicon tuaj yeem siv 553 # thiab 441 #. Qhov no yog vim kev nce qib ntawm crystalline silicon purification technology thiab kev txiav txim siab ntawm kev lag luam kom txo tau cov nqi thiab nce efficiency. Tsis tas li ntawd, kev siv sib txawv muaj qhov yuav tsum tau ua rau cov kab kawm cov ntsiab lus ntawm cov khoom siv silicon.
