Cov khoom lag luam
Nyob rau hauv lub qhov txheej txheem loj ntawm kev lag luam metallurgical, hlau silicon 553 yog zoo li tus yuam sij qis tab sis tsis tseem ceeb tab sis tsis tseem ceeb cawb. Qhov no metallurgical-qib silicon cov khoom nrog cov lus silicon ntawm txog kev lag luam xws li cov khoom siv hluav taws xob xws li txhuas alloys, silic zog, thiab hnub ci zog. Raws li cov neeg tseem ceeb ntawm cov khoom siv metallurgical, cov roj ntsha li cas thiab tshuaj lom neeg thiab cov roj ntsha thiab cov khoom lag luam sib luag "hauv cov khoom muaj kev tiv thaiv niaj hnub.
Tus naj npawb ntawm cov hlau silicon 553 muaj cov lej lag luam: "Pib sawv cev cov ntsiab lus hlau tsawg dua los yog sib npaug. 5%, thiab") yog hais txog}. 5%}. 3%. Qhov no meej tswj cov tshuaj lom neeg ntawm cov khoom siv tshuaj lom neeg ua rau nws los qhia cov nqi zoo tshaj plaws hauv cov ntawv thov metallurgical. Hauv daim teb ntawm txhuas alloy tsim, hlau silicon 553, tuaj yeem txhim kho fluidity, corrosion tsis kam thiab tshuab zog ntawm cov alloy. Thaum silicon yog sib xyaw ua ke rau hauv cov qauv txhuas, cov qauv utectic tsim ua kom cov khoom siv sib txawv thiab cov khoom siv tsis tseem ceeb, cov kab ke cav thiab lwm yam.
Niaj hnub no, nrog lub booming photovoltaic kev lag luam, hlau silaalon 553 tau dhau los ua thawj daim ntawv ntawm polysilicon raw khoom. Txawm hais tias nws yuav tsum tau yauv ua kom ncav cuag txoj cai ntawm cov qauv hluav taws xob-tshuaj lom neeg cov qauv ntawm cov qauv ntawm kev ua kom muaj txiaj ntsig zoo. Nws yog tsim nyog sau cia tias Suav teb, zoo li lub ntiaj teb tsim cov hlau silicon 553, nyiaj ntau rau txog 70% ntawm lub ntiaj teb cov zis tag nrho. Cov kev lag luam zoo no tsis yog lav cov kev thov hauv tsev hauv tsev hauv tsev, tab sis kuj muaj kev cuam tshuam deb ntawm ntiaj teb silicon khoom siv saw hlau.
Cov txheej txheem ntau lawm ntawm cov hlau silicon 553 nws tus kheej yog qhov concerto ntawm lub zog thiab chemical. Cov pa roj carbon thermal txo cov tshuaj tiv thaiv tau tawm hauv cov khoom siv hluav taws xob ua haujlwm tsis yog tsuas yog ntsuas cov roj hmab siab, tab sis kuj tseem muaj kev sib tw rau cov peev txheej siv tau. Nyob rau hauv xyoo tsis ntev los no, nrog kev txhim kho ntawm kev tiv thaiv ib puag ncig, cov hlau silicon 553 kev hloov pauv ntawm "kev siv hluav taws xob ntau thiab cov pa hluav taws xob siab" rau cov khoom lag luam ntsuab thiab qis. Cov chaw ua lag luam ntau lawm nyob rau hauv cov yunnanze thiab sichuan tau rov kho dua txoj kev loj hlob ntawm cov kev lag luam zoo thiab kev txhim kho cov txheej txheem.
