Hlau Silicon Rau Metallurgical Kev Lag Luam

Covhlau siliconua nyob rau hauv Suav teb (silicon cov ntsiab lus yog feem ntau 98.5%) yog Ameslikas mas metallurgical silicon. Kev tsim cov tshuaj silicon hlau (silicon cov ntsiab lus feem ntau yog 99.85%) tau tsim los txij li nruab nrab -1990s. kuv lub teb chaws cov tshuaj silicon Cov zis thiab export ntim loj hlob sai heev. Txij xyoo 1999 txog 2001, kuv lub teb chaws cov tshuaj silicon xa tawm mus rau Nyiv tau mus txog 22, 000 tons, 30, 000 tons, thiab 40,{12}} tons raws li. Nyob rau hauv 2001, kuv lub teb chaws cov tshuaj silicon exported rau Nyiv accounted rau ntau tshaj 40% ntawm Nyiv cov tshuaj silicon imports. . Tuam Tshoj tau pib koom nrog cov qib ntawm cov tshuaj silicon cov neeg tsim khoom thiab cov chaw muag khoom, thiab cov tuam txhab tsim cov tshuaj silicon ntau ntxiv. Txij li thaum Shanghai Guangji Silicon Materials Co., Ltd. tau nthuav tawm tag nrho cov txheej txheem carbothermal txo smelting hauv xyoo 2002, Tuam Tshoj tus silicon hlau tsim muaj peev xwm tau nce sai ntawm 100, 000 tons hauv ib xyoos rau 1.2 lab tons ntawm 2002 thiab 2004.
