Qhov zoo ntawm 2202:
Exceptionally tsawg impurity theem (Fe Tsawg dua los yog sib npaug rau 0.20%, Al Tsawg dua los yog sib npaug rau 0.20%, Ca Less dua los yog sib npaug rau 0.02%) thiab Si Ntau dua los yog sib npaug rau 99.5%, txo cov paug paug hauv cov txheej txheem qis.
Qhov zoo tshaj plaws rau siab -tus nqi, purity- cov ntaub ntawv rhiab heev xws li hnub ci- qib polysilicon, hwm organosilicon monomers (xws li, siab-kev ua tau zoo silicones), thiab cov khoom siv tshwj xeeb silicon-.
Ua kom cov khoom zoo sib xws, txo qis tus nqi, thiab tus nqi ntxiv hauv cov lag luam hwm.
Qhov zoo ntawm 3303:
Tus nqi zoo tshaj -kev ua tau zoo, feem ntau 15-35% pheej yig dua li 2202, muab kev txuag nyiaj rau cov nqi raw khoom.
Kev tswj tsis zoo txaus (Fe Tsawg dua lossis sib npaug ntawm 0.30%, Al Tsawg dua lossis sib npaug 0.30%, Ca Tsawg dua lossis sib npaug rau 0.03%, Si ≈99.3–99.4%) rau kev txhim khu kev qha hauv feem ntau cov qauv siv.
Cov khoom lag luam ntau, ruaj khov, thiab xa khoom sai, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau cov khoom siv hluav taws xob loj, aluminium alloy casting, dav hlau metallurgy, thiab nruab nrab -ntau cov saw hlau polysilicon.
Hauv luv luv: 2202 excels hauv ultra-purity thiab premium positioning; 3303 yeej ntawm kev ua tau zoo, kev ntseeg tau, thiab kev lag luam.
