Khoom Description
Lub ntsiab ntawm cov hlau silicon 2202 yog silicon, thiab nws cov ntsiab lus feem ntau yog siab dua 99.0%. Ntxiv rau silicon, hlau silicon 2202 kuj tseem muaj cov kab tsis huv xws li hlau (Fe), txhuas (Al), calcium (Ca), thiab lwm yam, tab sis cov ntsiab lus ntawm cov impurities no yog tswj nruj me ntsis kom ntseeg tau tias cov khoom tsis huv. siab purity ntawm hlau silicon 2202. Tshwj xeeb, cov ntsiab lus hlau hauv cov hlau silicon 2202 tsis tshaj 0.2%, cov ntsiab lus txhuas tsis tshaj 0.2%, thiab cov ntsiab lus calcium tsis tshaj 0.02%.
Hlau silicon 2202 yog tsim los ntawm smelting, uas yog, silica (tsuas yog silicon dioxide) yog siv los ua raw khoom, tom qab ntxuav, tshuaj ntsuam thiab ziab, nws yog melted ntawm kub kub nyob rau hauv lub submerged arc rauv nrog ib tug txo tus neeg sawv cev (xws li qis- ash petroleum coke lossis asphalt coke, charcoal lossis ntoo blocks, thiab lwm yam). Thaum lub sij hawm smelting txheej txheem, cov khoom silicon nyob rau hauv lub silica yog txo mus rau lub metallic silicon 2202.
Hlau silicon 2202 muaj qhov tsaus grey luster, siab melting point, zoo kub tsis kam, siab resistivity, thiab siab oxidation kuj. Cov khoom siv lub cev no ua rau cov hlau silicon 2202 dav siv hauv ntau qhov chaw. Piv txwv li, Hlau silicon 2202 yog ib qho tseem ceeb raw khoom rau high-purity semiconductor cov ntaub ntawv thiab yuav siv tau los tsim polycrystalline silicon thiab ib tug siv lead ua silicon. Cov ntaub ntawv semiconductor no muaj ntau yam kev siv hauv kev lag luam photovoltaic thiab kev lag luam hluav taws xob, xws li kev tsim cov hnub ci hlwb thiab kev sib xyaw ua ke. Hlau silicon 2202 yog cov khoom siv tseem ceeb rau kev tsim cov txhuas alloys. Los ntawm kev ntxiv cov hlau silicon 2202, cov khoom siv kho tshuab, corrosion kuj thiab thermal stability ntawm aluminium alloys tuaj yeem txhim kho tau zoo. Thaum smelting tshwj xeeb steel thiab non-ferrous alloys, metallic silicon 2202 kuj yog siv los ua deoxidizer, pab txhim kho qhov zoo thiab kev ua haujlwm ntawm cov hlau. Hlau silicon 2202 tuaj yeem siv los tsim cov roj hmab silicone, silicone roj, silicone resin thiab lwm cov organic silicon tebchaw. Cov organosilicon tebchaw no tau siv dav hauv txheej txheej, yas, roj hmab thiab lwm yam lag luam, xws li sealants, lubricants, txheej additives, thiab lwm yam.
Nws kuj tseem tuaj yeem siv los ua cov khoom siv refractory, xws li silica cib, siliceous refractory av nkos, thiab lwm yam. Cov ntaub ntawv no tau siv dav hauv kev lag luam kub kub xws li steel, nonferrous hlau, iav, thiab cement. Tsis tas li ntawd, nws yog xim hlau silicon 2202 kuj tuaj yeem siv los tsim cov khoom sib xyaw xws li ferrosilicon alloys thiab silicon-aluminium alloys, nrog rau kev npaj ntawm silicides hauv kev lag luam tshuaj.
