Silicon hlau thaiv

Silicon hlau, aka crystalline silicon los yog muaj silicon, ua hauj lwm raws li ib tug tseem ceeb additive nyob rau hauv non-ferrous alloys. Nrog nws cov xim grey tab sis nws yog xim hlau, qhov no tsis yog xim hlau muaj qhov nyuaj thiab nkig. Nws cov khoom zoo heev ua rau nws yog ib qho tseem ceeb hauv kev siv ntau yam, ua kom muaj kev ua tau zoo thiab kev ntseeg siab. Xaiv cov hlau silicon rau koj cov kev xav tau uas tsis yog-ferrous alloy thiab paub qhov txawv nws tuaj yeem ua.

Peb cov hlau nplaum silicon tuaj yeem muab faib ua cov qib sib txawv.Cov qib no tau tsim tshwj xeeb los ua kom tau raws li kev xav tau ntawm ntau yam kev lag luam. Nrog peb cov khoom zoo hlau silicon, koj tuaj yeem txaus siab rau kev ua tau zoo thiab kev ntseeg siab. Peb cov khoom raug tswj xyuas nruj kom ntseeg tau tias koj tau txais cov txiaj ntsig zoo tshaj plaws. Tiv tauj peb hnub no kom paub ntau ntxiv txog peb cov khoom.

Hauv kev lag luam, silicon hlau feem ntau yog tsim los ntawm kev txo cov silicon dioxide siv cov pa roj carbon hauv lub cub hluav taws xob. Qhov sib npaug tshuaj tiv thaiv yog SiO2 + 2C → Si + 2CO. Lub purity ntawm silicon ua nyob rau hauv no txoj kev yog 97 mus rau 98%, uas yog hu ua hlau silicon. Tom qab ua tiav cov txheej txheem ntawm melting thiab recrystallizing, cov kua qaub yog ua hauj lwm los tshem tawm cov impurities, ua rau cov hlau silicon nrog ib tug purity li ntawm 99.7 mus rau 99.8%.

Txoj kev tsim khoom no suav nrog ntau cov kauj ruam tseem ceeb thiab yuav tsum muaj kev tswj xyuas meej kom ntseeg tau tias qhov zoo thiab purity ntawm cov khoom kawg. Kev siv lub qhov cub hluav taws xob muab qhov chaw tswj xyuas kom txo qhov tshwm sim tshwm sim. Kev tshem tawm cov impurities los ntawm kev kho cov kua qaub yog ib kauj ruam tseem ceeb hauv kev ua tiav cov qib siab purity siab.

Lub resulting metallic silicon pom dav daim ntawv thov nyob rau hauv ntau yam lag luam vim nws cov yam ntxwv thiab cov yam ntxwv. Nws cov purity siab ua rau nws haum rau cov kev siv tshwj xeeb uas xav tau kev ua tau zoo thiab kev ua haujlwm zoo.

Zuag qhia tag nrho, cov txheej txheem no qhia tau hais tias qhov tseem ceeb ntawm cov txheej txheem siab heev thiab kev tswj xyuas nruj heev hauv kev tsim cov khoom siv high-purity metallic silicon rau ntau hom kev lag luam.
