Lub ntsiab tseem ceeb ntawm silicon hlau 441 yog crystalline silicon. Thaum xub thawj, cov khoom muaj ib tug lumpy zoo thiab ib tug kuj ruaj khov xim. Tom qab ua haujlwm ntawm kev sib tsoo lossis sib tsoo, cov khoom hloov pauv mus rau lub xeev powdery thiab feem ntau ua tsis muaj zog.
Cov sodium hydroxide catalyst feem ntau yog siv nrog rau silica hmoov dissolution txoj kev los npaj ib tug silica tov nrog ib tug silica ntsiab lus ntau tshaj 30%. Cov txheej txheem no yields ntau tshaj 80% silica tov, tseem hu ua silicate hydrosol los yog silica hydrosol. Qhov kev daws teeb meem no pom kev siv dav hauv kev lag luam xws li precision casting, catalyst carriers, ntawv, textiles, thiab lwm yam. Cov txheej txheem ntawm kev npaj silica hlau hmoov yog yooj yim thiab cov hauv paus ntsiab lus yog qhov tseeb.
Los ntawm dispersing ib tug npaum li cas ntawm crude silicon hmoov nrog ib tug inert roj nyob rau hauv ib tug plasma arc, crude silicon hmoov raug kub siab, uas ua rau nws mus vaporise instantly rau hauv silicon vapour. Cov vapor no ces nkag mus rau nanoscale condensation nyob rau hauv qhov chaw txias kom tsim tau lwm cov hmoov hlau silicon. Nws yuav tsum tau muab sau tseg tias qee qhov impurity Cheebtsam yuav raug tsim thaum lub sij hawm silicon hlau hmoov txheej txheem. Yuav kom tau txais cov ntshiab silicon hlau hmoov, cov impurities yuav tsum tau muab tshem tawm zoo. Hlau silicon yog cov ntshiab heev, industrially purified monolithic silicon. Nws yog tsuas yog siv rau kev tsim cov silicon, uas yog siv nyob rau hauv 3C kev lag luam. Ntxiv nrog rau kev tsim cov khoom siv hluav taws xob siab purity semiconductor, nws kuj tuaj yeem siv los ua cov hom phiaj tshwj xeeb. Thaum yuav cov khoom siv, peb pom zoo kom xaiv cov chaw tsim khoom txhim khu kev qha. Qhov zoo ntawm cov ntaub ntawv tsim nyob rau hauv peb lub Hoobkas yog guaranteed.
