Ua ntej, cia peb saib cov txheej txheem kev npaj ntawm hlau silicon hmoov. Metallic silicon hmoov yog cov hmoov zoo uas ua los ntawm cov khoom siv hlau silicon rau cov txheej txheem ua haujlwm. Ntawm lawv, txoj kev siv feem ntau yog txoj kev txo silica. Tom qab crushing thiab tshuaj ntsuam, cov silica yog tov nrog metallurgical silicon thiab charcoal, thiab ces ntxiv rau lub cub hluav taws xob rau cov tshuaj tiv thaiv nyob rau hauv lub txo qhov cub. Thaum kub kub, cov oxides hauv silica raug txo rau silicon los tsim cov hmoov hlau silicon hmoov. Tsis tas li ntawd, muaj lwm yam kev npaj, xws li txoj kev silicate thiab txoj kev pyrolysis.
Cov txheej txheem kev npaj sib txawv muaj qhov cuam tshuam ncaj qha rau qhov zoo ntawm cov khoom tiav hlau silicon hmoov. Ua ntej ntawm tag nrho cov, qhov zoo ntawm cov txheej txheem txo yuav cuam tshuam rau purity ntawm hlau silicon hmoov. Siv high-purity raw cov ntaub ntawv thiab tsim nyog txo qhov kub thiab lub sij hawm yuav txhim khu lub purity ntawm hlau silicon hmoov thiab txo cov ntsiab lus ntawm impurities. Thib ob, cov txheej txheem txo kuj tseem cuam tshuam rau qhov loj me thiab morphology ntawm cov hmoov hlau silicon hmoov. Los ntawm kev tswj cov kev txo qis, nws yog xim hlau silicon hmoov ntawm qhov sib txawv particle loj tuaj yeem ua tau raws li qhov xav tau ntawm cov ntawv thov sib txawv. Tsis tas li ntawd, cov txheej txheem txo qis kuj cuam tshuam rau daim ntawv siv lead ua thiab cov qauv ciam teb ntawm cov xim hlau silicon hmoov, ntxiv rau nws lub cev thiab tshuaj lom neeg.
Ntxiv nrog rau cov txheej txheem kev npaj, cov khoom lag luam zoo ntawm cov hlau silicon hmoov kuj tseem cuam tshuam los ntawm cov khoom siv raw thiab cov txheej txheem tom ntej. Qhov purity thiab particle loj ntawm cov ntaub ntawv raw yuav cuam tshuam ncaj qha rau qhov zoo ntawm cov khoom tiav ntawm cov hmoov hlau silicon hmoov. Nyob rau tib lub sijhawm, kev tshuaj ntsuam tom ntej, ziab thiab ntim cov txheej txheem yuav tsum yog kev tshawb fawb thiab tsim nyog los xyuas kom meej qhov zoo thiab ruaj khov ntawm cov hmoov hlau silicon hmoov.
Cov txheej txheem kev npaj ntawm cov hmoov hlau silicon hmoov muaj qhov cuam tshuam tseem ceeb ntawm cov khoom zoo. Los ntawm kev ua kom zoo ntawm cov txheej txheem kev npaj, tswj cov khoom siv raw zoo thiab txhim kho cov txheej txheem tom ntej, qhov purity, particle tis thiab grain ciam qauv ntawm cov hlau silicon hmoov tuaj yeem txhim kho, yog li ua tiav cov khoom zoo.
Hlau silicon hmoov yog cov khoom siv feem ntau siv hauv kev tsim khoom, thiab nws cov txheej txheem kev npaj muaj feem cuam tshuam rau cov khoom zoo. Kab lus no yuav qhia txog cov txheej txheem kev npaj ntawm cov hmoov hlau silicon hmoov thiab sib tham txog nws qhov cuam tshuam rau cov khoom zoo. Los ntawm kev ua kom zoo ntawm cov txheej txheem kev npaj, tswj cov khoom siv raw zoo thiab txhim kho cov txheej txheem tom ntej, qhov purity, particle tis thiab grain ciam qauv ntawm cov hlau silicon hmoov tuaj yeem txhim kho, yog li ua tiav cov khoom zoo.
