cov ntsiab lus ntawm silicon mrtal hmoov
Qhov zoo:
1. High purity: Hlau silicon hmoov tuaj yeem muaj qhov purity siab, feem ntau ncav cuag ntau tshaj 99%. Qhov no ua rau nws muaj nuj nqis tseem ceeb hauv qee qhov kev lag luam tshwj xeeb, xws li hluav taws xob, photovoltaics thiab lwm yam haujlwm.
2. Fine particles: qhov me me ntawm cov hmoov hlau silicon hmoov feem ntau yog me me thiab tuaj yeem hloov kho raws li qhov xav tau. Qhov no ua rau cov hmoov hlau silicon yooj yim rau kev sib tov, tawg thiab hnov mob hauv qee cov txheej txheem, thiab txhim kho nws daim ntawv thov.
3. Zoo conductivity: hlau silicon hmoov muaj zoo conductivity thiab yog haum rau hluav taws xob Cheebtsam, semiconductor ntaub ntawv thiab lwm yam teb. Nws tuaj yeem siv los ua cov khoom siv hluav taws xob lossis cov khoom ntxiv los muab txoj hauv kev tam sim no.
4. Thermal stability: Hlau silicon hmoov muaj thermal stability zoo thiab tuaj yeem ua kom nws lub cev thiab tshuaj lom neeg ruaj khov ntawm qhov kub thiab txias. Qhov no ua rau nws siv dav hauv cov txheej txheem kub kub, xws li metallurgy, refractories thiab lwm yam kev lag luam.
Qhov tsis zoo:
1. Yooj yim rau oxidize: hlau silicon hmoov yog ib qho yooj yim rau oxidize hauv huab cua los ua silicon dioxide. Qhov no yuav txo nws cov hluav taws xob conductivity thiab lwm yam ntxwv, thiab kev ntsuas yuav tsum tau coj los tiv thaiv los yog ruaj khov.
2. Plua plav phom sij: nws yog xim hlau silicon hmoov yog ib yam khoom zoo, uas yuav ua rau khaus thiab ua rau lub ntsws thiab tawv nqaij puas tsuaj yog nqus tau los yog tiv nrog tib neeg lub cev. Yog li ntawd, nws yog ib qho tsim nyog yuav tau xyuam xim rau kev tiv thaiv kev nyab xeeb thiab kev tiv thaiv tus kheej thaum siv cov hmoov hlau silicon hmoov.
3. Tus nqi siab dua: Piv nrog rau lwm cov khoom siv hlau, cov txheej txheem kev npaj ntawm cov hmoov hlau silicon hmoov yog qhov nyuaj thiab tus nqi siab dua. Qhov no ua rau kev siv cov hmoov hlau silicon hmoov hauv qee daim ntawv thov kev txwv los ntawm kev lag luam.
npaj txoj kev ntawm silicon hlau hmoov
Muaj ob txoj hauv kev los npaj cov hmoov hlau silicon hmoov, uas yog txoj kev siv lub cev thiab cov txheej txheem tshuaj. Ntawm lawv, txoj kev siv lub cev muaj xws li calcination method thiab gas phase method. Cov txheej txheem calcination yog tsuas yog ua kom sov cov khoom siv silicon rau qhov kub thiab txias, thiab tom qab ntawd maj mam txias nws hauv qhov chaw tsis muaj zog kom tau txais cov hmoov zoo hlau silicon hmoov. Txoj cai roj theem yog tias cov khoom siv silicon yog siv los ua cov khoom siv raw, uas yog gasified rau hauv cov tshuaj silicon los ntawm cov tshuaj tiv thaiv thiab tso rau ntawm qhov kub thiab txias, yog li tau txais cov hmoov hlau silicon hmoov. Txoj cai lij choj tshuaj lom neeg yog txhawm rau txo cov khoom siv silicon rau hauv cov hlau silicon los ntawm cov tshuaj tiv thaiv, yog li tau txais cov hmoov hlau silicon hmoov.
