ZhenAn High Purity Silicon Carbide Hmoov
Silicon muaj ob allotropes: amorphous silicon thiab crystalline silicon. Amorphous silicon yog grey-dub hmoov, uas yog tiag tiag microcrystal. Crystalline silicon muaj cov qauv siv lead ua thiab cov khoom siv semiconductor ntawm pob zeb diamond, nrog lub melting point ntawm 1410 degree, ib tug boiling point ntawm 2355 degree, ib tug ceev ntawm 2.32 ~ 2.34g / cm3, ib tug Mohs hardness ntawm 7, thiab ib tug nkig xwm. Chemical silicon hais txog cov xim hlau silicon siv hauv kev tsim cov organic silicon thiab polycrystalline silicon.
Hlau Silicon Powder
Los ntawm kev xav thoob ntiaj teb, kev noj cov tshuaj silicon metallurgical ntau dua li kev noj cov tshuaj silicon. Txawm li cas los xij, nrog kev txhim kho txuas ntxiv ntawm kev tshawb fawb thiab thev naus laus zis, kev siv tshuaj silicon hauv thaj chaw xws li organic silicon thiab semiconductor ntau lawm txuas ntxiv nthuav dav, thiab nws tau siv dav hauv kev tsim cov organic silicon. Silicon monomer thiab polymersilicone roj, silicone roj hmab, silicone resin tsev tiv thaiv corrosion thiab waterproofing agents, thiab lwm yam, muaj cov yam ntxwv tshwj xeeb xws li kub tsis kam, hluav taws xob rwb thaiv tsev, hluav taws xob tiv thaiv, thiab waterproofing. Siv nyob rau hauv hluav taws xob, aviation, machinery, tshuaj lom neeg kev lag luam, tshuaj, lub teb chaws tiv thaiv, kev tsim kho thiab lwm yam sectors. Raws li cov khoom siv hluav taws xob tseem ceeb ntawm kev sib xyaw ua ke, ntau dua 95% yog ua los ntawm cov khoom siv hluav taws xob silicon. Semiconductors yog lub hauv paus ntawm cov ntaub ntawv kev lag luam niaj hnub no.
Silicon Hlau Powder Lab Qib
Amorphous siliconyog tshuaj lom neeg thiab tuaj yeem hlawv hnyav hauv oxygen. Nws reacts nrog cov hlau tsis muaj hlau xws li halogen, nitrogen, thiab carbon ntawm qhov kub thiab txias, thiab tuaj yeem ua rau cov hlau xws li magnesium, calcium, thiab hlau los tsim cov silicides. Amorphous silicon yuav luag insoluble nyob rau hauv tag nrho cov inorganic thiab organic acids, nrog rau hydrofluoric acid, tab sis yog soluble nyob rau hauv ib tug tov ntawm nitric acid thiab hydrofluoric acid. Concentrated sodium hydroxide tov tuaj yeem yaj amorphous silicon thiab tso cov roj hydrogen. Crystalline silicon yog qhov tsis ua haujlwm thiab tsis ua ke nrog oxygen txawm tias nyob rau qhov kub thiab txias. Nws kuj yog insoluble nyob rau hauv txhua yam inorganic acid thiab organic acid, tab sis yog soluble nyob rau hauv sib xyaw acids ntawm nitric acid thiab hydrofluoric acid thiab concentrated sodium hydroxide tov.
