Silicon hlau 551 nrog kev ua tau zoo

Silicon hlau 551, raws li qhov tshwj xeeb lossis hom ntawm cov hlau silicon, feem ntau yog tsim los ntawm silicon (Si), thiab nws cov ntsiab lus feem ntau yog siab li 98.5% lossis ntau dua. Nws cov ntsiab lus impurity yog tsawg, xws li cov ntsiab lus ntawm hlau (Fe), txhuas (Al), calcium (Ca) thiab lwm yam khoom yog tswj nyob rau hauv ib tug tej yam ntau yam, uas ua rau silicon hlau 551 muaj zoo heev lub cev thiab tshuaj. Nws muaj cov yam ntxwv ntawm siab melting point, siab hardness, siab thermal stability, thiab zoo hluav taws xob thiab thermal conductivity.

Kev tsim cov txheej txheem ntawm silicon hlau 551 suav nrog ntau qhov sib txuas xws li kev rho tawm, crushing, sib tsoo, kev pab cuam, smelting thiab refining ntawm silicon ore. Ua ntej, silica yog muab rho tawm los ntawm silicon ore thiab crushed thiab hauv av kom tau silica hmoov. Tom qab ntawd, silica hmoov yog tov nrog ib tug txo tus neeg sawv cev xws li coke thiab muab tso rau hauv ib tug high-kub hluav taws xob rauv rau smelting. Thaum qhov kub thiab txias, silica reacts chemically nrog coke los tsim cov hlau silicon. Thaum kawg, los ntawm kev ua kom txias, sib cais thiab ua kom zoo dua qub, cov hlau purity silicon hlau 551 tau txais.

Kev ua lag luam tus nqi ntawm silicon hlau 551 yog cuam tshuam los ntawm ntau yam, xws li cov khoom siv raw, tus nqi tsim khoom, cov khoom siv thiab kev xav tau kev sib raug zoo thiab txoj cai ib puag ncig. Nrog rau kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis thiab kev txhim kho kev lag luam, daim ntawv thov kev lag luam ntawm silicon hlau 551 tau nthuav dav tas li thiab kev lag luam xav tau tseem loj hlob. Nyob rau tib lub sijhawm, cov cuab yeej tsim khoom ntawm silicon hlau 551 kuj tseem txhim kho tas li, thiab cov nqi tsim khoom tau maj mam txo, uas ua rau kev lag luam kev sib tw ntawm silicon hlau 551 nce ntxiv.

Silicon hlau 551 yog dav siv nyob rau hauv ntau lub teb vim nws siab purity thiab zoo heev lub cev thiab tshuaj. Silicon hlau 551 yog ib qho tseem ceeb raw khoom rau kev tsim khoom semiconductor xws li polycrystalline silicon thiab monocrystalline silicon. Cov khoom siv semiconductor no tau siv dav hauv kev sib xyaw ua ke, lub hnub ci hlwb thiab lwm yam haujlwm. Silicon hlau 551 tuaj yeem siv los tsim cov khoom siv hlau xws li silicon-aluminium alloy thiab silicon-hlau alloy. Cov ntaub ntawv alloy no ua lub luag haujlwm tseem ceeb hauv aerospace, tsheb tsim, tshuab tsim thiab lwm yam haujlwm. Silicon hlau 551 kuj tseem siv tau los tsim cov roj hmab silicone, silicone resin, silicone roj thiab lwm yam organosilicon tebchaw. Cov organosilicon tebchaw no yog siv dav hauv sealing, lubrication, bonding, coatings thiab lwm yam teb. Silicon hlau 551 kuj tseem siv tau los tsim cov khoom siv hluav taws xob, cov khoom siv hluav taws xob zoo silicon hlau thiab cov khoom siv hnub ci photovoltaic. Nrog rau kev nce qib ntawm thev naus laus zis thiab kev txhim kho ntawm kev lag luam, kev lag luam kev cia siab ntawm silicon hlau 551 yuav dav dua.
