Metallurgical Silicon Hlau

Silicon yog dav siv nyob rau hauv smelting ferrosilicon alloys li alloying ntsiab nyob rau hauv cov hlau thiab steel kev lag luam thiab raws li txo cov neeg sawv cev nyob rau hauv ntau yam hlau smelting. Silicon kuj yog ib qho zoo tivthaiv hauv aluminium alloy, thiab feem ntau ntawm cov cam khwb cia aluminium alloys muaj silicon.

Khoom Description

Thawj silicon integrated circuits tau tsim nyob rau hauv 1960s thiab, los ntawm 1970s, silicon-muaj processors tau tsim. Muab hais tias silicon-based semiconductor thev naus laus zis tsim cov pob txha ntawm cov khoom siv hluav taws xob niaj hnub thiab kev suav, nws yuav tsum tsis muaj qhov xav tsis thoob uas peb xa mus rau lub hub ntawm kev ua haujlwm rau kev lag luam no li 'Silicon Valley.'

Metallurgical Silicon Metal

1954: Thawj silicon photovoltaic (hnub ci) cell. Ua ntej no, kev xav ntawm kev siv lub zog los ntawm lub hnub los tsim lub zog hauv ntiaj teb tau ntseeg tias tsis tuaj yeem los ntawm feem ntau. Tab sis tsuas yog plaub xyoos tom qab, nyob rau hauv 1958, thawj satellite powered by silicon solar cells tau orbiting lub ntiaj teb.

Los ntawm xyoo 1970, cov ntawv thov kev lag luam rau hnub ci thev naus laus zis tau loj hlob mus rau cov ntawv thov hauv av xws li hluav taws xob teeb pom kev zoo ntawm ntug hiav txwv roj-rigs thiab kev tsheb ciav hlau hla. Ob xyoo dhau los, kev siv lub hnub ci zog tau loj hlob exponentially. Niaj hnub no, silicon-based photovoltaic technologies suav txog li 90 feem pua ntawm lub ntiaj teb hnub ci kev lag luam.
