Nws yog xim pob zeb hlau Silicon

Silicon yog dav siv nyob rau hauv smelting ferrosilicon raws li alloying keeb hauv kev lag luam hlau thiab hlau thiab raws li txo tus neeg sawv cev nyob rau hauv ntau hom hlau smelting. Silicon tseem yog ib qho khoom siv zoo hauv cov txhuas alloys, feem ntau ntawm cov cam khwb cia alloys alloys muaj silicon. Silicon yog cov khoom siv ntawm ultrapure silicon hauv kev lag luam hluav taws xob. Cov khoom siv hluav taws xob ua los ntawm ultrapure semiconductor ib leeg siv lead ua silicon muaj qhov zoo ntawm lub ntim me, lub teeb yuag, kev ntseeg tau zoo thiab lub neej ntev. High-power transistors, rectifiers thiab cov hnub ci hlwb ua los ntawm silicon ib cov ntawv ci doped nrog cov kab uas tsis paub meej zoo dua li cov uas tau ua los ntawm Germanium cov muaju. Amorphous silicon lub hnub ci kev tshawb fawb kev kawm tau sai sai, qhov kev hloov pauv ntawm ntau dua 8%. Qhov kub siab tshaj plaws ntawm silicon-molybdenum bar hluav taws xob cua sov lub zog tuaj yeem ncav cuag 1700 ° C, nws muaj qhov tsis kam yooj yim rau kev laus thiab zoo oxidation tsis kam. Trichlorosilane, ua los ntawm silicon, tuaj yeem siv los ua kom pua ​​pua kua roj silicone thiab cov dej tsis huv. Tsis tas li ntawd, silicon carbide tuaj yeem siv cov kua hluav taws xob, thiab quartz raj ua los ntawm cov siab-purity silicon oxide yog cov khoom tseem ceeb rau kev ua kom zoo siab hlau smelting thiab teeb pom kev zoo. Daim Ntawv ntawm 1980s - Silicon tau hu ua" ntawv ntawm 1980s" Cov. Qhov no yog vim hais tias daim ntawv tuaj yeem tsuas sau cov ntaub ntawv, whereas silicon tsis tuaj yeem tsuas sau cov ntaub ntawv, tab sis kuj txheej txheem nws kom tau txais cov ntaub ntawv tshiab. Ua xyoo 1945, lub ntiaj teb' s thawj lub computer, nrog 18,000 hlab, 70,000 resistors thiab 10,000 capacitors, hnyav 30 tons thiab them thaj tsam ntawm 170 square metres, qhov loj me ntawm 10 lub tsev. Niaj hnub no' s khoos phis tawm, ua tsaug rau kev nce qib hauv kev siv thev naus laus zis thiab cov khoom siv txhim kho, muaj peev xwm tuav tau kaum txhiab tus transistors ntawm silicon wafer qhov luaj li cas ntawm cov rau tes, thiab muaj cov haujlwm ntau nrog rau kev tawm tswv yim, tsim tawm, suav, cia thiab tswj ntawm cov ntaub ntawv. Microporous calcium silicate thermal rwb thaiv tsev cov khoom yog cov khoom siv zoo rwb thaiv tsev thermal. Tus qauv tsim hluav taws xob muaj qhov zoo ntawm kev muaj peev xwm kub me me, lub zog ntawm lub zog loj, tsis muaj cua sov tsis zoo, tsis sib xyaw, tsis muaj tshuaj lom thiab tsis qab, txiav, kev thauj mus los yooj yim, thiab lwm yam. Tom qab sim, lub zog-txuag cov txiaj ntsig tshaj li asbestos, cement, vermiculite thiab cement perlite rwb thaiv cov ntaub ntawv. Cov khoom siv tshwj xeeb silica-calcium tuaj yeem siv los ua cov cab hauv cov roj av, thiab siv dav hauv cov roj av ua kom zoo, kev ua kom lub tsheb tso pa tawm thiab lwm yam.
