Kev siv Silicon

Silicon yog feem ntau siv rau smelting rau hauv ferrosilicon alloys raws li ib tug alloying caij nyob rau hauv lub steel kev lag luam, thiab raws li ib tug txo tus neeg sawv cev nyob rau hauv ntau yam hlau smelting txheej txheem. Silicon kuj yog ib qho zoo tivthaiv nyob rau hauv aluminium alloys, thiab feem ntau ntawm cam khwb cia txhuas alloys muaj silicon. Silicon yog cov khoom siv raw ntawm ultrapure silicon hauv kev lag luam hluav taws xob. Cov khoom siv hluav taws xob ua los ntawm ultrapure semiconductor monocrystalline silicon muaj qhov zoo xws li ntim me me, lub teeb yuag, kev ntseeg tau zoo, thiab kev ua neej ntev. Lub zog siab transistors, rectifiers, thiab lub hnub ci hlwb ua los ntawm silicon ib leeg muaju doped nrog cov kab mob tshwj xeeb yog zoo dua li cov uas ua los ntawm germanium ib leeg muaju. Kev tshawb fawb ntawm amorphous silicon hnub ci hlwb tau ua tiav sai, nrog kev hloov pauv ntau dua 8 feem pua. Qhov siab tshaj plaws kev khiav hauj lwm kub ntawm silicon molybdenum pas nrig hluav taws xob cua sov caij tuaj yeem ncav cuag 1700 degree, uas muaj kev tiv thaiv tsis yooj yim rau hnub nyoog thiab kev ua haujlwm zoo antioxidant. Lub Trichlorosilane ua los ntawm silicon tuaj yeem siv los npaj ntau pua ntawm silicone resin lubricants thiab cov dej tsis sib haum. Tsis tas li ntawd, silicon carbide tuaj yeem siv los ua cov abrasive, thiab quartz raj ua los ntawm high-purity silicon oxide yog cov ntaub ntawv tseem ceeb rau high-purity hlau smelting thiab teeb pom kev zoo fixtures. Daim ntawv los ntawm 1980s - Silicon yog hu ua "daim ntawv los ntawm 1980s" los ntawm tib neeg. Qhov no yog vim tias daim ntawv tuaj yeem sau cov ntaub ntawv nkaus xwb, thaum silicon tuaj yeem tsis tsuas yog sau cov ntaub ntawv, tab sis kuj ua rau nws tau txais cov ntaub ntawv tshiab. Lub ntiaj teb thawj lub tshuab hluav taws xob, tsim nyob rau hauv 1945, tau nruab nrog 18000 hluav taws xob raj, 70000 resistors, thiab 10000 capacitors. Tag nrho lub tshuab hnyav 30 tons thiab npog thaj tsam ntawm 170 square meters, sib npaug rau qhov loj ntawm 10 lub tsev. Thiab niaj hnub no cov khoos phis tawj hluav taws xob, vim yog kev txhim kho thev naus laus zis thiab cov khoom siv txhim kho, tuaj yeem ua kom haum rau kaum tawm txhiab tus transistors ntawm silicon nti qhov loj ntawm tus ntiv tes; Thiab nws muaj ntau txoj haujlwm xws li kev tawm tswv yim, tso zis, suav, khaws cia, thiab tswj cov ntaub ntawv. Microporous silicon calcium rwb thaiv tsev cov ntaub ntawv yog cov khoom siv rwb thaiv tsev zoo heev. Nws muaj cov yam ntxwv ntawm me me Thaum tshav kub kub muaj peev xwm, siab mechanical zog, tsis tshua muaj thermal conductivity, tsis combustion, non-toxic thiab tasteless, txiav, yooj yim thauj, thiab lwm yam. Nws tuaj yeem siv dav hauv ntau yam khoom siv thermal thiab cov kav dej xws li metallurgy, hluav taws xob fais fab. , tshuaj lom neeg kev lag luam, nkoj, thiab lwm yam. Tom qab kev sim, cov txiaj ntsig txuag hluav taws xob zoo dua li cov ntaub ntawv rwb thaiv tsev xws li asbestos, cement, vermiculite thiab cement Perlite. Cov ntaub ntawv tshwj xeeb calcium silicate tuaj yeem siv los ua catalyst cab kuj thiab tau siv dav hauv ntau yam xws li roj av refining thiab automotive purification.
