Kev Siv Hlau Silicon

Ib tug loj npaum li cas ntawm silicon yog siv rau smelting rau hauv ferrosilicon alloy raws li ib tug alloying caij nyob rau hauv cov hlau thiab steel kev lag luam, thiab raws li ib tug txo tus neeg sawv cev nyob rau hauv lub smelting ntawm ntau yam hlau. Silicon kuj yog ib qho zoo tivthaiv hauv txhuas alloys, thiab feem ntau cam khwb cia txhuas alloys muaj silicon. Silicon yog raw khoom ntawm ultra-ntshiab silicon nyob rau hauv electronics kev lag luam. Cov khoom siv hluav taws xob ua los ntawm ultra-ntshiab semiconductor ib leeg siv lead ua silicon muaj qhov zoo ntawm qhov me me, lub teeb yuag, kev ntseeg tau zoo thiab lub neej ntev. High-power transistors, rectifiers thiab solar cells 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 nce sai, thiab kev hloov pauv tau mus txog ntau dua 8 feem pua. Qhov siab tshaj plaws ua haujlwm kub ntawm silicon molybdenum pas nrig hluav taws xob cua sov tuaj yeem ncav cuag 1700 degree, thiab nws muaj kev tiv thaiv kev laus thiab kev ua haujlwm zoo los tiv thaiv oxidation. Trichlorosilane, tsim los ntawm silicon, tuaj yeem tsim nrog ntau pua ntawm silicone lubricants thiab cov dej tsis sib haum. Tsis tas li ntawd, silicon carbide tuaj yeem siv los ua abrasive, thiab quartz raj ua los ntawm high-purity silicon oxide yog cov khoom tseem ceeb rau high-purity hlau smelting thiab teeb pom kev zoo fixtures. Daim ntawv hauv xyoo 1980 - Silicon Silicon yog hu ua "daim ntawv ntawm xyoo 1980". 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 cov ntaub ntawv kom tau txais cov ntaub ntawv tshiab. Lub ntiaj teb thawj lub tshuab hluav taws xob tsim tawm xyoo 1945 yog nruab nrog 18, 000 raj, 70,{15}} resistors thiab 10,{17}} capacitors. Tag nrho lub tshuab hnyav 30 tons thiab npog thaj tsam ntawm 170 square metres, sib npaug rau qhov loj ntawm 10 lub tsev. Niaj hnub no cov khoos phis tawj hluav taws xob, vim kev nce qib ntawm kev siv thev naus laus zis thiab kev txhim kho cov khoom siv, tuaj yeem ua kom haum rau kaum tawm txhiab tus transistors ntawm silicon nti qhov loj ntawm tus ntiv tes; thiab muaj cov haujlwm ua haujlwm xws li kev tawm tswv yim, tso tawm, suav, khaws cia thiab tswj cov ntaub ntawv. Microporous silica-calcium thermal rwb thaiv tsev khoom Microporous silicon-calcium thermal rwb thaiv tsev cov ntaub ntawv yog ib qho zoo heev thermal rwb thaiv tsev cov ntaub ntawv. Nws muaj cov yam ntxwv ntawm me me tshav kub muaj peev xwm, siab mechanical zog, tsawg thermal conductivity, tsis-flammable, non-toxic thiab tasteless, yuav txiav, thiab yooj yim rau thauj. Tom qab kev sim, cov nyhuv txuag hluav taws xob zoo dua li cov ntaub ntawv thermal rwb thaiv tsev xws li asbestos, cement, vermiculite thiab cement perlite. Cov ntaub ntawv tshwj xeeb silicon-calcium tuaj yeem siv los ua cov khoom siv catalyst thiab dav siv hauv roj av refining, tsheb purification thiab lwm yam.
