Cov pa roj carbon

carbon (C), nonmetallic chemical element nyob rau hauv pawg 14 (IVa) ntawm lub sij hawm.Cov pa roj carbon muaj qhov Melting Point ntawm 3550 ° C, thiab Boiling Point ntawm 4827 ° C.Nws qhia tau hais tias zoo heev stability thiab tsawg toxicity.

Nyob rau hauv lub crust ntawm lub ntiaj teb, elemental carbon yog ib feem me me.Txawm li cas los xij, cov pa roj carbon monoxide (piv txwv li, carbonates ntawm magnesium thiab calcium) tsim cov minerals (xws li magnesite, dolomite, marble, los yog limestone).Coral thiab lub plhaub ntawm oysters thiab clams feem ntau yog calcium carbonate.Cov pa roj carbon monoxide yog dav faib ua thee thiab hauv cov organic sib txuas uas tsim cov roj av, cov pa roj carbon monoxide, thiab tag nrho cov nroj tsuag thiab tsiaj cov ntaub so ntswg.Ib qho xwm txheej ntawm cov tshuaj lom neeg hu ua lub voj voog ntawm cov pa roj carbon monoxide - suav nrog kev hloov pauv ntawm atmospheric carbon dioxide rau cov carbohydrates los ntawm photosynthesis hauv cov nroj tsuag, kev noj cov carbohydrates los ntawm cov tsiaj thiab oxidation ntawm lawv los ntawm cov metabolism los tsim carbon dioxide thiab lwm yam khoom, thiab rov qab los ntawm carbon. dioxide rau huab cua - yog ib qho tseem ceeb tshaj plaws ntawm tag nrho cov txheej txheem lom.

Cov Khoom Siv Tshwj Xeeb nplua nuj yog cov chaw tsim khoom ntawm Sputtering Lub Hom Phiaj thiab tuaj yeem tsim cov purity Carbon Sputtering cov ntaub ntawv raws li cov neeg siv khoom tshwj xeeb.Yog xav paub ntxiv, thov hu rau peb.
