Chromium (Cr) Cov ntaub ntawv dav dav:
Chromium, lus Askiv lub npe Chromium, lub cim cim Cr, belongs rau VIB pawg hlau ntsiab nyob rau hauv lub sij hawm lub sij hawm ntawm lub ntsiab lus, atomic tooj 24, atomic hnyav 51.996, ceev 7.19g / cm³, melting point 1857 ± 20 ℃, boiling point 2672 ℃. Lub cev-centered cubic crystals, ntau valences yog +3, +6 thiab +2, thiab lub zog ionization yog 6.766 electron volts. Chromium yog cov hlau dawb-dawb uas tsis tshua muaj zog, nkig, thiab corrosion-resistant. Nws yog cov hlau tsis muaj zog thiab ruaj khov rau oxygen thiab noo noo ntawm chav tsev kub. Cov ntsiab lus ntawm chromium nyob rau hauv lub ntiaj teb crust yog 0.01%, qeb duas 17th. Dawb chromium tsis muaj nyob rau hauv qhov, thiab lub ntsiab chromium-muaj ore yog chromite.

Chromium (Cr)Hlau Element Txheej txheem cej luam:

Peb smelts ib yam ntawm cov hlau thiab feem ntau lwm cov ntaub ntawv siab heev rau hauv pas nrig, bar los yog phaj daim ntawv, los yog cov neeg muas zaub muab cov khoom kos duab.
Peb muag cov khoom sib txawv ntawm chromium emetal cov ntaub ntawv los ntawm chav tsev hnyav lossis ib thooj rau kev siv sib txawv hauv cheeb tsam tshawb fawb thiab rau cov cuab yeej tshiab.

Piv txwv li: Chromium Bar, Chromium Qws, Chromium Phaj, Chromium Sheet, Chromium Tube, Chromium Pipe, Chromium Ingot, Chromium Lump, Chromium Pellet, Chromium Target, Chromium Cube, Customized Chromium. Lwm cov duab muaj nyob ntawm kev thov.
