Vim nws qhov ua tau zoo raws li tus neeg xyuas hluav taws xob, cadmium feem ntau siv hauv electroplating thiab hauv roj teeb. Tsis tas li ntawd, cadmium thiab cov kev daws teeb meem ntawm nws cov tebchaw yog tshuaj lom thiab yuav tsum tau ua tib zoo saib xyuas.
Puas cadmium yog ib qho zoo conductor ntawm tshav kub thiab hluav taws xob?
Cadmium yog ib qho muag muag, malleable, ductile, xiav-dawb hlau, uas yooj yim txiav nrog riam. Nws yog ib qhocov khoom siv hluav taws xob zoo heev thiab qhia tau zoo tiv thaiv corrosion thiab tawm tsam los ntawm cov tshuaj. Nws zoo ib yam li zinc hauv nws cov khoom siv tshuaj.
Puas cadmium yog hlau lossis nonmetal?
Cadmium (Cd) yog soft, malleable, bluish dawb hlaupom nyob rau hauv zinc ores, thiab rau ib tug ntau tsawg npaum li cas, nyob rau hauv lub cadmium mineral greenockite. Feem ntau ntawm cov cadmium tsim hnub no yog tau los ntawm zinc byproducts thiab rov qab los ntawm siv nickel-cadmium roj teeb.
Cadmium yog dab tsi?
Cadmium yog lustrous, silver-white, ductile, malleable hlau. Nws qhov chaw muaj xim xiav thiab cov hlau yog mos txaus los txiav nrog rab riam, tab sis nws tarnishes hauv huab cua. Nws yog soluble hauv acids tab sis tsis nyob rau hauv alkalis. Nws zoo sib xws rau ntau yam ntawm zinc tab sis nws tsim ntau cov tebchaw.
Puas yog cadmium magnetic?
Lub magnetic susceptibilities ntawm cadmium manganites, (Cd x2+Mn1 -+)Mn2 3+O4,tau ntsuas ntawm 4 · 2 ° K thiab 1000 ° K ua haujlwm ntawm thaj chaw thiab qhov kub thiab txias. Tag nrho cov qauv tshwj tsis yog x=1 ua ferrimagnetic ntawm qhov kub thiab txias thiab qhia peb qhov kev hloov pauv.
