Daim ntawv thov

Praseodymium yog ib qho mos mos malleable, silvery-daj hlau. Nws yog ib tug tswv cuab ntawm pawg lanthanide ntawm lub sij hawm ntawm lub ntsiab lus. Nws reacts maj mam nrog oxygen: thaum raug huab cua nws tsim ib tug ntsuab oxide uas tsis tiv thaiv nws los ntawm ntxiv oxidation. Nws yog ntau resistant rau corrosion nyob rau hauv huab cua lwm yam tsawg hlau, tab sis nws tseem yuav tsum tau muab cia rau hauv cov roj los yog coated nrog yas. Nws reacts sai nrog dej.
