Daim ntawv thov
tus nqi praseodymium fluoride, yog cov khoom siv tseem ceeb rau kev ua Praseodymium Hlau, thiab tseem siv rau hauv cov iav xim thiab enamels; Thaum sib xyaw nrog lwm cov ntaub ntawv, Praseodymium ua kom muaj xim daj ntshiab hauv iav. Praseodymium yog tam sim no nyob rau hauv lub ntiaj teb tsis tshua muaj sib tov uas nws Fluoride tsim cov tub ntxhais ntawm carbon arc teeb uas yog siv nyob rau hauv lub motion picture industry rau studio teeb pom kev zoo thiab projector teeb. Doping Praseodymium hauv Fluoride iav tso cai rau nws siv los ua ib hom fiber ntau optical amplifier.
