Daim ntawv thov:
Praseodymium Oxide, tseem hu ua Praseodymia, siv rau xim iav thiab enamels; Thaum sib xyaw nrog lwm cov ntaub ntawv, Praseodymium ua kom muaj xim daj ntshiab hauv iav. Cov khoom siv ntawm lub iav Didymium uas yog xim rau cov iav tsom iav, kuj yog ib qho tseem ceeb ntxiv ntawm Praseodymium yellow pigments. Praseodymium Oxide hauv cov tshuaj tov nrog ceria, los yog nrog ceria-zirconia, tau siv los ua oxidation catalysts. Nws tuaj yeem siv los tsim cov hlau nplaum muaj zog uas tseem ceeb rau lawv lub zog thiab kav ntev.
