Daim ntawv thov Praseodymium oxide
1: 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.
2: Cheebtsam ntawm lub iav Didymium uas yog xim rau cov iav tsom iav, kuj yog ib qho tseem ceeb ntxiv ntawm Praseodymium daj pigments.
3: Praseodymium Oxide nyob rau hauv cov khoom tov nrog ceria, los yog nrog ceria-zirconia, tau siv los ua oxidation catalysts.4: Nws tuaj yeem siv los tsim cov hlau nplaum uas muaj zog heev rau lawv lub zog thiab kav ntev.
