Daim Ntawv Thov Oxide InaseMium
1: Preaseymium oxide, tseem hu ua preasemodymia, siv rau xim tsom iav thiab enamels; Thaum sib xyaw nrog qee cov ntaub ntawv, cov duab ua ntej tsim cov xim huv huv hauv iav.
2: Feem ntawm Didymium iav uas yog ib tug colourant rau cov hlua khi khawm, kuj tseem ceeb ntxiv ntawm cov pigerymium daj pigments.
3: Preaseymium oxide nyob rau hauv cov kev daws teeb meem nrog ceria, lossis nrog ceria-zirconia, tau siv ua cov tshuaj pleev oxidation. 4: Nws tuaj yeem siv los tsim cov hlau loj cov hlau nplaum tseem ceeb rau lawv lub zog thiab lub zog.
