Product Description
Praseodymium Oxide Formula: Pr6O11
CAS No.: 12037-29-5
Molecular Weight: 1021.43
Appearance: Brown powder
Solubility: Insoluble in water, moderately soluble in strong mineral acids
Stability: Slightly hygroscopic
Application: Praseodymium Oxide, also called Praseodymia, used to colour glasses and enamels; When mixed with certain other materials, praseodymium produces an intense clean yellow colour in glass. Component of didymium glass which is a colourant for welder's goggles, also as important additive of Praseodymium yellow pigments.
