Beschreibung

Praseodymium Oxide, or praseodymia, is a dark brown powder that is insoluble in water and only in strong acids. Praseodymium Oxide is stable under average temperatures and pressures. Praseodymium Oxide is a rare earth oxide compound, which is a basic anhydride and can react with acids and with potent reducing agents in redox reactions. Rare earth oxide compounds contain at least one oxygen anion and one metallic cation. They are typically insoluble in aqueous solutions (water) and extremely stable, which makes them useful in ceramic structures. For this reason, Praseodymium Oxide has a wide range of applications, from producing clay bowls to advanced electronics. Praseodymium Oxide is also valuable for lightweight structural components in aerospace and electrochemical applications such as fuel cells due to its ionic conductivity.

Chemische Eigenschaften

dark green to dark brown or black powder.
Praseodymium oxide is a weak coloring oxide that melts at (1710°F)932°C. One of the lanthanide oxides, praseodymium is classified in the periodic table as a rare earth oxide. It's not used extensively in ceramics but is used in yellow stains with zirconium silicate. This oxide is slightly soluble in water and is very toxic.
Praseodymium oxide
Praseodymium can be obtained as an oxide but it's usually introduced into a glaze recipe in the form of a commercial stain such as Mason 6433,6405, or 6407.

Verwenden

Used in ceramic structures. Have a wide range of applications from producing clay bowls to advanced electronics. Praseodymium oxide is also useful in light weight structural components in aerospace and electrochemical applications such as fuel cells due to its ionic conductivity. Component of didymium glass which is a colorant for welder's goggles, also as important additive of Praseodymium yellow pigments.

Application

Praseodymium oxide nanoparticle is widely used in magnetic materials. It has also applications in catalysis.

l?uterung methode

Dissolve the oxide in acid (perchloric acid), precipitate it as the oxalate and the salt is ignited at 650o to give the oxide.
