What is Praseodymium oxide?
Chemical properties
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 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.
The Uses of Praseodymium oxide
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.
The Uses of Praseodymium oxide
Glass and ceramic pigment, laboratory reagent.
The Uses of Praseodymium oxide
This compound is a yellow powder used to color glass and ceramics.
What are the applications of Application
Praseodymium oxide nanoparticle is widely used in magnetic materials. It has also applications in catalysis.
Flammability and Explosibility
Non flammable
Purification Methods
Dissolve the oxide in acid (perchloric acid), precipitate it as the oxalate and the salt is ignited at 650o to give the oxide.
