Praseodymium(III,IV) Oxide

Praseodymium (III,IV) Oxide is the inorganic compound with the formula Pr6O11 that is insoluble in water. It has a cubic fluorite structure. It is the most stable form of praseodymium oxide at ambient temperature and pressure.It is a highly insoluble thermally stable Praseodymium source suitable for glass, optic and ceramic applications. Praseodymium(III,IV) Oxide is generally High Purity (99.999%) Praseodymium(III,IV) Oxide (Pr2O3) Powder lately available in most volumes. Ultra high purity and high purity compositions improve both optical quality and usefulness as scientific standards. Nanoscale elemental powders and suspensions, as alternative high surface area forms, may be considered.

What is Praseodymium (III,IV) Oxide used for?

Praseodymium (III,IV) Oxide has a number of potential applications in chemical catalysis, and is often used in conjunction with a promoter such as sodium or gold to improve its catalytic performance.

Praseodymium(III, IV) oxide is used in pigment in glass, optic and ceramic industries. Praseodymium-doped glass, called didymium glass is used in welding, blacksmithing, and glass-blowing goggles due to its blocking property of infrared radiation. It is employed in the solid state synthesis of praseodymium molybdenum oxide, which is used as a semiconductor.
