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.
