| Hazard Information | Back Directory | [Chemical Properties]
yellow-green amorphous; 3–12mm pieces with 10μm average or less with 99.9% purity [CER91] [CRC10] | [Uses]
Praseodymium(III) oxide is used as a pigment in glass, optic and ceramic industries. Praseodymium-doped glass called didymium glass is used in welding goggles, since it blocks infra-red radiation. Further, it is used as a dielectric in combination with silicon. | [Flammability and Explosibility]
