Praseodymium (III, IV) Oxide
Praseodymium (III, IV) Oxideyog cov tshuaj inorganic nrog cov mis Pr6O11 uas tsis yaj hauv dej. Nws muaj cov qauv cubic fluorite. Nws yog daim ntawv ruaj khov tshaj plaws ntawm praseodymium oxide ntawm qhov kub thiab txias thiab siab. Nws yog qhov tsis yaj hauv thermally ruaj khov Praseodymium qhov chaw tsim nyog rau iav, optic thiab ceramic daim ntawv thov. Praseodymium (III, IV) Oxide feem ntau yog High Purity (99.999%) Praseodymium (III, IV) Oxide (Pr2O3) Hmoov tsis ntev los no muaj nyob rau hauv feem ntau ntim. Ultra high purity thiab high purity compositions txhim kho ob qho tib si optical zoo thiab usefulness raws li cov qauv kev tshawb fawb. Nanoscale elemental hmoov thiab suspensions, raws li lwm cov ntaub ntawv siab deg, yuav raug txiav txim siab.
