Praseodymium Oxide CAS 12037-29-5

Black powder, density 6.88g/cm3, melting point 2042 ℃, boiling point 3760 ℃. Insoluble in water, soluble in acid to form trivalent salts. Good conductivity. It is used in building ceramics and daily ceramics. It can be mixed with ceramic glaze to make colored glaze, or used as underglaze pigment alone. The pigment is light yellow, pure and elegant in color, and used to make permanent magnet. Using low-cost praseodymium neodymium metal to replace Pure Neodymium metal to make permanent magnet material, its oxygen resistance and mechanical properties are obviously improved, and it can be processed into various shapes of magnets. Widely used in all kinds of electronic devices and motors; used in oil catalytic cracking. Adding praseodymium and neodymium to Y zeolite can improve the activity, selectivity and stability of catalyst, be used in abrasive polishing, and be used in optical fiber field.
