Praseodymium Oxide (Pr₆O₁₁): Ceramic Pigments, NdFeB Magnets, Oil Catalysts, Polishing, Fiber Optics

Praseodymium oxide is an inorganic compound with the chemical formula Pr₆O₁₁, appearing as black powder with a density of 6.5g/cm³, melting point of 2500°C, and boiling point of 3760°C. It is insoluble in water but soluble in acid to form trivalent salts. Under conditions of 1500°C temperature and 15MPa pressure, praseodymium oxide can be reduced by hydrogen to form praseodymium(III) oxide. Its properties make it suitable for polishing materials, catalysts, catalyst carriers (additives), glazes, fuel cell electrolytes, automotive exhaust absorbers, and electronic ceramics.

Applications

1. Used in architectural ceramics and daily-use ceramics. When mixed with ceramic glaze, it produces colored glaze, and can also be used alone as underglaze pigment, producing a pure and elegant light yellow tone.
2. Used in manufacturing permanent magnets. Using affordable praseodymium-neodymium metal instead of pure neodymium metal to produce permanent magnetic materials significantly improves oxidation resistance and mechanical properties, and can be processed into magnets of various shapes. Widely used in various electronic devices and motors.
3. Used in petroleum catalytic cracking. When added to Y-type zeolite molecular sieves in the form of praseodymium-neodymium concentrate to prepare petroleum cracking catalysts, it improves the catalyst's activity, selectivity and stability.
4. Used for abrasive polishing.
5. Also used in optical fiber applications.

About Praseodymium Oxide
The main production method for praseodymium oxide is the oxalate precipitation method. Using praseodymium chloride or praseodymium nitrate solution as raw material, adjust pH to 2 with oxalic acid, then add ammonia water to precipitate praseodymium oxalate. After heating and aging, separate and wash the precipitate, dry at 110°C, then calcine at 900-1000°C to form praseodymium oxide.
