Praseodymium oxide is a black powder, Insoluble in water, soluble in acid to generate trivalent salts. Good electrical conductivity.


Used in building ceramics and ceramics for daily use, its mixed with ceramic glaze glaze, also can make the glaze pigment alone, made of pigment with pale yellow, color pure, quietly elegant; Used in the manufacture of permanent magnets. Choose cheap praseodymium neodymium metal instead of pure metal manufacturing neodymium permanent magnet materials, the antioxidant properties and mechanical properties, can be processed into various shapes of magnets. Widely used in all kinds of electronic device and the motor; Used in oil catalytic cracking. In the form of richment neodymium praseodymium in Y type zeolite molecular sieve preparation of oil cracking catalyst, can improve the catalyst activity, selectivity and stability; Used for abrasive polishing. Also used for the field of optical fiber, etc.

Package;50 kg/drum, inner double plastic bag; Or 50 kg/bag, double plastic bag; Can also according to customer requirements packaging.
