Application fields:

Used in construction ceramics and ceramics for daily use, and the ceramic glaze made of mixed glaze, can also be separately under glaze pigment, the pigment is made of pale yellow, color pure, elegant; used in the manufacture of permanent magnet. Selection of cheap praseodymium neodymium metal instead of Pure Neodymium metal manufacturing permanent magnetic material, its antioxidant properties and mechanical properties are obviously improved, can be processed into various shapes of magnet. Widely used in various types of electronic devices and motors; used for catalytic cracking of petroleum. Praseodymium neodymium concentrates to join the Y type zeolite molecular sieve preparation of petroleum cracking catalyst, the catalyst can improve the activity, selectivity and stability; used for abrasive polishing; also used for optical field.
