Application:

For construction ceramics and ceramics for daily use, which blend with the ceramic enamel glaze, but also can be used alone as underglaze pigment used to make permanent magnets. The magnets can be processed into various shapes. Widely used in various types of electronic devices and motor; for petroleum cracking. Praseodymium neodymium enrichment in the form of added oil cracking catalyst Y-type zeolite molecular sieves, can increase the activity, selectivity and stability of the catalyst; for abrasive polishing; also for fiber optic fields.

Packing:

50KGS per Bag,PVC bag for inner packing,weaving bag for outer packing.
