Gadolinium Ferroalloy Gadolinium Iron Alloy GdFe For Magneto-optical Recording Material
product detail
Name: Gadolinium Iron Alloy Molecular formula: GdFe
Size: according to user's requirements Gd content: 69%, 72%, 75%(wt)
Description: Gadolinium iron alloy is used to replace gadolinium in NdFeB, which can improve the yield of NdFeB and reduce the cost of NdFeB. In general, gadolinium iron alloy is prepared by industrial scale electrolysis with GdF3-LiF binary system as electrolyte, pure iron as cathode, graphite as anode and gadolinium oxide as raw material.
