In the present study, as a fundamental study for recycling Nd from Nd-Fe-B permanent magnet scrap, electrochemical Nd-alloying behavior of Fe was investigated in molten LiF-CaF 2 -NdF 3 (0.3 or 0.5 mol%) system at 1123 K. Herein, equilibrium potential 3+ /Nd determined 0.18 V (vs Li + /Li) by open-circuit potentiometry using Mo electrode. Cyclic voltammetry and were conducted an electrode, resu...

introduction: the aim of this study was to evaluate and compare the scanning electron microscope (sem) of indirect composite conditioned by erbium-doped yttrium aluminum garnet (er:yag) laser, neodymium-doped yttrium aluminium garnet (nd:yag) laserand carbon dioxide (co2) laser. methods: 18 indirect composite blocks (gc gradia da2, japan) with 15 × 10 × 10 mm dimensions were made. the bonding s...

The coercivity mechanism of Nd-Fe-B thin film samples with and without Nd deposition was investigated by simultaneous chemical and magnetic imaging by means of X-ray magnetic circular dichroism-photoemission electron microscopy. The two Nd-Fe-B thin film samples exhibited almost the same surface morphology and magnetic domain patterns, but their coercive fields were quite different, being 0.98 ...

Electrodeposition processes of neodymium and praseodymium in molten NdF3 + PrF3 LiF 1 wt.%Pr6O11 wt.%Nd2O3 2 electrolytes at 1323 K were investigated. Cyclic voltammetry, square wave open circuit potentiometry applied to study the electrochemical reduction Nd(III) Pr(III) ions on Mo W cathodes. It was established that a critical condition for Nd Pr co-deposition oxyfluoride constant deposition ...

Introduction: The coupled Sm-Nd systematics of lunar samples has been extensively studied for estimating the timescale of lunar differentiation [1-3]. The published datasets yield consistent ages for Nd isotopic closure within the lunar mantle of ~200 Myr after CAI formation. Although this time constraint is consistent with estimates derived from Hf-W chronometry of the Moon (>60 Myr after CAI ...
