2014 The crystal field level scheme of RX3 (R = Ce, Pr, Nd ; X = In, Pb) intermetallic compounds has been determined by fitting susceptibility curves and specific heat Schottky anomalies ; an inelastic neutron diffraction experiment has been performed for NdIn3. The fourth order C. E. F. parameter A04 r4 > of the cérium compounds is positive ; it decreases for the praseodymium compounds an...

The effects of the neodymium content on creep properties and microstructures 9Cr-3Co-3W-Nd-B steel were investigated. Neodymium had a mild effect rupture strength at contents up to 0.056 mass%. This suggested that compounds solid-dissolved minimal in uniformly creep-deformed parts after normalizing tempering heat treatment. On other hand, reduction area was improved by addition neodymium. Creep...

The three component reaction of LnCp3, LnCp2Cl (Ln = Nd, Y) and N,N-bis[2-(pyrid-2yl)ethyl]hydroxylamine [HON(C2H4-o-py)2] results in the formation of the [Nd(ON(C2H4-opy)2)2]+[NdCp3Cl]− salt in the case of neodymium and the [Y(ON(C2H4-o-py)2)2]+[YCp2Cl2]− salt if yttrium is used in the synthesis. The N,N-bis[2-(pyrid-2-yl)ethyl]hydroxylaminato ligand is able to coordinate doubly to the metal a...

Cerium, neodymium and gadolinium contain double beta active isotopes. The most interesting are Nd and Gd (promising for 02 search), Ce (2 candidate with one of the highest Q2). The main problem of compounds containing lanthanide elements is their high radioactive contamination by uranium, radium, actinium and thorium. The new generation 2 experiments require development of methods for a de...

The syntheses and characterization of four new hybrid coordination networks based on lanthanide ions (Ln = Nd, Sm) and 1,3-carboxymethylimidazolium (L) salt in the presence of oxalic acid (H2ox) are reported. The influence of the synthesis parameters, such as the nature of the lanthanide ion (Nd3+ or Sm3+), the nature of the imidazolium source (chloride [H2L][Cl] or zwitterionic [HL] form) and ...

The electrodeposition of neodymium on a cobalt substrate in chloride-fluoride melt NaCl-KCl-10 wt.% NaF-5 NdF3 was studied. It is shown that during electrolysis, coating with crystal size 2-5 microns formed. Microanalysis the determined electrocrystallization intermetallic compounds Co17Nd2 and Co5Nd substrate.

In our study a new Fe-modified nano porous of MCM-41 was synthezied hydrothermally with cetyltrimethylammoniumbromide (C16TAB) as surfactant and charactrizied using XRD, SEM, FT-IR and BET. This work reports the adsorption of Neodymium from aqueous solution onto Fe-MCM-41.100 ml of stock solution of Neodymium was prepared.Various factors such as pH,the amount of adsorbent were considered. T...
