X-Ray Analytical Spectroscopy of the Rare Earths

Description: Technical report. From Abstract : "The term 'rare earths' is the classic name given to the group of elements with atomic numbers 57 to 71. The element yttrium is usually included in this group. The chemical properties of these elements are so strikingly similar that they always occur together in nature and their separation from each other is a singularly difficult task. With but few exceptions, mixtures of these elements have also defied analysis by classical methods of analytical chemistry. Co… more

Boiling Points and Surface Tensions of Mixtures of Benzyl Acetate With Dioxan, Aniline and Meta-Cresol

Description: Technical report. From Abstract : "Accurate measurements on boiling points and surface tensions of mixtures of benzyl acetate with dioxan, aniline and meta-cresol over the entire range of concentration are reported. The results have been analysed in terms of quasi-crystalline model which is partially successful in representing the composition dependence of heats of mixing, boiling points and surface tension except for composition dependence of boiling points of benzyl acetate and meta-cresol."

I. Niobium(IV) Bromide and Pyridine Adducts of the Niobium(IV) Halides

Description: Technical report. From Abstract : "Reaction of NbBr5 and niobium metal in a sealed tube under a temperature gradient from 410° to 350° gave NbBr4 in good yields. However, an increase in the higher temperature from 410° to 450° was sufficient to eliminate NbBr4 as a product and cause deposition of a lower bromide."

Magnetic Properties of Some Intra-Rare Earth Alloys

Description: Technical report. From Abstract : "Paramagnetic susceptibilities of samarium structure alloys in the systems La-Gd, Nd-Y, Nd-Tm, and Ce-Y were measured from 4.2 - 300°K to determine what effect the formation of this structure has on the magnetic properties of the alloys. Susceptibility maxima were observed in the Nd-Y and Nd-Tm alloys, at 34.5 and 28.5°K, respectively. Slope changes were observed in the curve of 1/x versus T for the La-Gd alloy at 155 and 130°K, and the susceptibility of this a… more

Rare Earth Metal - Metal Halide Systems, Lanthanum, Cerium, and Praseodymium Bromides

Description: Technical report. From Abstract : "The MBr3 + M phase diagrams for lanthanum, cerium, and praseodymium are presented. Lanthanum and cerium exhibit simple solutions of metal, with 14 and 12 mole % dissolved at eutectic temperatures of 728 and 687°, respectively. The compound PrBr2.38 is found, melting incongruently to a solution of 16% Pr in PRBr3 and Pr(s) at 601°. For praseodymium the cryoscopic behavior of dilute solutions of metal is consistent with the primary formation of the Pr2+ solute. … more
