    Physicochemical properties of the EuBr2–KBr binary system
    摘要:
    The phase diagram of the EuBr2-KBr binary system was derived from DSC measurements. It exhibits three eutectics and three stoichiometric compounds. The first compound, K2EuBr4, melts congruently at 834 K. The second one, KEuBr3 undergoes a solid-solid phase transition at 810 K and decomposes peritectically at 846 K. The third compound, KEu2Br5, melts congruently at 880 K. The composition of the three eutectic mixtures, x(EuBr2) = 0.318, 0.433 and 0.789, respectively, were determined by the Tamman method. The respective eutectic temperatures are 829, 811 and 854 K.Diffuse reflectance spectra of the pure components and their solid inixtures confirmed the existence of new phases exhibiting their own spectral characteristics, which may be related to the existence of above mentioned compounds in the system under investigation.

    hydrated lanthanide bromides and N,N-dimethylacetamide (DMA) was studied. Compounds of general formula LnBr3·5DMA (Ln = La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, and Dy) and LnBr3·5DMA·3H2O (Ln = Ho, Er, Tm, Yb, Lu, and Y) were obtained. The i.r. spectra, the molar conductance of the compounds in DMA and nitromethane have been determined. A study considering the existence of cationic species in DMA solutions

At least part (about 30%) of the europium undergoes a valence change to europium(II) in the bromide system but not in the chloride system in the course of removal of water which occurs by dehydration and hydrolytic processes.

    摘要 研究了EuCl 3 ·6 H 2 O 和EuBr 3 · 6 H 2 O 在室温至900°C 温度范围内的热分解。所使用的技术是由化学分析、穆斯堡尔光谱、质谱和红外分光光度法支持的热重分析,适用于中间分解产物。当在缓慢的氮气流中加热时,会分阶段流失,这在化物系统中比在化物系统中更明确,分别高达 350°C 和 390°C,高于此温度,相应的氧化物卤化物是唯一主要的产品。在通过脱解过程除去的过程中,至少部分(约 30%)化物系统中发生化合价变化为(II),而在化物系统中则没有。因此,化物系统介于相应的化物和化物系统之间,因为后者似乎完全或接近完全转化为 (II)。氧化物化物和氧化物化物分别在 900 和 910°C 下转化为氧化铕 (III)。

    Abstract Complexes of rare earth bromides with glycine, REBr 3 ·3Gly·3H 2 O (RE is Ce, Pr, Sm, Eu, Gd, Tb, Dy and Y; Gly is glycine) have been synthesized and characterized by means of chemical analysis, elemental analysis, molar conductivity, thermogravimetry, IR spectra and X-ray diffractometry. The IR spectra of the above complexes indicate that in the complexes glycine is coordinated to rare earth
