The temperature regions for separate crystallization of rare-earth element (REE) oxides of the cerium group in the presence of CaCO3 have been determined using X-ray diffraction, differential thermogravimetric analysis, inductively coupled plasma mass spectroscopy, and X-ray fluorescence. The possibility to separate REE oxides from CaCO3 in H2SO4 s...

Nb2O5〈В〉 solid precursors and LiNbO3〈В〉 batches prepared on their basis, which can be used for preparing optical-quality lithium niobate single crystals and pore-free piezoelectric ceramics, have been studied by laser ablation inductively coupled mass spectrometry (LA-ICP-MS). The compositions of powdery samples pelletized without binder have been ...

Subsolidus phase ratios in K2MoO4–CaMoO4–Ln2(MoO4)3 systems where Ln = Nd, Sm, Eu, and Gd, have been studied by vibrational spectroscopy, X-ray powder diffraction, and differential thermal analysis. Triple molybdates KCaLn(MoO4)3 (Ln = Nd, Sm, Eu, and Gd) have been synthesized; they have a scheelite-derivative structure, monoclinic crystal system (...

The mutual effect of the components in four aqueous systems consisting of sodium dicarbamidochlorate, monoethanolamine acetate, ethanol, and acetamiprid are studied. No new compounds are formed in these systems. The components of the systems upon joint presence retain their individuality. The results for the systems under study demonstrate that a l...

The solvothermal decomposition of a hybrid organic–inorganic material based on α-Со(ОН)2 and sodium dodecyl sulfate has been studied in n-octanol at 190°C and the atmospheric pressure. It has been found that the process includes two stages: in the first stage, anhydrous CoCO3 is formed, followed by its topochemical decomposition to form Co3O4. It h...

The successive elimination of H2 from Mg(BH4)2 · nH2O (n = 1, 4, 6), (Mg(BH4)2)2 · 8H2O, and (Mg(BH4)2)4 · 4H2O complexes has been modeled in the framework of the cluster approach with the use of the 6-31G* basis set and hybrid density functional (B3LYP). It has been shown that the structures in which the proton-donating water molecule is located b...

Chelating ligands based on polydentate diamides of 2,2'-bipyridyl-6,6'-dicarboxylic acid with a high affinity for lanthanide ions have been synthesized. The effect of the size of lipophilic aliphatic substituents in the ligand on the photophysical characteristics of europium complexes in acetonitrile solutions and in the solid state, as well as on ...

Phase equilibria in the ternary systems NaHal–NaVO3–Na2CrO4 (Hal = Cl, Br) were studied. By differential thermal analysis, eutectic alloys were found at points with coordinates (14.0 mol % NaCl, 66.5 mol % NaVO3, 19.5 mol % Na2CrO4, 530°C) and (27.0 mol % NaBr, 47.5 mol % NaVO3, 25.5 mol % Na2CrO4, 499°C). By differential scanning calorimetry, the ...
