  New Complex Phosphate Cation-Conducting Materials in Ternary System Li3PO4-Na3PO4-InPO4

  摘要：

  Phase equilibrium in ternary system Li3PO4-Na3PO4-InPO4 and formation of heterovalent Zr-substituted solid solutions (up to 15 mol%) for In3+ in Li3In2(PO4)(3) and Na3In2(PO4)(3) complex phosphates were studied by the cross-section method at 950 degrees C. Samples obtained were investigated by X-ray powder diffraction and impedance spectroscopy. Ionic conductivity of Na3In2(PO4)(3) and Li3In2(PO4)(3) complex phosphates is about 10(-2) S/cm at 300 degrees C. Heterovalent substitution was performed according to the scheme: In3+ = Zr4+ + v, where v is a vacancy in cationic sublattice. Zr-substituted (15 mol%) Na3In2(PO4)(3) and Li3In2(PO4)(3) have ionic conductivity of about 10(-1) S/cm at 300 degrees C.

  concerned with the ionic conductivity of pure trisodium orthophosphate Na3PO4, devoid of any trace of hydroxide NaOH. At the allotropic transition (330°C), we observe a jump of the ionic conductivity and a slight decrease in the activation energy (ΔE = 0,70 ± 0,02 eV for the quadratic variety and ΔE = 0,60 ± 0,04 eV for cubic γ-Na3PO4). Na3PO4 can be considered to be an electrolytic solid with medium conductivity

  was conducted of pure Na3PO4 and solid solutions of Na3PO4 doped with Mg2+ and Zn2+. Na3PO4 has two solid phases: a low-temperature tetragonal phase and a high-temperature cubic phase. A factor group analysis of the two phases yielded the expected number of modes and their symmetry-based assignments. A temperature-dependent Raman spectroscopic study was then performed for the pure compound. Analysis

• Investigation of the basis of catalytic activity of solid state phosphate complexes in the Knoevenagel condensation

  The Knoevenagel condensation of benzaldehyde and ethyl cyanoacetate in ethanol at ambient temperature was catalyzed with range of mono-, meta- and diphosphate complexes. Comparison of the results shows that the catalytic activity of those phosphates is related to the electropositivity of the cation present in the structure and to the availability of the phosphate moiety to serve as a base.
