NASICON-related Na3.4Mn0.4Fe1.6(PO4)3
The solid solution, sodium [iron(III)/manganese(II)] tris-(orthophosphate), Na₃.₄Mn₀.₄Fe₁.₆(PO₄)₃, was obtained using a flux method. Its crystal structure is related to that of NASICON-type compounds. The [(Mn/Fe)₂(PO₄)₃] framework is built up from an (Mn/Fe)O₆octa-hedron (site symmetry 3.), with a mixed Mn/Fe occupancy, and a PO₄ tetra-hedron (site symmetry .2). The Na⁺ cations are distributed...
متن کاملNASICON-type Na3V2(PO4)3
Single crystals of the title compound, tris-odium divanadium(III) tris-(orthophosphate), were grown from a self-flux in the system Na(4)P(2)O(7)-NaVP(2)O(7). Na(3)V(2)(PO(4))(3) belongs to the family of NASICON-related structures and is built up from isolated [VO(6)] octa-hedra (3. symmetry) and [PO(4)] tetra-hedra (.2 symmetry) inter-linked via corners to establish the framework anion [V(2)(PO...
متن کاملNa NMR Study of NASICON - type Compounds ,
The structure of NASICON-type compounds, Nai+xScxTi2_z(P04)3 (0 < x < 2), and the dynamics of Na have been investigated by Na NMR spectroscopy. It was found that the Na ID and 2D MQMAS spectra depend on the Na concentration, suggesting strongly that the Na ions are distributed between two crystallographically nonequivalent sites, one is a special position with axial symmetry, and the other a po...
متن کاملRbSn2(PO4)3, a NASICON-type phosphate
The title compound, rubidium ditin(IV) tris-(phosphate), RbSn(2)(PO(4))(3), belongs to the NASICON-type family of phosphates and crystallizes in the space group R[Formula: see text]. The structure is composed of PO(4) tetra-hedra (1 symmetry) and two slightly distorted SnO(6) octa-hedra, both with 3. symmetry, which are inter-linked through corner-sharing O atoms to form a (3) (∞)[Sn(2)(PO(4))(...
متن کاملImproving NASICON Sinterability through Crystallization under High-Frequency Electrical Fields
The effect of high-frequency (HF) electric fields on the crystallization and sintering rates of a lithium aluminum germanium phosphate (LAGP) ion conducting ceramic was investigated. LAGP with the nominal composition Li1.5Al0.5Ge1.5(PO4)3 was crystallized and sintered, both conventionally and under effect of electrical field. Electrical field application, of 300 V/cm at 1 MHz, produced up to a ...
