英文摘要: A novel inorganic solid electrolyte with a layered framework structure stable up to 1043 K, Na-14.5[Al(PO4)(2)F-2](2.5)[Ti(PO4)(2)F-2](0.5)(NATP), has been hydrothermally prepared and characterized by single-crystal and powder X-ray diffraction techniques, X-ray fluorescence (XPF) analysis, IR spectroscopic measurement, thermogravimetric and differential thermal analysis (TGA and DTA). NATP crystallizes in the acentric hexagonal space group P3 with a = 10.448(2), b = 10.448(2), c = 6.589(3) angstrom, Z = 1, containing a large number of Na+ cations in the interlamellar space and the cavities of its framework. There are six different crystallographic Na+ cationic sites, in which 8% Na(5) and 12% Na(6) sites are vacant. Electrical conductivity measurements show that Na+ cations exhibit a high mobility with two domains for the electrical conductivity versus temperature. (c) 2006 Elsevier Ltd. All rights reserved.
