摘要
Na Sn2 (PO4)3 presents a fast and reversible second order phase transition about 575-degrees-C. Both phases above and below the transition point are rhombohedral. The high temperature phase is isostructural with Na Ti2 (PO4)3 and Na Zr2 (PO4)3, NZP structure. The lattice thermal expansion of these three compounds has been determined from x-ray diffraction data at different temperatures ranging from room temperature up to 1000-degrees-C. Differences in behaviour are discussed in relation to the structure.
