Popis:	Static disorder of sodium ions appears ∼-20 K below the α ⤳ β superionic phase transition temperature in Na 3 Fe 2 (PO 4 ) 3 . This α ⤳ β transformation is first-order transition from the static to dynamic disorder in the sodium sublattice. It is caused by the strong sodium-sodium interactions but not the structural re-building of the [Fe 2 P 3 O 12 ] 3∞ 3− rigid skeleton.
