The alpha - beta phase transitions of Zn2P2O7 revisited: existence of an additional intermediate phase with an incommensurately modulated structure
Original language description
Zn2P2O7 crystallizes in a thortveitite-like structure and features temperature-dependent polymorphism. At high temperatures (T > 500 K), the aristotype phase beta-Zn2P2O7 is stable. At lower temperatures the lock-in phase alpha1-Zn2P2O7, a sixfold superstructure with commensurate modulation vector q = (1/3, 0, 1/2), is stable. Between the stability ranges exists the intermediate, incommensurately modulated alpha2-Zn2P2O7 phase with modulation wavevector q (0.33, 0, 0.40). The phase transitions were analyzed with differential scanning calorimetry and high-temperature powder and single-crystal X- ray diffraction. Different models describing the slow transition from the incommensurately modulated alpha2- to the non-modulated beta-phase were investigated.
