Nuclear magnetic resonance analysis and activation energy spectrum of the irreversible structural relaxation of amorphous zirconium tungstate

Zirconium tungstate undergoes a sequence of phase transitions from cubic (α−ZrW2O8) to orthorhombic (γ−ZrW2O8) to amorphous (a−ZrW2O8) upon increasing pressure at room temperature. The amorphous phase is known to undergo anomalous endothermic recrystallization into a high-temperature β−ZrW2O8 phase...
