Extension of α-AgI stabilization range in AgI-Ag2O-MxOy systems by mechanosynthesis processing

The ultra-fast quenching method and mechanosynthesis processing were employed to prepare the AgI-Ag2O-MxOy glasses (where MxOy = B2O3, WO3, MoO3, V2O5) containing AgI crystalline inclusions. After heating in elevated temperatures the α-AgI superionic phase was formed: regarding the composition and preparation method its stabilization to lower temperatures was investigated. X-ray diffraction, differential scanning calorimetry and scanning electron microscope methods were used. The study showed that employment of both methods outrivals the solely applied ultra-fast quenching or mechanosynthesis methods, giving the final product with a wider α-AgI stability range.
