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

Abstract The ultra-fast quenching method and mechanosynthesis processing were employed to prepare the AgI–Ag 2 O–M x O y glasses (where M x O y = B 2 O 3 , WO 3 , MoO 3 , V 2 O 5 ) 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.
