Recently, the glass scientists of many countries have showed great interest in oxynitride glasses. They have measured some properties in MAlSiON or MSiON system glasses (MMg, Ca, Y, La etc.) It was suggested that the nitrogen

The influence of phase separation and crystallization on the internal friction of some oxide glasses is reviewed and discussed. In alkali-containing glasses, the internal friction peak caused by stress-induced diffusion of alkali ions decreases in ma
