The glass-forming ability explained from local structural differences by NMR between glasses and crystals in alkali metaphosphates

[EN] The glass forming ability of inorganic substances has traditionally been evaluated in kinetic terms related to the rate of spontaneous crystallization of their melts, which is related to viscosity from the macroscopic point of view. However, differences or similarities between the local structu...
