Abstract:  The phenomenon of electron irradiation induced quasi-fluid flow in solid amorphous silicates is examined. High-intensity electron beam irradiation of glass nanoparticles in TEM leads to a variety of transformations including rounding, bead formation, and phase separation. Evidence for possible rise in temperature, charging fields, and enhanced diffusion is collected and compared, while the latter effect (loosening of glass network) is shown to dominate.
