Pentacoordinated silicon in ambient pressure potassium and lithium silicate glasses: Temperature and compositional effects and analogies to alkali borate and germanate systems

Pentacoordinated silicon (SiO5) has long been considered as a possible reactive intermediate in bond-swapping reactions in even ambient pressure viscous flow, diffusion, nucleation and crystallization. In this paper, new results are presented for potassium silicate glasses and for two lithium silica...
