Raman thresholds and rigid to floppy transitions in calcium silicate glasses

M. Micoulaut, M. Malki, P. Simon +1

Alkaline earth silicate glasses $x C a O - (1 - x) S i O_{2}$ exhibit a well marked threshold in Raman lineshapes which can be related to the onset of network rigidity as the concentration of…

Percolative conductivity in alkaline earth silicate melts and glasses

M. Malki, M. Micoulaut, F. Chaimbault +2

Ion conducting $(C a O)_{x} (S i O_{2})_{1 - x}$ glasses and melts show a threshold behaviour in dc conductivity near $x = x_{t} = 0.50$ , with conductivities increasing linearly at $x > x_{t}$ . We show…
