Percolative conductivity in alkaline earth silicate melts and glasses

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

Ion conducting $(CaO{)}_x(Si{O}_2{)}_{1-x}$ 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…
