Isothermal evolution of phase composition, structural parameters, and ionic conductivity in Na1+xAlxGe2-x(PO4)3 glass-ceramics
Published in Journal of Non-Crystalline Solids, 2020
Longer heat treatment does not simply produce more of the same NASICON phase. In sodium aluminogermanophosphate glass-ceramics, extended annealing changes the aluminum content and produces additional crystalline and amorphous phases. Conductivity depends on this multiphase structure as well as on the composition of the principal ion-conducting phase.
