Abstract
Abstract Sodium pyrophosphate Na4P2O7 has been studied by several methods: complex impedance spectroscopy (IS) measurements, at variable temperature, have given the variation of conductivity with temperature. This method is supplemented by thermal analysis. The results are correlated with the different phase transitions and activation energies are calculated for each phase.
