Mixed crystals of the Nasicon composition Na1+xZr2SixP3−xO120.4⩽x⩽2.8 cannot be prepared as pure monophases because free ZrO2 always occurs as an impurity. In this paper a new solid solution is presented which is defined by the end compounds NaZr2P3O12 and Na4ZrSi3O10. Mixed ...
For the purpose of a precise evaluation of the electrochemical values the specific heats of ZrP 2O 7 and Na 2ZrSi 2O 7 have also been determined. A thermodynamic mixture model is constructed showing that the solid solution is entropy stabilized. The energetic interaction has a destabilizing ...
