The application of NASICON (Na 2Zr 2Si 2PO 12) to the thermodynamic study of beta-alumina
The solid-state galvanic cell with NASICON as an auxiliary electrolyte was built. The standard free enthalpy, entropy and enthalpy of beta-alumina formation as well as the Na 2O-activity in the alpha-alumina—beta-alumina coexistence region were determined in the temperature range 970–1220 K. The lim...

| Zusammenfassung: | The solid-state galvanic cell with NASICON as an auxiliary electrolyte was built. The standard free enthalpy, entropy and enthalpy of beta-alumina formation as well as the Na
2O-activity in the alpha-alumina—beta-alumina coexistence region were determined in the temperature range 970–1220 K. The limiting temperature of spontaneous decomposition of beta-alumina was also estimated. The results were compared with those obtained by other authors. |
