Glass-formation in sodium-phosphate system is studied. The effect of potassium and lithium oxide on the crystallization in Na2O-P2O5 glasses is studied. Compositions of 55P2O5-(45-x)Na2O-xK2O; (5 ≤ x ≤ 25) and 55P2O5-(45-x)Na2O-xLi2O; (5 ≤ x ≤ 25) are synthesized by melt-quench method. Prepared samples are characterized by X-ray diffraction to confirm their glassy nature. DTA is used to find out their glass transition and crystallization temperatures. With the help of Kissinger’s and Augis-Benett models, crystallization kinetics for all glasses is studied. In all samples, 15 mol % Li2O, 10 mol % K2O and 20 mol % K2O glasses shows better kinetic and thermodynamic stability. FTIR and Raman study supported the above results. The electrical conductivity observed for 15 mol % Li2O, 10 mol % K2O and 20 mol % K2O glasses are 3×10-5, 2 ×10-6 and 4×10-6 S/cm, respectively. These samples can be used as solid electrolyte for solid sate batteries at room temperature.
