Abstract

Melt quenched sulphide glass of system Na₂S-P₂S₅ has been synthesized by taking equimolar quantities of Na₂S and P₂S₅. The glass sample was characterized by XRD, DTA/TG, dilatometery and impedance spectroscopy. The XRD pattern of the sample showed a broad halo indicating its amorphous nature. The DTA curve showed different crystallization temperatures (T _c) at different heating rates. Crystallization kinetics of the synthesized sample was studied using Kissinger's model. The glass transition temperature of the present glass was lower than the silicate glasses. Based on DTA/TG results, the glass sample was heated at 400°C for 4 h to get the glass-ceramic composite. Room temperature conductivity of the glass-ceramic composite was observed to be 1.43 × 10^-5 S.cm^-1 with activation energy 28 kJ.mol^-1.
