Summary, etc. Alloys of Se<sub>100-x</sub>Sb<sub>10-x</sub>Ag<sub>x</sub> (x=2, 4 &amp;8) glassy system have been obtained by quenching technique. Kinetic parameters, which represent thermal stability, have been determined from differential scanning calorimetric technique. The rate of crystallization decreases with Ag concentration and is lowest for glassy Se<sub>90</sub>Sb<sub>2</sub>Ag<sub>8</sub> alloy. Thermal stability (<em>T</em><sub>c</sub>-<em>T</em><sub>g</sub>), Hruby criterion <em>H</em><sub>r </sub>, Saad Poulain ‘<em>S</em>’ have been found to increase with Ag concentration and are maximum for Se<sub>90</sub>Sb<sub>2</sub>Ag<sub>8</sub>. Thus, one can conclude that the rate of crystallization is related to the thermal stability. The reduced glass transition temperature for Se<sub>90</sub>Sb<sub>10-x</sub>Ag<sub>x</sub> is found to be 2/3, which shows that these glassy alloys are suitable for phase change optical memories.
