Differential scanning calorimetric (DSC) studies have been carried out in an attempt to explain the composition dependence of the thermal crystallization behaviour of $Cu_xGe_{15}Te_{85-x}$ glasses. It is seen that these glasses exhibit a single glass transition and single stage crystallization on heating. The glass transition temperature, crystallization temperature and the activation energy for crystallization are each found to exhibit an anomaly at around the composition x = 5. The anomalies observed in the thermal properties at x = 5 can be associated with rigidity percolation.
