## Abstract

Tellurium-based glasses find application as electrical switching devices [1]. The formation of a crystalline filament between the electrodes has been observed in memory-type switching glasses after being switched to the conducting state from the high-resist-ance state [2]. This has led to the suggestion that the crystallization of these glasses could possibly be the mechanism behind the irreversible switching action observed in these materials. An understanding of the crystallization kinetics of these glasses is important in this respect. The thermal crystallization behaviour of Si-As-Te has not been well investigated. In this letter differential scanning calorimetry studies on $Si_{l0}As_xTe_{90_ x}$ $(10\leq x \leq50)$ and $Si_{15}AS_x-Te_{85-x}$ $(5\leq x \leq45)$ glasses are reported.
