The results of non-isothermal crystallization studies performed at different heating rates on batches of As2Se3 glasses prepared iron melts at 4oo'C. 6oo'C and 800'C13; are reported. The peak temperature of crystallization T, the enthalpy of crystallization AH,and the activation energy for crystallization E. are independent of the melt temperature used in the preparation. Bulk nucleation with three-dimensional growth of crystals is indicated for As2Se3. The values of AH6 and E6 are found to be respectively 23.3=09cal/g and 36.5=09 keal/mol for As2Se3.
