This paper describes the results of the determination of some thermal and structural parameters of glasses from the Cu_{x}(As_2Se_3)_{100-x} system for x=0, 1, 5, 10 and 15 at.%. Based on the differential scanning calorimetry curves taken at different heating rates, glass transition temperature T_{g}, onset temperature of crystallization T_{onset}, and melting temperature T_{m} of crystalline units formed are determined. The values of activation energy E_{g} of glass transition process are calculated. These characteristic temperatures served as the basis for the calculation of the parameters of thermal stability of the glasses towards crystallization.
