N2 - The glasses of two series Se(90-0.9x)S(10-0.1x)Asx and Se(60-0.6x)S(40-0.4x)Asx (where x varies from 0 to 15 at. % with a step of 2.5 at. %) are studied. It is revealed that, according to the DIN technique (German Industrial Standards), the glasses belong to the acid class I, hydrolytic class I, and alkali class III. The kinetic regularities of dissolution of chalcogenide glasses in alkaline solutions are determined under steady-state conditions without stirring. The quantitative dependences of the dissolution rate on temperature, concentration of alkaline solutions, and arsenic content in the glasses are obtained. The activation energies for dissolution are calculated.
