Abstract—The kinetics of stepwise transformations during bulk isothermal crystallization of semiconducting AsSe1.5Snx (х = 0.13, 0.20, 0.28) glasses has been studied in the temperature range of 210−310°С using 119Sn Mössbauer spectroscopy, XPA, and the density and microhardness measurements of the quenched specimens. The kinetics of the gross bulk crystallization of glasses have been analyzed according to the data on density measurement using the Kolmogorov–Avrami equation, which was generalized on stepwise and incomplete isothermal transformations.
Keywords: stepwise bulk thermal crystallization of glasses, cytalls, completion degree of crystallization, kinetic parameters of isothermal gross crystallization, 119Sn Mössbauer spectra, Kolmogorov–Avrami general equation
