The results of studying the kinetics of non-isothermic crystallization of Sb-S-I glasses are given. By DTA and DerTA methods the characteristic temperatures of thermal effects $T_g$, $T_c$, $T_m$ have been investigated. The activation energies of originating nuclei of crystals $Δ G_{A0}$ and their growth $Δ G_{AM}$ have been calculated from temperatures begining at $T_{C0}$ and maximum $T_{CM}$ of the crystallization effect as a function of the heating rate $q$. The critical radii for nuclei of crystals $r_c$ and amorphization radii $r_a$ are calculated. The crystallizability of melts depending on the composition has been studied. The compositions from the regions of eutectics have been shown to possess a minimal crystallizability, and those ones in the vicinity of $\mbox{Sb}_2\mbox{S}_3$ and SbSI stoichiometric compounds possess a maximal one. The results obtained are being discussed proceeding from the peculiarities of the structure of studied materials.
