The crystallization kinetics of bulk Se(90-x)Te(5)Sn(5)In(x) (x=0, 3, 6 and 9) multi-component chalcogenide glasses have been studied using differential scanning calorimetry (DSC) with heating rates 5, 10,15 and 20 K/min under non-isothermal conditions. Values of various kinetic parameters of crystallization, such as onset crystallization temperature (T(c)), peak crystallization temperature (T(p)), activation energy of crystallization (E(c)), rate constant (K(p)), Hruby number (K(gl)) and the order parameter (n) have been determined. It was found that activation energy of crystallization and rate constant (K(p)) are minimum at 9 at% In. On the basis of the obtained experimental data t
