Nucleation and crystallization of an As2Se3 undercooled melt
Original language description
The isothermal nucleation of an As2Se3 undercooled melt followed by crystallization and consequent melting was measured by DSC using a constant heating rate. The melting enthalpy was used to quantify the degree of conversion, a. Nonlinear regression analysis of the dependence of conversion on isothermal nucleation temperature and time was performed on the basis of classical nucleation theory assuming normal 3D growth. The parameters for the temperature dependence of nucleation rate and growth rate weredetermined by a three step process. First the simple parabolic model was used to estimate the maximum and the width of rate-temperature curve. Then the obtained parabolic curves were fitted by theoretical ones. In the third step the parameters obtained in the previous steps were used for nonlinear regression analysis of the experimental data. The kinetic barrier of crystal growth was found to be in agreement with the activation energy for viscous flow.
