✦ Synopsis

It is studied the effect of the preliminary heat treatment on the kinetics of nucleation by the numerical computation of the kinetic equations of the classical homogeneous nucleation theory for the model Li,O. 2Si0, melt. It was shown, that we can obtain some unexpected results, e.g., the time dependence of the nucleation rate exhibits the jump depending on the preliminary heat treatment.
