CHARACTERISTIC RATE OF COOLING AND GLASSING OF LIQUIDS
The work is devoted to the analysis and generalization of kinetic criteria for glass transition using the model of delocalized atoms. A generalized criterion for the liquid-glass transition is proposed. A liquid transforms into a frozen glassy state when its cooling rate <i>q</i> = <i>dT</i>/<i>dt</i> reaches a certain fraction of <i>C<sub>g</sub></i> of the characteristic cooling rate <i>q<sub>g</sub></i> = <i>T<sub>g</sub></i>/τ<sub><i>g</i></sub>, which is closely related to the relaxation time of the structure tan at the glass transition temperature <i>T<sub>g</sub></i>.
