  Crystallization kinetics has features that are universal and independent of
the type of crystallized system. The possibility of using scaling relations to
describe the temperature dependences of the surface self-diffusion coefficient
$D_s$, which is one of the key characteristics of crystallization kinetics, has
been demonstrated in application to various crystallized molecular glasses. It
has been shown that the surface self-diffusion coefficient $D_s$ as a function
of the dimensionless temperature is reproduced by a power law and is
universally scaled for all considered systems. The analysis of experimental
data has revealed a correlation between the crystallization kinetic
characteristics, index of fragility, and criterion of the glass-forming ability
of a liquid. It has been shown that this correlation can be obtained within the
generalized Einstein-Stokes relation.
