This work presents the use of molecular dynamics (MD) and the code of
Dl_Poly, in order to study the structure of fluoride glass after melting
and quenching. We are realized the processing phase liquid-phase, simulating
rapid quenching at different speeds to see the effect of quenching rate on
the operation of the devitrification. This technique of simulation has
become a powerful tool for investigating the microscopic behaviour of matter
as well as for calculating macroscopic observable quantities. As basic
results, we calculated the interatomic distance, angles and statistics,
which help us to know the geometric form and the structure of PbF2.
These results are in experimental agreement to those reported in literature.
