Abstract A melting--thermodynamic model is developed, which can describe the
effect of size and shape of metallic nanoparticle on its
melting--thermodynamic properties. It is predicted that there exist
a minimum critical size
and a lowest melting temperature
for
metallic nanoparticle. The present theoretical results on the melting
point, the melting entrapy and the melting enthalpy of nanoparticles
Au, In, Al and Sn are consistent with the corresponding experimental
values.
