Measurements of size increment for Ag smoke particles against the temperature has shown that the coalescence of Agsmokes takes place at 270℃. High resolution electron microscopy of the boundary between connected particles hasshown that the particles are connected in either a (111) twin relation or (100) parallel orientation. The parallel orientationis predominantly seen in the temperature ranges of 270〜400℃. By using the Lindeman melting formula and reported Debye temperature, it is shown that the coalescence phenomena in smoke particles can be explained by taking into ac-count the two processes with the temperature, i.e. the liquid-like coalescence and surface melting coalescence.
