Coalescence Growth Mechanism of Smoke Particles

Chihiro Kaito

(Received December 14, 1983; accepted for publication December 15, 1984)

Measurements of size increment for Ag smoke particles against the temperature has shown that the coalescence of Ag smokes takes place at 270°C. High resolution electron microscopy of the boundary between connected particles has shown 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°C. 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 account the two processes with the temperature, i.e. the liquid-like coalescence and surface melting coalescence.
