Abstract

The process of secondary nucleation and the subsequent crystal growth process have been investigated both by fast-dynamic light scattering method and optical microscop under the micro gravity in drop shaft. It was found that the movement of crystals formed in solution could be suppressed completely in micro gravity, in which collision and agglomeration phenomena did not take place. No nucleation occured except for the seed crystal surface. Also it could be measured the number and size of produced crystals with order of nano-meter by fast-dynamic light scattering method.
