L. Gagoduport et al., NUCLEATION AND CLUSTERING - A MICROSCOPIC STUDY OF THE AGGREGATION BEHAVIOR IN METASTABLE SOLUTIONS, Journal of non-crystalline solids, 193, 1995, pp. 503-508
The aggregation state of metastable solutions has been studied by smal
l angle neutron scattering. The variation of the scattering curves was
monitored during continuous cooling for aqueous solutions of ND4Cl. T
he analysis of the data indicates the existence of finite-sized domain
s responsible for the variation of the scattering density on undercool
ing. The data have been analyzed using a Percus-Yevick hard-sphere mod
el which gives cluster sizes between 10 and 30 nm with an average inte
rparticle distance of 100-200 nm.
