摘要：

Small angle neutron scattering has been used to examine calcium carbonate dispersions in toluene over the w/w concentration range 5 to 40%. The particles were stabilized by a combination of a surface active agent and a linear polymeric molecule. Analysis of the experimental data gave results for the structure factor and the pair correlation function. Theoretical computations of the structure factor were made using a hard sphere model and the mean spherical approximation approach. These analyses indicated that the interaction was essentially soft at low volume fractions but became hard at the higher volume fractions.
