| 總結: | Variations in size distributions of particles and aggregates upon dilution of kerosene-based magnetic fluids have been studied by dynamic light scattering. The data obtained on samples of magnetic fluids produced by three different manufacturers have shown that the dilution of an initial concentrated magnetic fluid leads to the formation of a system of unstable aggregates with sizes ranging from 70−100 nm to 1 μm. The aggregates peptize for 2−4 days to result in the establishment of stationary particle and aggregate size distributions |
