Abstract :
A molecular dynamic model of the properties of a strongly interacting particulate dispersion is described. The particles concerned are assumed to be acicular and the model is applied to the study of the properties of a dispersion of advanced metal particles for recording media. The model is applied to predictions of the magnetic behaviour of dispersions under shear, providing a basis for the understanding of shear magnetometry. The hydrodynamics of the dispersion are shown to be important as regards the microstructure of the final coated recording medium
