  The aim of this work is to understand agglomeration of charged powders
suspended in nonpolar fluids. The concerted influence of electromagnetic,
hydrodynamic and van der Waals forces as well as Brownian motion leads to a
complex agglomeration behaviour which depends on several parameters, e.g., the
ratios of electric charges, particle sizes, temperature and concentrations of
the particles. Both experimental and theoretical considerations are presented.
