• Abstract:

  Background
  Powder flowability is a crucial parameter for powder handling.
  Aims
  To investigate the influence of two different types of fumed silica on the flowability, wettability and surface free energy of a model cohesive powder.
  Methods
  Soda lime glass microspheres (VMD<4μm), the model cohesive powder, were dry coated with hydrophobic fumed..
