Particle Technology Demonstrations for the Classroom and Laboratory


  • Simon I. Iveson University of Newcastle
  • George V. Franks University of Newcastle


There are many simple but illustrative experiments that can be used to demonstrate the often counter-intuitive behavior of powder systems when compared to gas and liquid systems, but reference to them is scattered haphazardly throughout the literature. This is a compilation of such demonstrations, both from the literature and of our own devising. Topics covered include sedimentation, flocculation, hindered settling, hopper flow, flow and vibrational segregation, powder dilation, wall friction, and surface chemistry effects. The examples provide at least one demonstration for each lecture of a one-semester introductory course on particle technology.

Author Biographies

Simon I. Iveson, University of Newcastle

Simon Iveson completed his Bachelor of Chemical Engineering in 1992 and his PhD in 1997, both at the University of Queensland. Since then he has been a research fellow and lecturer in the Department of Chemical Engineering at the University of Newcastle. His research interests are in the field of particle technology, with his focus being on the agglomeration of fine particles by the addition of liquid binders.

George V. Franks, University of Newcastle

George Franks completed his BS in Materials Science and Engineering at MIT in 1985 and his PhD in Materials at the University of California at Santa Barbara in 1997. He has been a senior lecturer in the Chemical Engineering Department at the University of Newcastle since 1999. His research interests include colloidal processing of ceramics, mechanical behavior of wet powder bodies, and mineral processing processes such as flocculation.
