At a glance


The aim of the project was the development of synthesis and processes routes for the production of spherical, mechanically and chemically stable monomodal ceramic particles with controlled porosity for the use as chromatography materials.

The targeted properties were:

  • Chemical stability against high and low pH
  • High mecanical stability (ceramic)
  • Narrow particle size distribution
  • High specific surface
  • Defined pore sizes
  • Taylored surface functionalization, examples of materials of interest were e.g. ZrO2, TiO2, CeO2 or Al2O3.
