Particle Technology

Small and smallest particles are essential building-blocks for many advanced materials that are relevant in almost all fields of today’s technologies. Particles may be tailored to combine multiple functions or properties such as magnetism, electrical and thermal conductivity, luminescence, catalytic activity, or flame retardancy. When added to existing materials, small particles may significantly enhance their properties and so, ultimately, lead to brand-new applications.


Research topics include

  • Complex and multifunctional particles
  • Magnetic particles
  • Silica particles (such as MAGSILICA®)
  • Titanium, zirconium, zinc and perovskite oxide particles
  • Hollow particles/capsules
  • Core-shell particles
  • Layered particles
  • Fluorescent particles
  • Surface functionalized nanoparticles


Our equipment includes

  • 100 l stirring reactor (upscaling of laboratory syntheses up to the 100 liter scale)
  • Continuous ultrasound reactor
  • Semi-continuous centrifuge (particles with a size down to 10 nm can be separated from aqueous suspensions)
  • Laboratory and ultracentrifuge (particles with a size down to 5 nm can be separated from aqueous suspensions)
  • Spray-drying facility (for drying aqueous and non-aqueous suspensions in an oxygen or nitrogen atmosphere, grain sizes of about 3 – 30 μm are obtained)
  • Continuous flow globe mill (disperses particles in solvents and grinds them down to a size of 100 nm)
  • Short path evaporator (gentle separation and recovery of high-boiling solvents in high vacuum atmosphere)
  • Magnetic drum separator (for effective removal of large quantities of magnetic particles)
  • Encapsulation device (for encapsulation of liquid or liquifiable substances)
  • Ultrafiltration
  • Glass autoclave (stirred autoclave for small to medium synthesis volumes up to 2 liters)
  • Fluidised bed reactor (for drying, granulating and coating)
