Flame spray pyrolysis is a promising, scalable and cost-effective route for the synthesis of a wide spectrum of nanoparticles, by means of a high-temperature gas-phase process.

Raw materials are solutions containing the appropriate metallorganic precursor for particle formation. The growth process can be controlled modifying the precursor concentration and the flame parameters. Produced nanoparticles are collected on filters as dry powder.

The main advantages of the FSP process are:

  • short process chain,
  • flexibility of the process,
  • production of multi-component materials in one step,
  • possibility of process scale-up for cost-efficient large scale-production of nanoparticles.
