Tailored particle design in pulsating hot gas flow
A pulsating hot gas is generated in a specially designed combustion chamber, providing unique thermodynamic conditions for the formation of high-performance powders with exceptional properties. The heat transfer from gas to particle is up to five times higher due to the pulsation of the gas flow, as a result of which the particle formation and phase conversion take place much more quickly. This leads to the formation of unique structures. The process enables something unprecedented – the precise configuration of particles with property combinations which were previously unachievable. What’s more, this innovative technique offers various process options such as drying, calcination, particle formation, and particle coating in a single cost-effective process step.

A previously unachievable quality in powder synthesis
The starting material is applied as a powder or sprayed as a solution or suspension into the hot gas flow, where it is then heated. This leads to chemical or mineralogical reactions and a change to the structure, morphology or particle size. As a result of the high degree of turbulence, pulsating gas flows do not demonstrate the same temperature and speed gradients that would typically be found in continuous gas flows. The exact same parameters are therefore applied to all the particles, resulting in a very homogeneous powder. Configuring and regulating the process temperature in a targeted manner prevents the powder particles from aggregating excessively.

Complex particle systems with exceptional properties
The frequency, amplitude, process temperature, and flow speed of the pulsating gas flow can be freely adjusted with an extremely short retention time. This allows materials which tend to crystallize in conventional techniques to be prepared with amorphous structures in order to increase their catalytic activity, for example. This ability to influence reactions in specific ways also enables you to produce pigments with highly complex stoichiometries – something it would not be possible to achieve with more commonly used techniques.
