Fine and homogeneous powders can be produced

Narrow particle size distributions

Precisely definable chemical composition

Extremely homogeneous thermal treatment of the material

No hard aggregates, no hot spots

Continuous, easily scalable process

Temperature treatment up to 750 °C (optional 1300 °C) possible

Very high heat and mass transfer rates

Glatt powder synthesis is distinguished from other production methods by its constant flow and increasing pulsation intensity which cause the boundary layer around particles to be almost completely eliminated. Heat and mass transfer are therefore up to five times faster.

The particles form, dry and heat up extremely quickly in Glatt powder synthesis. They are cooled just as quickly at the outlet of the reactor. This accelerated particle formation and phase transformation ensure the desired reaction states and enable the formation of unique structures.

Glatt powder synthesis enables homogeneous distribution of the reaction components during the production process, resulting in uniform particle structures. Time-consuming and energy-intensive particle grinding is not necessary.

In particle design with Glatt powder synthesis, process steps such as drying, calcination and particle formation are combined in a single step. If required, functional core shell particles with specific layer thickness, porosity and activity properties can be produced. Since no local hot spots are formed in the reactor, no hard aggregates are formed. This makes it easy to separate and disperse the individual particles. This is a further advantage over other processes. If the heat treatment there is too intensive or not homogeneous, hotspots form. This can occur, for example, during flame pyrolysis, in plasma reactors or in rotary kilns.

The thermodynamic conditions of Glatt powder synthesis can easily be adjusted by targeted process control. Process conditions such as temperature, residence time, frequency and amplitude are as all precisely set, as is the flow rate of the process gas. In addition, an oxidizing or oxygen-free gas atmosphere can be used – depending on the application.
