Discover interesting possibilities for the synthesis and functionalization of advanced powder particles. Glatt powder synthesis in pulsating hot gas flow as well as processes in the high temperature fluidized bed play an important role. Solutions for complex stoichiometry and crystal structure requirements, for example in mixed oxides, are considered as well as options for organic and inorganic core-shell coating and aspects of calcination. The combination of theoretical considerations and practical experience takes into account different levels of prior knowledge.

The increasing demand for applications within electromobility or stationary energy storage requires the implementation of novel, sustainable and continuous manufacturing processes as well as processes for coating active materials. Aerosol-based methods based on spray drying / spray calcination and spray granulation by powder synthesis and fluid bed technology are presented using selected examples. First results on electrochemical characterisation are shown.
The Glatt Powder Synthesis is not only suitable to produce powders but also for the coating of materials. Starting from suspensions, drying, coating and calcination can be done in one step by a core-shell process.
Besides the presentation of the technology, the fabrication of photocatalysts as well as oxide materials for the generation of hydrogen will be exemplified.
In January 2022, plant manufacturer and process expert, Glatt Ingenieurtechnik, expanded its powder synthesis capacity at the company’s technology center in Weimar. The newly installed system ensures a homogenous process temperature throughout the entire length of the ProAPP® 80 HT reactor or the targeted adjustment of temperature gradients. This allows different process steps to be combined.
SaMBa research project for a novel fabrication process for high permeability oxygen membranes and development of an innovative membrane connection plate for oxygen generators: “Mixed ionic electronic conductor” (MIEC) Membranes are specialized single phase materials which exhibit significant electron and ionic conductivity. Neutral molecules can be transported through a solid membrane and separated from other components. BSCF (barium-strontium-cobalt-iron oxide) enables oxygen exchange. Research focuses on the production of BSCF by Glatt powder synthesis and the subsequent production of the membranes for oxygen separation from air.
At its Hermsdorf site, the Fraunhofer Institute for Ceramic Technologies and Systems IKTS creates high-performance oxide ceramics for medical technology and optical components. The world’s first Glatt synthesis reactor for temperatures up to 1300°C was recently put into operation there, with the powder synthesis process based, for the first time, on a flameless concept with pulsating gas flow.
