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.
With an advanced powder synthesis process, particularly high-quality nano- and microscale powders can be produced or refined – for example, for dental implants. To make the properties of zirconium oxide powders, which are also used in other medical and technical products, even more specific, the particles can be coated, for example. Glatt powder synthesis, a further development of the spray calcination process, is suitable for this purpose. (German article)
Powder synthesis represents a novel process for the production, activation and coating of battery materials. By using a pulsating hot gas flow with adjustable frequencies and amplitudes, powders of the highest quality can be produced. Solutions to address current shortcomings as innovation drivers for new battery materials.
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.

To commercialize next-generation cathode materials a lot of different synthesis methods need to be researched and evaluated regarding the attainable electrochemical properties of the materials on one hand, and the scalability of the process on the other. For the high voltage LiNi0.5Mn1.5O4 cathode material especially the degradation of the material during cycling needs to be investigated for different scales and techniques. LiNi0.5Mn1.5O4 (LNMO) was synthesized using two different methods in different scales: lab-scaled spray drying and pilot-scaled gas pulse drying.
