Glatt Powder Synthesis Reactor ProAPP Lab at IKTS

World’s first flameless high-temperature powder synthesis plant

The German Fraunhofer Institute for Ceramic Technologies and Systems IKTS relies on technology from Glatt for high-purity, high-performance oxide 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.

Ceramic high-performance materials play a fundamental role in almost all forward-looking industries: mechanical engineering, automotive engineering, electronics, energy, biotechnology and medical technology are just some of the sectors in which IKTS conducts research. For the production of application-specific oxide nanopowders, the researchers now use the powder synthesis technology of plant manufacturer Glatt to produce powders on a kilogram scale (funded by the Thüringer Aufbaubank (TAB), FKZ: 2017 FGI 0038 and co-financed with ERDF).

The technology combines spray drying and spray calcination processes, and enables the precise design of new powder types with precisely adjusted properties in a pulsating gas flow. A reactor heater was installed in the Glatt ProAPP® Lab synthesis reactor, which ensures a constant gas temperature of up to 1300°C throughout. This powder synthesis process makes it possible to specifically define the phase state, morphology, grain size and grain size distribution of the primary particles, and produce them to a consistently high quality.

Company information

Glatt Ingenieurtechnik GmbH
Glatt Ingenieurtechnik GmbH
Glatt is specialized in intelligent particle design for the generation and functionalization of powders and granulates with defined, adjustable properties. The focus is on particles and powders for pigments, catalytic, ceramic or battery materials as well as for granules and pellets as additives for e.g. industrial salts, detergents and cleaning agents, fertilizers, pesticides, food, feed, dietary supplements and pharmaceuticals. Encapsulation of flavors, enzymes, vitamins, microorganisms, probiotics or fatty acids (PUFA) is just as possible as encapsulation of essential oils and other active, sensitive substances to be protected. With Glatt APPtec®, a unique technology for spray calcination, it is possible to generate, coat and then calcine particles in a pulsing hot gas stream in a single process step. As a pioneer in fluid bed and spouted bed technologies, Glatt masters these important processes for the formulation and optimization of particle properties through defined spray agglomeration, spray granulation, spray coating or (micro)encapsulation as well as through combinations of these processes. Also in the high temperature range. Glatt supports the product idea from the early phase of product formulation through process development to scale-up to production scale. Under the leadership of the Glatt Process & Plant Engineering teams, customized production plants for nutrition, fine chemicals, pharmaceuticals, and biotech applications are successfully planned and commissioned. Worldwide. Whether based on powder synthesis, fluid bed or spouted bed technology, Glatt also offers certified contract manufacturing for customers without their own production capacities.
