Development of an efficient production technology for the synthesis of high-purity, stoichiometrically and morphologically defined nanopowders

The production of transparent and optoceramics but also active materials for battery storages or oxide ceramics for medical devices increasingly requires powder materials characterized by nanoscale grain sizes, high purity and a defined phase composition. However, high prices and, in many cases, the still severely limited availability of suitable powders make it considerably more difficult to establish products based on them, which is primarily due to limitations in the synthesis technologies available today.

Against this background, innovative technical concepts for powder synthesis are needed to overcome today’s limiting process and quality constraints and thus, for the first time, create the conditions for the industrial production of highly sophisticated powder materials. The novel technology of flameless pulsating spray pyrolysis (“powder synthesis”) developed by Glatt Ingenieurtechnik has, in principle, a particularly high potential for the production of high-purity powder raw materials. However, the process temperatures of well over 1,000 °C required for such material syntheses lead to extremely high energy consumption and, at the same time, only low product yields, and are not marketable or competitive with the current plant engineering solutions.
