Glatt Powder Synthesis for Nanoparticles – This is how it works

Glatt powder synthesis is a process for the production, modification or coating of powder particles in the nano and micrometer range. Solutions, suspensions or solids are sprayed into a pulsating gas stream. In the gas stream, the materials are dried, coated or thermally modified and subsequently quenched and separated in the filter. The whole process takes less than a second. The pulsating gas stream has significant advantages over a laminar gas stream. The pulsating gas flow is turbulent, preventing gradients in temperature and residence time. The pulsating gas flow also removes the boundary surfaces at the resulting particles, allowing up to five times faster energy input into the particles.

The solvent, preferably water, evaporates and the dissolved material dries very rapidly. From solutions homogeneous particles are formed and suspensions generate core-shell particles. The solid particles can subsequently be thermally treated. Chemical, crystallographic and surface properties are changed and customized. At the end of the reaction zone, these structures are cooled (quenched) with a cold gas in less than one second and the structure is “frozen”. The material can now be separated and isolated in various filters.
