In this paper a production study of micro encapsulated NaNO3 particles for the application in heat storage systems is presented. Particles loads with different initial size between 100 μm and 400 μm are successfully coated with polyimide in a fluidized bed reactor. During the coating process the particles tend to agglomeration, which can be diminished by adapting the process settings. After successful mechanical stress tests, the thermal stress test of the produced particles discovered that the particles are subject to some kind of chemical reaction leading to a destruction of micro particles.
