Kurzfassung
The addition of ferroelectric microparticles embedded in a nanostructured silica aerogel modifies the dry gel microstructure in a measurable way. The pore size distribution changes as well as the specific surface area. This indicates a possible positive effect of particles on the gelation characteristics. These modifications were observed in solutions gelling during a sounding rocket experiment in which approximately three minutes microgravity provided sufficient time for a convection and sedimentation free gelation to occur. The paper describes the synthesis procedures and the microstructures obtained for the gels under microgravity conditions.
