Due to the widespread use, studying the structure of silica is of general interest for fundamental research and for applications. For example, it is well known that rubber filled with silica can be used to improve the mechanical properties of the composite material. The goal of many different material models is to describe this so called reinforcement effect. The models depend on reliable information about the structure of the filler. However, the length scales involved range from nanometers up to millimeters and thus a complete study does not exist. Using synchrotron X-ray tomography experiments we are able to study the structure of silica in rubber with a resolution of 600 nm. Thus, one can investigate the micro dispersion of silica in rubber.
