A novel parameter, the fractal exponent D E , is derived using the concept of fractal scaling. The fractal exponent D E relates the development of a feature within a material to the development of the size of the material. As an application, structural changes during the compaction and sintering of ceramic materials have been characterized with the fractal exponent D E . Samples taken during the processing of (Mn,Zn)-ferrite, a soft magnetic ceramic material, were analysed with porosimetry. Results show that the fractal exponent D E provides additional insight into the processing.
