This article discusses recent synchrotron radiation based measurements of nanoparticles formation between arcing contacts. In these measurements, the mean size and surface morphology of the particles was determined by fitting a socalled Universal function to the scattering data which consists of scattered X-ray intensity plotted as a function of q = (4pi/λ)sin θ/2 where θ is the scattering angle and λ, the x-ray wavelength. By taking the inverse Fourier Transform of this scattering function, it is possible to determine the particle size distribution. We shall present this data, taken as a function of height above the interelectrode axis for the case of Ag, AgSnO2 and C contacts.
