Original Abstract

The paper deals with particle analysis and the evaluation of the shape and size distribution of micro- to nano-sized quartz particles as a key parameter for the evaluation of quality in many industrial fields, particularly for high-purity applications. Samples are analyzed by laser diffraction, the most commonly used method for determining the size of the particles; for precise measurement with the possibility of high-resolution imaging of particles, scanning electron microscopy was applied. For morphological and size analysis of electrically non-conductive micro- to nano-particles under environmentally compatible conditions of elevated gas pressure and humidity, environmental scanning electron microscopy was selected as the most suitable. Moreover, the high-end methods of focused ion beam scanning electron microscopy and serial block-face scanning electron microscopy enabled the analysis of particles in the epoxy resin volume including spatial imaging. The application of image post-processing as an important part of the electron microscopy workflow is also discussed.
