Observation of internal structure of granule compact with immersion resin with fluorescent dye

Abstract

We report a novel method for characterizing the internal structure of granule compact of high reflective index. Resin with fluorescent dye was immersed into the compact. Cross section of compact with resin was observed by confocal laser scanning microscopy (CSLM). Network structure of deformed granules in the compact was observed. This method has a potential to observe an internal structure of granule compact with powders of high reflective index.
