Direct observation of large scale heterogeneity in ceramic slurry

Abstract

We present a unique technique to observe directly the large scale heterogeneity in ceramic slurry. In this technique, the slurry was thinned down to about 100μm. Then, the internal structure in slurry was successfully visualized using an optical microscopy with a transmission mode. The structural changes in slurry with regard to time, temperature and shear flow have been also observed directly.
