Ceramic Powders: Fragmentation Operations

This lecture covers the transformation of ceramic powders through fragmentation operations, including dry and wet fragmentation, particle rupture mechanisms, and the classification and types of classifiers used in the process. It explains the importance of transforming powders, the different density properties, and the various forces and failure mechanisms involved in particle breakage. The lecture also delves into the critical consequences linked to fragmentation, the breaking stresses, and size limits. Additionally, it discusses the dispersion of powders, wetting properties, and the colloidal stability of dispersions. The main focus is on interparticle forces, such as van der Waals forces, and their impact on material properties.
