This lecture covers the processing of ceramic materials, focusing on the treatment of powders through grinding, dispersion, and atomization. It explains the importance of these processes in breaking agglomerates and achieving homogeneous compositions for optimal physical and mechanical properties. Various examples and techniques are discussed, such as dry and wet grinding, as well as the use of additives. The lecture also delves into the energy efficiency and industrial significance of powder transformation, emphasizing the challenges in modeling and predicting grinding mechanisms. Different types of mills and their operational principles are explored, including ball mills and attritors. The session concludes with insights into particle fracture mechanisms and the forces involved in particle size reduction.
