Ceramic Materials Revision

This lecture covers the characterization of ceramic materials, including sampling, physical and chemical properties, particle size distribution measurement issues, and common analysis methods. It also discusses the synthesis of ceramic powders, emphasizing sources, options, and key concepts like spray atomization and calcination. Furthermore, it explores powder transformation processes, focusing on particle control, additives, and impurities. The lecture delves into shaping techniques such as dry pressing and wet forming, as well as debinding and sintering processes to achieve dense ceramic bodies. Lastly, it addresses the importance of densification, grain growth, and final properties through delubrication and sintering, with a detailed look at the Coble model.
