This lecture covers the process of forming ceramic powders to create green bodies, including dry pressing, wet shaping, plastic forming, and additive manufacturing techniques. It discusses the challenges and objectives of each method, such as achieving homogeneous green bodies and minimizing defects. Various shaping techniques like uniaxial and isostatic pressing, slip casting, and plastic forming are explained. The lecture also delves into the importance of drying and debinding processes in ceramic powder forming, highlighting the impact of density gradients and energy storage during pressing. Additionally, it explores examples of ceramic products made through different shaping methods, emphasizing the diverse applications and properties required for each. The session concludes with insights into the significance of removing organic additives before sintering.
