Ceramic Forming Methods: Drying & Binder Removal

This lecture covers ceramic forming methods such as dry pressing, tape casting, slip casting, drying, and binder removal. It discusses the importance of particle packing, compaction, sphericity, size distribution, and density gradients in green bodies. Various techniques like uniaxial dry pressing, cold isostatic pressing, and slip casting are explained, along with the role of additives like polyvinyl alcohol and polyethylene glycol. The process of ejection, density distribution, and defects in dry pressing are also addressed, emphasizing the need for optimal pressure and organic additives. Additionally, slip casting practical aspects, filter pressing, and the significance of suspensions' solids loading for high-density green bodies are highlighted.
