Sintering Fundamentals: Sol-Gel and Thin Films

This lecture covers the fundamentals of sintering, focusing on the sol-gel process and thin films. It explains the solution precipitation stage, matter flow by diffusion, and the relationship between pressure and particles. The importance of good solubility in the liquid phase for densification is highlighted, while caution against excessive solubility to avoid swelling is emphasized. Examples of co-firing ceramics and the use of organic pore formers to control porosity are also discussed.
