Surfactants and Micelles: Colloidal Stability

This lecture covers the importance of powder treatment in ceramic production, focusing on the role of surfactants and micelles in achieving steric stability. It explains how the dispersion of particles impacts the quality of ceramics, emphasizing the significance of factors like rheology, sedimentation volume, and green body density. The presentation delves into the assessment of colloidal stability and the formation of micelles, discussing topics such as amphiphilic molecules, self-assembly, and energetics of micellar solutions. It also explores the effects of electrostatic interactions on critical micellar concentration and the application of surfactants in everyday products like detergents.
