Colloidal Stability and Steric Stabilization

This lecture covers the concepts of colloidal stability, electrostatic forces, and steric stabilization in ceramic powder dispersions. It explains the role of double layers, DLVO theory, and the impact of polymer adsorption on particle interactions. The instructor discusses the importance of surface roughness, the isoelectric point, and the influence of ionic concentration on stability. Various polymer conformations and their effects on repulsion are explored. The lecture concludes with a detailed analysis of the total interaction energy and the challenges in predicting colloidal stability. Practical examples and theoretical models are used to illustrate key concepts.
