Powder Synthesis: Methods and Applications

This lecture covers various methods of powder synthesis, including Sol-Gel precipitation, hydrothermal synthesis, spray-pyrolysis, and vapor phase synthesis. It explains the principles, mechanisms, and applications of each method, highlighting the importance of controlled conditions in producing high-purity ceramic powders. The lecture also discusses scaling-up strategies using tubular reactors and segmented flow reactors, emphasizing the significance of efficient mixing and narrow particle size distribution. Additionally, it explores the thermodynamics of powder synthesis, focusing on Gibbs free energy and supersaturation as driving forces for solid formation. Surface energy and its impact on material properties are also discussed.
