Powder Treatment: Milling and Classification

This lecture covers the process of powder treatment, focusing on milling and classification techniques used in the production of ceramics. Topics include crushing, milling, particle breakage, classification, and the characteristics of different types of classifiers. The instructor discusses the importance of powder characteristics such as chemical purity, reactivity, and homogeneity, as well as the practical aspects and scientific principles of powder synthesis. Various methods of powder synthesis, including solid-solid, solid-gas, and precipitation routes, are explored. Additionally, the lecture delves into the effects of milling on particle size distribution, the use of different materials for milling ceramics, and the advantages of wet and dry milling processes.
