Ceramic Powders: Shaping and Granulation Techniques

This lecture covers the shaping and granulation techniques for ceramic powders, including spray atomization, gel atomization, and fluidized beds. It discusses the principles of spray atomization, the effects of thermal gelation, and the properties controlled by organic additives. The lecture also explores the rheology of ceramic suspensions, the impact of powder surface charge on viscosity, and common faults found in ceramics. Various fitness methods, such as dry pressing and slip casting, are explained, along with their benefits and applications in producing ceramic parts. Additionally, the lecture delves into additive manufacturing techniques for ceramics, including extrusion and layer-by-layer fabrication.
