Liquid Phase Sintering: Fundamentals & Applications

This lecture covers the fundamentals of liquid phase sintering, discussing the importance of controlling grain size, pore size, and boundary interactions. It explains the conditions for abnormal grain growth and the role of dopants in achieving high-density ceramics. The presentation delves into the stages of sintering, emphasizing the need for an optimal sintering strategy for each application. It also explores the impact of densification mechanisms and coarsening on the final microstructure of ceramics. Various examples and simulations are used to illustrate the concepts, such as the influence of heating rates on grain size and the use of thermomechanical analysis for controlled sintering.
