Ceramics: Powder Sintering

This lecture covers the drying and debinding processes in ceramic manufacturing, emphasizing the importance of proper conditioning before sintering. It delves into the mechanisms causing cracking during drying, the objectives of debinding, and the different forming methods used. The sintering process is thoroughly explained, focusing on the heat treatment leading to strong bonds between ceramic particles without complete melting. The lecture also explores the driving forces and mechanisms behind sintering, as well as the mass transport mechanisms and grain growth during the process. Additionally, it discusses the influence of temperature on diffusion mechanisms and the impact of particle size on sintering rate. The session concludes with insights into the stages of sintering and the role of doping in altering microstructural development.
