Thermal Decomposition of Solids: Kinetics & Synthesis

This lecture covers the thermal decomposition of solids, focusing on the synthesis of powders through chemical methods. It explains the thermodynamics and kinetics involved in the decomposition process, highlighting factors affecting the production of powders. The lecture also delves into the kinetics of solid-solid reactions, discussing models like the shrinking core model and the mechanisms governing the reaction interfaces. Additionally, it explores the effects of size and mixing degree in solid-solid reactions, emphasizing the importance of particle size and initial mixing for successful reactions. The limitations of solid-solid reactions are also addressed, including the need for high temperatures and the risk of sintering and contamination.
