Powder Synthesis: Solid Reactions

This lecture covers the synthesis of powders through solid-solid and solid-vapour reactions. It delves into the kinetics and limitations of these reactions, including the use of high temperatures and milling for product formation. The Acheson method for SiC synthesis is explained, highlighting the complex mechanisms involved. The importance of particle size, gas pressures, and rate-limiting steps in solid-vapour reactions is also discussed, along with the nucleation and growth processes in precipitation reactions.
