Fundamentals, defects and defect chemistry, intrinsic, extrinsic defects, defect reactions, diffusion and defects, mechanisms of diffusion, types of diffusion co-efficient, chemical potentials of different systems, diffusional flux equation, ambipolar diffusion, driving force for sintering Solid state and viscous sintering, theoretical analysis, Herrings-Scaling law sintering models and sintering diagrams, initial, intermediate, final stage sintering models. Sintering with an externally applied pressure – Hot Pressing and Hot Isostatic Pressing, stress in densification factor and sintering stress Grain growth and Ostwald ripening. Normal and exaggerated grain growth, grain growth in dense and porous solid, grain growth kinetics, pore-grain boundary interactions, densification and coarsening, simultaneous densification and grain growth Liquid phase sintering, mechanism, stages and microstructure of liquid phase sintering. Pressure assisted liquid phase sintering, activated sintering, vitrification Advanced techniques: Microwave sintering and spark plasma sintering Problems of sintering: Constrained sintering Sintering of thin films Sintering with a chemical reaction. Recent advances in this area.
