Summary
Most materials e.g. ceramics, metals, polymers or concrete pass during their processing one or more steps in powders. This course discusses and presents the science & technology of important powder processing steps like compaction, dispersion, sintering and novel densification technologies.Content
- Theoretical and empirical models for powder packing and compaction including disctete element modelling (DEM) (examples for ceramics and metals)
- Particle- particle interactions (colloidal chemistry, DLVO theory, non-DLVO forces , polymer adsorption, colloidal stability assessment). Examples from cement and concrete, landslides, ceramic powder granulation, paper coating.
- Introduction to atomistic modelling - with examples from grain boundary segregation of dopants in ceramics, polmyer adsorption and cyrstal growth
- Sintering mechanisms (metal, ceramics, influence of the microstructure, simulation)
- Novel technologies (includes rapid prototyping)
- The support material for the course are copies of the slides used to present the course along with a few key text books and review articles - which the students are encouraged to use to supplement the documents provided.
