Abstract
Colloidal processing has demonstrated its suitability to produce complex shaped ceramics and ceramic–metal composites with tailored microstructure. By combining different shaping methods, it is possible to produce complex three-dimensional bodies as well as single or multilayer coatings, self-sustaining films and laminates. This work summarises the main features of colloidal processing, including colloidal stability and stabilising mechanisms focusing the importance of the rheological behaviour in the shaping step. The most common shaping methods and consolidation mechanisms based on suspensions are presented as well as their capabilities for producing composites with complex shapes and microstructures.
