Summary

Fine-grained, uniform and dense pore-free microstructures are desirable for the efficient manufacturing of high-performance ceramic products. Comparative investigations of different submicron powders were made and advanced liquid shaping was used for manufacturing of alumina components. Colloidal processing was estimated as most effective in producing high-dense green bodies. Alumina suspensions with different solids loading, pH and dispersant were produced, rheological properties and their impact on green densities were investigated. Green bodies were shaped by electrophoretic deposition and their density, pore size and microstructure were evaluated. Sintering of the samples at different temperatures was performed.
