For the preparation of advanced materials via a powder technological route the shaping process is most important after the synthesis of the powder. Therefore high production rates and the formation of a homogeneous compact are generally desirable. Furthermore, a high green density is necessary to reduce shrinkage during drying and sintering. This is of special importance for near net shaping or microstructuring. For coatings an even thickness with a good coverage of the edges is an additional specification that has to be fulfilled. The typical shaping processes for fine or advanced ceramics with particle sizes in the µm or even sub-µm region are slip casting, forming of high-viscous masses, and dry pressing. The decreasing of particles size leads to the area of nanoparticles with sizes less than 100 nm. These nanopowders show higher sintering activity leading to a decrease of sintering temperature. Thus smaller final grain sizes can be achieved or even quantum size effects can be observed. For glasses new perspectives are opened with nanopowders. Due to the reduction of processing temperatures nanosized glass powders can be completely sintered to transparent glasses via viscous flow below the crystallization temperature. Thus no crucibles are needed any more and high-purity glasses can be prepared. For coatings on substrates with limited temperature stability glazes and enamels can be applied without additional low melting components. Theses fluxes generally reduce the chemical stability of the coating.As these nanopowders tend to aggregate due to the increased influence of van der Waals attraction forces, these nanopowders have to be dispersed perfectly. For that suspensions are most suited and the formation of aerosols (dust of nanopowders) is prevented, which might be hazardous. In electrostatically stabilized suspensions the dispersed particles show a surface charge, which can be directly used for moving this particles in an applied external electric field leading to an electrophoretic deposition (EPD) [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. But it should be kept in mind that the electrostatical as well as

We develop and evaluate a semi-empirical particle-based model of electrophoresis using extensive mesoscale simulations. We parameterize the model using only measurable quantities from a broad set of colloidal suspensions with properties that span the experimentally relevant regime. With sufficient sampling, simulated diffusivities and electrophoretic velocities match predictions of the ubiquitous Stokes-Einstein and Henry equations, respectively. This agreement holds for non-polar and aqueous solvents or ionic liquid colloidal suspensions under a wide range of applied electric fields.) unless CC License in place (see abstract). ecsdl.org/site/terms_use address.
