“…Regarding the growth of colloidal films during EPD, Sarkar et al 23 provided another fundamental study observing the deposition of silica particles on silicon wafers as a function of deposition time. They compared the nucleation and growth of the silica particle layer with that of atomic film growth via molecular-beam epitaxy and noticed a prominent similarity between the two processes.…”

“…In particular related to the EPD of nanoparticles, a fundamental study on the formation of deposits during EPD has been provided by Sarkar et al. 15 They observed the deposition of silica particles on silicon wafers as a function of deposition time, and compared the nucleation and growth of the silica particle layer with that of atomic film growth via molecular-beam epitaxy. A striking similarity was found between the two growth processes.…”

Electrophoretic deposition EPD is gaining increasing interest as a processing technique for production of novel inorganic nanostructured and nanoscale materials, including the use of nanoparticles, nanotubes, nanorods and related nanomaterials. Recent advances in the electrophoretic deposition of a great variety of ceramic and metallic nanoparticles, carbon nanotubes and other inorganic nanoscaled materials are discussed in this review. The purpose of the paper is to demonstrate the utility of an applied electric field to manipulate and control the deposition of electrically charged nanoscaled particles and other nanostructures on solid surfaces from liquid suspensions. A wide range of applications has been reviewed, demonstrating the high versatility and suitability of the EPD technique as a convenient nanotechnology processing tool. Nano-enamels and structural coatings, electrodes and films for fuel cells, capacitors, sensors and other microelectronic devices, fibre-reinforced and graded ceramic composites, nanostructured films and coatings for electronic, biomedical, optical, catalytic and electrochemical applications are some of the examples discussed. The combination of sol-gel methods and EPD for production of a variety of nanomaterials is also reviewed.

“…Experimentally the coagulation was observed and measured in-situ [22][23][24][25]. But a better understanding of this mechanism is necessary to understand the self-organization of monosized SiO 2 particle layers [26]. This would be of great importance for the self-healing of faults during the deposition of thin dense layers.…”

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
