Slip casted Al2O3 samples from DBD activated powders exhibited finer pore size distribution and higher sinterability. Final microstructure of sintered samples had the grain size reduced by a factor of 1.7. The performance of electrophoretic deposition (EPD) reduced significantly the deposited layer surface roughness, due to the reduced deposition rate and reversed deposition polarity from cathodic to anodic. To address the nature of underlying physico-chemical processes, DBD plasma activated Al2O3 as well as yttria stabilized ZrO2 powders were thoroughly investigated by means of thermal desorption spectroscopy. We have found that plasma treated powders contains additional oxygen, nitrogen monoxide, nitrogen dioxide and carbon dioxide functional groups. Performed experiments pointed out top the important role of plasma originated molecular gasses physisorbed on the ceramic particles surface.
