Abstract

V originále

Aluminium oxide nanopowder is used for sintering into ceramic materials with attractive mechanical properties. The simplest and most common sintering methods are wet methods during which the nanopowder is dispersed in a liquid. High surface energy increases the quality of the sintered material. Atmospheric pressure plasma is known improve its wetting properties and the quality of ceramic sintered using the electrophoretic method. However, polarisation abnormalities during the deposition suggested an addition of negatively charged species on the powder's surface during the treatment, probably NOX molecules. To verify this hypothesis, we have used the Thermal Desorption Spectroscopy on the treated and the untreated nanopowder to study the changes that occurred during the treatment. We have found that a large number of additional NO, NO2, CO2 and hydroxyl were attached to the surface, at least some of them were grafted rather than adsorbed. This provided additional evidence that the abnormalities were caused by NOX molecules on the surface.
