Abstract
The surface characteristics of pure AlN powders are compared with thos e of so-called water stabilized powders. Both commercially available p owders and stearic acid coated powders are used. By means of XPS, diff use reflectance infrared spectroscopy and thermally programmed desorpt ion mass spectrometry, information is obtained about the presence of s urface groups. The behaviour of the different powders in aqueous suspe nsion is compared by means of pH measurements and determination of the isoelectric points.
