Alle stabilen Suspensionen weisen im entsprechenden pH-Bereich eine monomodale Partikelgrößenverteilung auf. Durch die Charakterisierung der Suspensionen mit der Ultraschallspektroskopie kann eine verbesserte Bewertung hinsichtlich Homogenität und Agglomeratbildung auch für nanoskalige Pulver erhalten werden. Dies ermöglicht eine bessere Qualitätskontrolle prozessrelevanter Schritte bei der Verarbeitung.

For all material pairs, friction and wear depended largely on the relative humidity of the environment. When paired with steel the low IR-emission ceramic disks showed higher wear resistance. Under dry conditions, almost no wear was found on the low IR-emission ceramic specimen. The high wear on the steel counter body is caused not only by tribo-oxidation, which is the main wear mechanism, but also by abrasion. In dry conditions a COF of 0.6 and in humid conditions a COF of 0.2 have been measured. When paired with α-alumina the results on wear are just opposite to those with steel counterbody and the low IR-emission ceramic materials show much lower wear resistance under all conditions. This is explained by the predominance of abrasion and the relatively large difference in hardness between the low IR-emission ceramic and α-alumina. In high humidity environments the results point to the formation of stable reaction layers causing lower friction and wear.
