Abstract. In this study, a high energy ball milling process was introduced in order to improve the densification of direct nitrided AlN powder. The sintering behavior and thermal conductivity of the AlN milled powder was investigated. The mixture of AlN powder and 5 wt% Y2O3 as a sintering additive was pulverized and dispersed by a bead mill...

Highenergy ball milling is an ideal method for particle size reduction and the analysis of subsequent chemical and physical changes. The characteristics of particle size reduction and following growth were similar with all oxides analyzed.
A suitable tool for this method is a planetary ball mill, such as RETSCH's PM 100, PM 200 or PM 400, which provides the necessary energy input. The common rules for size reduction to micron size do not apply for the nanoscale; with decreasing particle size, electrostatic and even molecular interactions increase, leading to particle ...
